Can Cataracts Come Back After Surgery?

Cataracts, or an opacification or clouding of the eye’s lens, affect millions of people – it’s one of the most common eye conditions in the world. Cataracts often affect older people, although it’s possible for them to develop in younger patients as well. Today, laser surgery is commonly used to remove cataracts, and it has a high success rate. Traditional cataract surgery using blades is also still commonly used to great effect.

Have you ever wondered whether cataracts can come back after surgery?

The answer isn’t quite as simple as a “yes” or “no.” Cataracts cannot grow back once they’ve been removed. But it is possible for a secondary (or new) cataract to form. So, yes, cataracts can come back after cataract surgery; it’s not the old one growing back, but a new one forming. The medical term for this is posterior capsular opacification, or PCO.

Let’s take a closer look at how cataracts surgery works and how secondary cataracts or PCO happens. Then, we’ll discuss the symptoms of this condition and what can be done about it to help patients see clearly once again.

How Does Cataract Surgery Work?

There are two types of cataract surgery: traditional cataract surgery, which has been used for many years, and the newer laser-assisted cataract surgery.

Traditional Cataract Surgery

This type of cataract surgery involves using a tiny blade to make an incision on the side of the eye’s lens (the cornea) and removing the clouded lens. After that, an artificial lens called an intraocular lens is inserted in place of the natural lens. In some cases, sutures might be needed to close the incision, but more often than not the incision is left alone to heal over time. Most patients are fully healed within a few days or weeks of cataract surgery.

Laser Cataract Surgery

Laser-assisted cataract surgery uses laser technology and 3D imaging to make the incision. An advanced laser called a femtosecond laser creates an opening in the cornea’s front layer, and then the laser breaks

up the clouded lens before it’s sucked out through the incision. Then, an intraocular lens replaces the natural lens in the same manner as traditional cataract surgery.

Both types of cataract surgery are fast, efficient, and very safe. They’re both widely used today, including by top cataract surgeons in Buffalo. In fact, cataract surgery is one of the most common types of surgery performed in the world, with a very high success rate.

Can You Have Cataracts Twice?

As mentioned above, yes, you can have cataracts twice, even after surgery. Secondary cataracts, sometimes called after-cataracts, isn’t particularly common but it is possible.

Secondary cataracts doesn’t develop immediately after your cataract surgery. It will typically take months or, even more commonly, years before developing. And here’s the good news: it’s less common than ever before. For many years, nearly half of all patients who had cataract surgery developed secondary cataracts at some point. Now, thanks to technological improvements particularly in laser surgery, only about four to 12 percent of patients experience secondary cataracts.

PCO is still the most common complication after cataract surgery, but it occurs less frequently than ever before. And research is ongoing into ways to make it even less common.

What is a Secondary Cataract?

Secondary cataracts or posterior capsular opacification (PCO) occurs when the membrane around the lens capsule (not removed during surgery) becomes cloudy and starts to impair vision. New protein cells begin to grow on the back of the lens capsule, which obscures vision just like a cataract does.

There are actually two types of secondary cataracts:

· Pearl PCO: Responsible for the majority of secondary cataracts cases, pearl PCO involves normal differentiation of lens epithelial cells (LECs) in the equatorial lens region.

· Fibrous PCO: Fibrous PCO involves abnormal growth of LECs in the lens.

To put it simply, secondary cataracts is the opacification of the membrane around the lens capsule, which wasn’t removed during cataract surgery. It usually starts to opacify months or years after cataract surgery.

What Makes Secondary Cataracts More Likely?

The development of secondary cataracts is, on the whole, not extremely common. But there are a few conditions and factors that make this condition more likely to occur. One is age; it turns out that younger cataracts patients are more likely to develop secondary cataracts. Other factors include:

· Diabetes – Diabetes and vision problems are closely linked. Patients who have diabetes or had it in the past have a higher incidence of PCO development.

· Uveitis – Uveitis occurs when the uvea, the middle part of the eye, becomes inflamed. This results in itching and redness. Patients with this condition are more likely to develop secondary cataracts.

· Myotonic dystrophy – Related to muscular dystrophy, myotonic dystrophy is an inherited disease that involves prolonged muscle contractions and difficulty relaxing certain muscle groups. Cataracts often develop as a symptom of this condition, and people with myotonic dystrophy often require multiple capsulectomies to restore proper vision.

· Retinitis pigmentosa – People with retinitis pigmentosa have a higher occurrence rate of secondary cataracts. This condition involves the breakdown of cells in the retina, which causes symptoms like loss of peripheral vision and difficulty seeing at night.

· Cataracts caused by trauma – It’s possible for cataracts to be caused by injury or trauma to the head or eye. When this is the case, the chance of secondary cataracts occurring is much higher.

Secondary Cataract Symptoms

What are the main secondary cataract symptoms? How can you tell if you’re developing this condition?

Blurry Vision

Blurry vision after cataract surgery is the most common sign of secondary cataracts. As mentioned, the blurred vision won’t occur immediately after surgery. It will probably happen months or even years afterward.

Glare/Halos

Patients might notice an increased glare from light sources, such as the sun or car headlights when driving at night. It’s also relatively common for those with secondary cataracts to see halos around these light sources.

Lack of Visual Acuity

A reduction in visual acuity is another common sign of secondary cataracts. This might manifest in difficulty reading text or seeing the television, difficulty driving and seeing road signs, etc. Patients might also notice a reduction in the accurate perception of colors.

Can Secondary Cataracts Be Prevented?

It is not possible to prevent the occurrence of secondary cataracts in every case. However, there are things that can be done to make it less likely. Advances in surgical techniques are one approach; as the technology improves and processes are further refined, ophthalmologists hope to reduce the risk of secondary cataracts developing. Extensive polishing of the epithelial cells during cataract surgery can also help.

New intraocular lens designs (the artificial lenses that replace the clouded cataract lens) show promise for reducing cataract surgery side effects, including secondary cataracts. Square-edged intraocular lenses can reduce the risk of PCO development, and there is also evidence that changes to the surface chemistry of the lens makes PCO development less likely.

Last but not least, drugs that suppress certain cell growth could be used to inhibit the growth of lens cells that end up obscuring vision. The Food and Drug Administration has not approved prescription drugs for this reason yet, so it remains to be seen if medication could play a role in preventing the development of secondary cataracts.

Secondary Cataract Treatment

Secondary cataracts can certainly be a frustrating thing to deal with. After all, cataract surgery was supposed to solve the issue. It’s understandable that patients are frustrated when their vision becomes blurry once again. Luckily, treating secondary cataracts is generally very simple and easy.

Secondary cataract surgery is performed via a procedure called YAG laser capsulotomy, and it’s widely effective in treating secondary cataracts and helping patients to experience restored vision after the development of secondary cataracts.

YAG Laser Capsulotomy

YAG laser capsulotomy is a quick, painless procedure. First, the eye is numbed with special drops. Then, a laser creates a small opening in the clouded part of the lens capsule. This allows light to shine through to the retina, allowing the lost vision to be restored. Most often, the patient can return home immediately with an eyedrop treatment, and will probably be able to return to normal activities – driving, working, etc. – within a day or two.

YAG laser capsulotomy only takes about five minutes, even less than the already quick cataract surgery itself. You’ll probably need to revisit the eye doctor’s office in a week or so for a follow-up appointment to make sure things are progressing well and you’re not experiencing any side effects.

Why Is My Vision Getting Worse?

Many people know that vision changes can occur at any time. However, if your vision is declining year after year or suddenly takes a turn for the worst, you may wonder why it’s happening.  

Here is a look at common reasons for declining vision, as well as the symptoms you may experience.  

Aging  

As people age, their visual acuity typically decreases, especially when it comes to near-vision. Often, this process is unavoidable. Additionally, it’s normal for vision to decline further as time passes.  

Often, age-related vision changes begin around middle age, commonly among adults over 40. During that time, presbyopia – a loss of lens flexibility – can alter visual acuity, particularly when viewing nearby objects. However, some may not see shifts until they’re far beyond 40, while others may see these changes begin earlier.  

Usually, the most common symptoms of age-related changes are trouble reading small print, fatigue after reading, holding items farther away to read, needing brighter light, and squinting.  

Injury  

An eye injury can lead to a range of physical changes that may impact your vision. If the optic nerve is damaged, it can cause significant vision loss. Similarly, an injury-related retinal detachment may cause a rise in the number of floaters, bright light flashes, and blurriness.  

Eye injuries can also cause other kinds of damage, many of which require quick treatment to prevent or reduce vision loss. Since that’s the case, fast action is always recommended, including seeing your eye health provider for an immediate assessment.  

UV Damage  

UV light harms the eyes, potentially leading to vision changes. Often, the damage begins during childhood, a period when most people aren’t as cautious when it comes to eye health. However, it may not be apparent until adulthood. Additionally, choices as an adult also influence the equation.  

In most cases, UV damage leads to blurriness. Eye pain, redness, and light sensitivity are also symptoms you may experience.  

Eye Strain  

Due to the rise of digital devices, eye strain is surprisingly common, and it can lead to certain vision changes. When people view screens, they tend to blink less. Additionally, they’re keeping their focus on a specific distance.  

In most cases, tiredness or fatigue is the most apparent symptom, coupled with dry, itchy, or burning eyes. However, you may experience headaches, light sensitivity, and soreness, too.  

Cataracts  

Technically, cataracts are another age-related reason for vision decline. As proteins in the lens break down, they can cloud the lens, leading to blurry vision.  

Along with being very common, cataracts are typically incredibly treatable, particularly when caught early. Some signs of cataracts include blurriness, glare, halos, and faded or yellowed colors.  

Glaucoma  

Glaucoma is a condition involving elevated pressure in the eye, leading to damage to the optic nerve. As the damage occurs, peripheral vision typically declines first. Blurriness and halos may also develop, as well as trouble seeing in low-light conditions.  

In some cases, glaucoma is also accompanied by pain. However, that isn’t always the case.  

Since vision changes are potentially caused by a range of conditions, including some severe problems that can lead to permanent vision loss, it’s best to see your eye health provider whenever you notice a shift. Additionally, attending your annual appointments ensures your provider can monitor your eye health and take quick action should they spot an issue that’s yet to result in symptoms.  

At ECVA, the safety and health of our patient’s eyes are our priority. If you are experiencing vision changes or simply haven’t seen your eye care provider in the past year, the ECVA team is here to help. Schedule an appointment at your closest ECVA clinic today.

What Are the Early Signs of Glaucoma?

Glaucoma is an eye condition impacting the optic nerve. As intraocular pressure builds, damage to the optic nerve can occur, leading to permanent vision defects and loss, potentially leading to blindness.  

While glaucoma isn’t typically preventable, early detection is crucial if you want to avoid optic nerve damage and slow the progression of vision loss. By knowing the early signs of glaucoma, you can take action at a critical time, increasing your odds of maintaining as much of your vision as possible.  

Here’s what you need to know about the early signs of glaucoma, as well as when you should see an eye health provider.  

Early Signs of Glaucoma  

Generally, there are a few symptoms that can be early signs of glaucoma. One of the most common ones is the loss of peripheral – or side – vision. Over time, it can lead to a sort of tunnel vision, though the process is often slow and hard to identify right when it begins.  

Halos around light are another symptom of glaucoma. Sensitivity to light is similarly a classic sign. In both of these cases, the issues may be particularly apparent in specific situations, such as driving at night.  

Other forms of vision loss – including a sudden decline in acuity or the visual field – can indicate glaucoma, too. Eye redness and pain could be a symptom of acute glaucoma. Haziness of the cornea is a potential symptom, though it’s usually only present with childhood glaucoma.  

In some cases, unexplained nausea or vomiting may also be related to glaucoma, particularly the acute form. The same goes for headaches and blurry vision.  

When to See an Eye Health Provider  

Ultimately, it’s always wise to see an eye health provider whenever you notice any shifts in the visual field or acuity, as well as symptoms of physical changes in the eye. Glaucoma typically isn’t preventable. However, with proper management, vision loss can be minimized.  

Additionally, some of the early signs of glaucoma are also symptoms of other serious eye conditions. For example, redness and eye pain may indicate an infection and, depending on the type, permanent eye damage can occur with surprising speed. Halos may be a sign of glaucoma, cataracts, retinal detachment, and many other potentially serious conditions, all of which should be assessed quickly to determine if treatment is necessary.  

However, even if you don’t have any of the early signs of glaucoma or symptoms of an eye condition, it’s still wise to see your eye health provider regularly. For most adults, an annual appointment is enough to monitor for vision changes and signs of eye health issues, though some may require more frequent visits if certain risks factors are present or they have an eye condition that requires ongoing treatment and tracking.

Three Common Vision Problems

When it comes to vision problems, refractive errors are the most common ones that people experience. With these, the shape of the eye or its ability to focus light changes, causing different kinds of visual acuity issues or visual anomalies. 

Since refractive errors are so common, it’s wise to understand what they are and how they impact vision. Here’s a look at the three most prominent refractive issues causing vision problems. 

Three Common Vision Problems 

Myopia 

Also called nearsightedness, myopia is a condition where close-up vision remains reasonably strong, but objects far away look blurrier than they should. The condition develops when changes to the shape of the eye alter where light is focused in the eye, causing it to concentrate in front of the retina instead of on it. 

Usually, the most obvious symptom of myopia is issues with long-distance vision. However, needing to squint to see clearly and eye strain can both be symptoms. The same goes for headaches, though those aren’t as common as with certain other refractive errors. 

Hyperopia 

Hyperopia – also called farsightedness – is a condition where close-up vision degrades while distance vision remains intact. It occurs when changes in the shape of the eye cause light to focus behind the retina instead of on it. 

With hyperopia, trouble seeing objects up close is the most definitive symptom of the condition. However, eye strain and headaches, particularly when reading or doing other up-close activities, can also be signs of farsightedness. 

Astigmatism 

Astigmatism is a condition where the cornea or lens of the eye change shape. Usually, this leads to visual distortions or blurriness, depending on the nature of the changes. Often the distortions are particularly noticeable when looking at a light at night, such as oncoming vehicle headlights after dark. The lights may look streaky, starred, or haloed, depending on the nature of the eye changes. 

Blurry vision is another common sign of astigmatism, as well as needing to squint to see clearly. Trouble seeing at night may also be a symptom, along with eye strain and headaches. 

It’s important to note that a person can have myopia or hyperopia and astigmatism. That means it’s possible to have two refractive errors impacting your vision. 

Treating Refractive Errors 

Refractive errors are traditionally treated with corrective lenses. This can include prescription glasses or contacts. With those, the lens can compensate for the changes in the eye that lead to the vision change, allowing a person to see clearly when wearing their glasses or contacts. 

In some cases, alternative vision correction options – like laser eye surgery – may also be an option. However, that will depend on the severity of the vision loss, whether your vision is stable or continuing to change, and certain other factors. 

At ECVA, the safety and health of our patient’s eyes are our priority. If you have signs or symptoms of a refractive error or simply haven’t seen your eye care provider in the past year, the ECVA team is here to help. Schedule an appointment at your closest ECVA clinic today.

How to Protect Vision Right Now

Have a comprehensive eye exam at ECVA today!

The prospect of vision loss is not typically a concern for most people until a decline in visual acuity becomes noticeable. Vision changes typically occur due to aging or an injury. However, there are also preventable factors that contribute to poor vision or diminished eye health as well. Taking inventory of behaviors that put eyes at risk and making important changes can help safeguard the eyes for as long as possible.

Get routine comprehensive wellness exams

The Centers for Disease Control and Prevention (CDC) says about 93 million adults in the United States are at risk for vision loss. Factors that contribute to vision loss can include being overweight or obese, diabetes, high cholesterol, and high blood pressure. A wellness exam also may uncover family history issues that increase risk for hereditary eye conditions.

Receive a dilated vision exam

Many eye diseases, like glaucoma or age-related macular degeneration (AMD), have no warning signs, according to the CDC’s Vision Health Initiative. Thus, the only way to determine if there is an eye health issue or compromised vision is to get a complete vision exam, which includes dilating the pupil to see the retina, blood vessels and other components of the inner eye. This is the only way to detect diseases in their earliest stages.

Step up healthy eating

Many eye-healthy foods are rich in vitamins and minerals. Dark, leafy greens like spinach, kale and collards are good for the eyes, according to the National Eye Institute. In addition, foods rich in omega-3 fatty acids, like salmon, halibut, and tuna are also good choices for maintaining eye health, as they lower the risk for dry eyes and eye diseases such as macular degeneration and cataracts.

Sip on green tea

True Eye Experts says green tea is a great source of antioxidants that can keep eyes healthy and defend them from cataracts and AMD.

Wear protective eyewear

Always don sunglasses with UVA and UVB protection when outdoors. Protective eyewear is a must for those who work in an industry that requires eye protection or athletes who play sports in which eye injuries are a consistent threat.

Discard old cosmetics

Exercise caution with outdated eye makeup. Experts suggest discarding mascara that is more than four months old. Avoid applying eyeliner to the inside of the eyelid, as that can lead to irritation or infection.

Practice smart contact hygiene

Always wash hands before inserting or removing contact lenses. Lenses should be stored properly in cleansing solution and discarded after the recommended amount of time for the particular type of lens (daily, bi-weekly, monthly). Unless they are approved for overnight use, remove contacts before going to bed.

Quit smoking (or don’t start)

Smoking increases a person’s risk of developing various eye diseases and can make diabetic eye disease more severe.

It’s never too late to make changes that can preserve vision.

The Stages of Diabetic Retinopathy

When a person has diabetes, they’re at risk of a debilitating eye condition called diabetic retinopathy. Essentially, elevated blood sugar levels damage blood vessels within the retina, leading to vision issues. Over time, it can even cause significant vision loss, if not blindness. 

Like most medical conditions, diabetic retinopathy occurs in phases. By understanding the stages, it’s possible to slow the development, preserving visual acuity. If you’re not familiar with the phase of diabetic retinopathy, here’s what you need to know about them. 

The Stages of Diabetic Retinopathy 

Mild Nonproliferative Retinopathy 

The first stage is mild nonproliferative retinopathy, also referred to as background retinopathy. During this phase, there are microaneurysms (small bulges) in the blood vessels in the retina, some of which may begin to leak. 

During this stage, there may be no noticeable vision issues. Additionally, treatment might not be required, depending on severity. However, even if treatment isn’t necessary, it’s wise to take steps to prevent the progression of the condition. Managing blood sugar levels, maintaining healthy blood pressure, and keeping cholesterol in check can all make a difference. 

Moderate Nonproliferative Retinopathy 

Also called pre-proliferative retinopathy, moderate nonproliferative retinopathy is the second stage of the condition. At this point, blood vessels in the retina are starting to swell, altering their ability to transport blood. 

As this occurs, diabetic macular edema (DME) can develop, causing blood and fluid to build up in the macula, a specific part of the retina. As the macula swells, central vision changes typically occur. 

Severe Nonproliferative Retinopathy 

Severe nonproliferative retinopathy is the third stage of the condition. At this point, blood vessel blockages are more common and severe, preventing blood from properly reaching and moving through the retinas. Scar tissue often begins forming. Additionally, poor blood flow triggers the formation of new blood vessels, some of which may cause issues as they develop. 

If blood flow is cut off, macular ischemia occurs. Blurry vision and dark spots are both common symptoms. Also, the odds of serious and permanent vision loss are very high at this stage. While treatment may slow progression, restoring what’s lost often isn’t possible. 

Proliferative Diabetic Retinopathy 

During the fourth stage, new blood vessel growth in the retina and vitreous is increasingly common. That process is called neovascularization, and the resulting vessels are often weak, thin, and prone to bleeding. When bleeding occurs, more scar tissue forms, causing further issues. 

When the scar tissue shifts, it can pull the retina away from its position in the eye, resulting in retinal detachment. If that occurs, severe and permanent vision loss often occurs. 

Managing Diabetic Retinopathy 

If you’re at risk of diabetic retinopathy or are actively in one of the stages, working with an eye care professional is essential. They can monitor your condition and determine if treatments are necessary to slow or prevent the progression of the disease. 

At ECVA, the safety and health of our patient’s eyes are our priority. If you have signs or symptoms of diabetic retinopathy, the ECVA team is here to help. Schedule an appointment at your closest ECVA clinic today.

Cataract Treatment: Lasers vs. Traditional Cataract Surgery

cataract treatment buffalo NY

Cataracts are some of the most common eye ailments and affect millions of people all over the globe, especially older folks. For many years, cataracts were treated through traditional surgery, which involves making an incision in the cornea to remove the clouded lens. This treatment is still used to help many cataract patients today.

In recent years, technological advancements in medicine laser allowed a new type of cataract surgery to blossom: laser surgery. This type of blade-free cataract surgery is becoming more and more widely used, and it has several advantages. With that being said, traditional cataract surgery is still performed frequently and is a perfectly safe and viable procedure.

Let’s learn more about what cataracts are and about each type of treatment. Then, we’ll discuss the similarities and differences between traditional and laser cataract surgery to help you decide which method is right for you.

What are Cataracts?

The eye has a lens that helps focus light upon the back of the eye, which sends that signal to the brain for processing. This is the way that our eyes transmit an image to our brain. A cataract occurs when the lens of the eye becomes cloudy, opaque, or discolored. To a person with cataracts, the effect is similar to looking out of a cloudy window. Other symptoms include:

· Seeing halos around lights

· Sensitivity to light or glare

· Poor night vision

· Seeing colors as faded or washed-out

· Double vision

The leading cause of cataracts is simple aging – over time, it’s common for the lens of the eye to get clouded. According to the National Institutes of Health (NIH), about two in three Americans over the age of 80, and about 30 million Americans in total, have cataracts. There are other possible causes of cataracts, however, including steroid use, eye injury, and exposure to ultraviolet light. Additionally, certain diseases such as diabetes make the development of cataracts more likely. In fact, people over 65 with diabetes are twice as likely to develop cataracts as people of the same age who don’t have diabetes, according to Medical News Today.

How Are Cataracts Treated?

In some cases, treatment for cataracts isn’t necessary, particularly if the problem is only minor and the individual can still go about their daily life without much impairment. But the problem is likely to grow over time, eventually clouding more and more of the eye and affecting vision. If cataracts are left untreated, they can obscure the entire field of vision and cause complete blindness.

Eventually, cataracts will require treatment. And unfortunately, it’s not as simple as taking a pill or putting medicated eye drops into your eyes. Surgery is the best option for removing clouded lenses entirely and helping a patient get back to normal vision. There are two options: traditional cataract surgery and laser-assisted cataract surgery.

Types of Cataract Surgery: Traditional vs. Laser-Assisted

What does traditional cataract surgery involve? How about laser-assisted surgery? Let’s take a closer look at each of these types of cataract surgery options.

Traditional Cataract Surgery

Traditional surgery to remove a cataract involves using a blade to make a tiny incision on the side of the cornea (the lens) and removing the cataract-clouded lens. Then, an artificial lens known as an intraocular lens is inserted to replace the natural lens. Sutures may be used to close the incision, but it’s more common for the incision to be left to heal on its own over time.

How Long Does Traditional Cataract Surgery Take?

Traditional cataract surgery is a very quick procedure – the actual removal of the cataract-clouded lens only takes about 20 minutes or so. And the recovery period is relatively fast, too. Most people are fully healed and back to normal activities within a few days or weeks.

What is Laser-Assisted Cataract Surgery?

Laser surgery to remove a cataract lens utilizes laser technology and 3D imaging. The first step involves the surgeon creating a customized digital plan for the cataract surgery using 3D imaging of the patient’s eye. The process is “mapped” precisely ahead of time.

The procedure involves using an advanced type of laser known as a femtosecond laser to create an opening in the front layer of the lens. The laser breaks up the cloudy lens, and then the lens is suctioned out through small incisions in the patient’s cornea. Next, an intraocular lens replaces the natural lens, just like in traditional cataract surgery.

Differences Between Traditional Cataract Surgery and Laser Cataract Surgery

The result of traditional and laser cataract surgery is the same: removal of the clouded lens and replacement with an artificial one. But there are clear differences between the procedures.

Tools Used

One big difference between these two procedures is in the tools used. With traditional cataract surgery, manual instruments are used – a blade to make an incision in the cornea, and forceps or a suction tool

to remove the lens. In laser surgery, no blades or instruments are used at all. The laser itself makes the incisions and breaks up the clouded lens.

The use of fewer tools in laser cataract surgery adds to the overall safety of the procedure, and many steps in the process are automated and computer-controlled which reduces the risk of complications even further. However, traditional cataract surgery is still a very safe procedure with an extremely low risk of complications or side effects.

Accuracy

Laser cataract surgery uses 3D imaging to create a customized plan for a patient’s cataract removal. And the laser itself allows for very precise incisions and movements. In this way, laser eye surgery for cataracts is overall more accurate and precise than traditional cataract surgery.

Similarities with Traditional and Laser Cataract Surgery

As different as these two types of procedures are, they also share plenty of similarities. Namely, the two types of cataract surgery last the same length of time and are equally safe.

Duration

Whether a surgeon is using manual tools or being assisted by a laser, traditional and laser cataract surgeries are very quick procedures. The removal of the cloudy lens only takes a few minutes – 10 to 20 minutes is the average time, although it can take longer depending on the severity of the cataracts.

Safety

Both types of cataract surgery are extremely safe. It’s one of the most common medical procedures performed by ophthalmologists and eye surgeons. And the procedure is highly effective – according to UCI Health, the success rate is 99 percent.

Schedule a Consultation with the Ophthalmologists at ECVA to Determine Which Cataract Treatment is Right for You

Which cataract treatment is right for you? That depends on the severity of your cataracts, your health history and previous eye surgeries you may have undergone, and the advice of your ophthalmologist and other eye-care professionals. Both types of cataract surgery are used frequently – laser eye surgery for cataracts is generally more precise and may help lessen recovery time, but traditional cataract surgery is a perfectly viable procedure as well.

In the early stages of cataracts, treatment might not be necessary at all. Some patients are aided by different eyeglasses, magnifying glasses, or different and/or stronger lighting. But eventually, cataracts will get worse and start to affect eyesight. At that point or whenever cataracts start to affect a person’s ability to perform normal activities, surgery is usually recommended.

What is a Visual or Ocular Migraine

When people think of migraine headaches, physical discomfort or pain is usually the part that comes to mind first. However, migraines can also come with visual disturbances, and it’s even possible to have a migraine where the only symptom is a change to your vision. In either of those cases, the person is dealing with a visual migraine.  

Also known as ocular migraines, visual migraines can cause significant vision issues, making it hard – if not impossible – to navigate their environment safely. If you’re curious about visual migraines, including the different types, the symptoms you may experience, and when it’s wise to seek treatment, here’s what you need to know.  

Types of Visual Migraines and Their Symptoms  

Generally speaking, there are two types of visual migraine. First, there is migraine with aura. Here, both eyes may experience vision changes. Usually, it begins with the formation of a flickering, jagged blind spot. As the migraine continues, the blind spot can grow, generally forming a C-shape.  

Along with blind spots, a person might experience bright flashes of light or stars. The blind spots can also develop into a wide range of shapes and patterns and are often accompanied by other symptoms, including tinnitus, numbness, tingling, facial weakness, and difficulty speaking. Usually, a migraine with aura symptoms lasts between five and 60 minutes.  

The other kind of visual migraine is a retinal migraine. Generally, retinal migraines only impact one eye at a time. There may be bright flashes followed by a vision decline, including losing the ability to see out of that eye entirely.  

Usually, the symptoms of a retinal migraine last for up to 20 minutes. Additionally, they are highly intrusive while occurring, substantially altering a person’s vision to the point of having trouble navigating environments or managing everyday tasks.  

It’s important to note that vision losses can remain after a retinal migraine ends. However, this is relatively rare.  

When to Seek Treatment for Visual Migraines  

Generally, it’s best to seek treatment for all kinds of visual migraines. While a migraine with aura usually ends within an hour, the symptoms a person experiences can align with other potentially serious medical conditions. As a result, it’s best to consult with a professional to confirm a migraine is responsible.  

With retinal migraines, seeing an eye care provider is also essential. By doing so, a treatment plan can be developed, reducing the odds of long-term vision changes after episodes. Additionally, some of the symptoms of a retinal migraine are also symptoms of some serious medical conditions, such as a retinal detachment or injury. By seeking medical attention right away, you increase your odds of getting prompt treatment if another condition is causing the symptoms.  

At ECVA, the safety and health of our patient’s eyes are our priority. If you have signs or symptoms of ocular migraines and want professional insights into what you’re experiencing or haven’t seen your eye care provider in the past year, the ECVA team is here to help.

Frequently Asked Questions About Your Eyes

Many people have questions about their eyes and vision, particularly regarding visual changes, discomfort, and safety. If you’re one of them, here is a look at some frequently asked questions about eyes.  

Do Wearing Readers Make Your Eyesight Worse?  

Losing some visual acuity comes along with aging, leading many people to turn to reading glasses at some point in their 40s or 50s. However, when their vision declines further, they may wonder if the reading glasses (readers) are to blame.  

In reality, readers don’t harm your vision. Instead, any change in your visual acuity is usually natural, reflecting normal changes that can occur as you age. However, since there can be other causes for vision changes – including some serious medical conditions – it’s best to see your eye care provider to confirm whether you’re experiencing a typical vision decline or if something else is occurring.  

Can I Drive If My Eyes Are Dilated?  

When you get dilation drops, your pupils widen, causing them to take in more light. In most cases, driving home after an eye dilation is fine if you wear sunglasses to reduce the amount of light coming into the eye.  

However, every person is different, and dilating the pupils can cause blurry near vision for several hours. While the distance vision is usually unaffected, if a person’s distance vision is lacking and they’re experiencing near-vision blurriness, they may be better off having someone else drive them.  

Why Does My Vision Fluctuate?  

A significant amount of vision fluctuation can be signal a potential issue. High blood glucose levels may cause short-term changes in the lens, leading to blurriness or distortions. When the glucose levels decline, the person’s vision then clears.  

Since blood glucose fluctuations of this magnitude can be a symptom of an underlying health condition, such as diabetes or diabetic retinopathy, it’s best to see a medical professional. That way, they can determine the reason for the vision changes and create a treatment plan if needed.  

Why Do My Eyes Hurt When Working at a Computer?  

Working in front of a computer – or any other kind of screen – causes people to stop blinking as much. Since blinking is critical for keeping eyes moist, you may experience more issues with dry eye if you spend a significant amount of time in front of a computer. Dry eyes can come with a variety of symptoms, including discomfort, itchiness, and fatigue.  

Plus, depending on brightness settings, font sizes, and similar settings, you may end up with eye strain. Insufficient contrast or small fonts may make it hard to read what’s on a screen, causing a person to struggle to focus. An incredibly bright screen might be rough on the eyes, leading to squinting. In either of those cases, pain and fatigue can come with the territory.  

Generally, the best way to combat these issues is to give your eyes a break. The 20/20/20 rule can be a great place to start, ensuring you look away from the screen and at something in the distance for a minimum of 20 seconds every 20 minutes. Using eye drops can also help, ensuring your eyes remain moist, as well as adjusting your screen settings to make it more comfortable to use.

Understanding Cataract Progression

Cataracts are an incredibly common eye condition, particularly as people get older. Often, the disease progresses slowly, giving those with cataracts time to determine which course of action is best for their needs. However, there are times when cataracts can advance quickly, particularly if they’re related to an injury, illness, certain genetic conditions, environmental factors, or if they begin forming early.  

However, even if symptoms aren’t worsening quickly, that doesn’t mean treatment isn’t a necessity. If left unaddressed, cataracts can cause severe vision issues and even blindness.  

By understanding how cataracts progress, you can ensure that you receive treatment properly. Here’s an overview of the early- and late-stage symptoms, as well as guidance on when to seek treatment.  

Early-Stage Cataract Symptoms  

During the early stage of the condition, cataracts themselves tend to be small, limiting their impact on vision. Some of the more common symptoms of this stage include:  

  • Blurriness  
  • Cloudy vision  
  • Color perception changes, including dulling or the appearance that everything is covered in a yellow tint  
  • Double vision  
  • Halos  
  • Reduced night vision  
  • Light sensitivity  
  • Contrast reductions  

Needing to update your glasses or contacts prescription more frequently could also be a sign of cataracts. The same goes for requiring increasingly strong reading glasses.  

Late-Stage Cataract Symptoms  

As cataracts progress, their impact on vision is more significant. Additionally, they can cause the eye itself to turn milky white.  

Here is an overview of late-stage cataract symptoms:  

  • Milky white spot on the lens  
  • Reading difficulties  
  • Significantly decreased visual acuity  
  • Clouding over the entire lens  

When cataracts progress, the alterations to your visual capabilities have a greater impact on your daily life. You may lack the ability to see well enough to accomplish specific tasks, reducing your overall quality of life.  

When to Seek Treatment  

Generally speaking, cataracts become more challenging to treat as the condition progresses. While immediate intervention during the earliest stages may not be necessary, monitoring the cataracts’ progress is essential. That way, they can be appropriately treated once they advance to a critical point or begin having a notable impact on your quality of life.  

Delaying cataract treatment does come with risks. It can lead to significant vision loss and may cause blindness. Alterations to the lens create an increasingly dramatic colorcast over your visual field, making everything seem increasingly yellow or brown.  

Ideally, you want to work closely with your eye care provider. By keeping regular appointments, any signs of cataracts can be caught early. Then, they can track the condition’s progression, ensuring treatment can occur at the proper time. That way, the odds of permanent damage are substantially reduced, allowing you to maintain your vision long-term.
