Why Is My Vision Getting Worse After Cataract Surgery

Cataract Surgery Side Effects And How To Cope

Vision After Cataract Surgery / What’s Next? – Eye Doctor Explains

Cataract surgery is a safe procedure that improves vision for the vast majority of people. Serious complications are rare among the 4 million U.S. cataract patients who have surgery each year.

Although the recovery process is different for everyone, there are some issues that people commonly encounter in the days after surgery, as the eyes heal.

Here are 10 problems you might experience after cataract surgery, why they occur and what to do about them.

When Will My Vision Clear After Cataract Surgery

I would say that the most common questions asked after cataract surgery are:

  • What causes blurred vision after cataract surgery?
  • What can I expect after cataract surgery?
  • How long does it take for vision to clear after cataract surgery?

In this blog post, Ill try to answer these and other related questions as best I can.

Blurred vision after cataract surgery or blurry vision after cataract surgery are to be expected for at least the first day or two. Typically, your vision gets better for several weeks due to a number of factors. The factors affecting visual recovery after cataract surgery to name a few are:

  • Your age: generally a healthy 60-year-old will recover more quickly than a healthy 95-year-old.
  • Density of your cataract: a very soft mild cataract is easier to remove than a very dense cataract that has gone neglected for many years. Therefore, the swelling of your cornea
  • General health: someone with diabetes, heart disease, vascular disease, poor nutrition, alcoholism will all have a more difficult time with cataract surgery.

Why Is My Close Up Vision Worse After Cataract Surgery

The natural lens in the human eye has the ability to focus on distant as well as near objects. A person with normal vision can change focus from one object to another by changing the shape of the lens. This phenomenon is known as accommodation. The lens is able to do this because of its elasticity. The lens has a hard central core, known as the nucleus, and an outer layer, the cortex, which is much softer and more flexible.

The lens is able to do this because of its elasticity but the implanted artificial monofocal intraocular lens cannot change shape and focus on multiple distances. In fact, the intraocular lens has no elasticity. Therefore, it is unable to focus on distant objects as well as near objects. Thus, after cataract surgery, you will need glasses for near vision.

Therefore, the implantation of an artificial monofocal intraocular lens is not suitable for the patients who do not want to use glasses after cataract surgery.

What Causes A Cataract

The lens of your eye is mostly water and proteins. As proteins break down over time, they hang around in your eye. These lingering proteins can make your lens cloudy, so its hard to see clearly. This is a typical though unpleasant part of aging.

Some things can speed up the formation of cataracts, such as:

Astigmatism Does Astigmatism Get Worse After Cataract Surgery

Astigmatism is caused when the surface of the eye or the lens behind it is misshapen and not completely spherical, distorting the light that enters the eye and stopping it from focusing correctly on the retina. This, in turn, can make images look blurry.

Astigmatism is a common condition that can affect one, or both, of the eyes. It can appear in people of any age. Most people with astigmatism are either long or short sighted.

There are two types of astigmatism: regular and irregular. Regular astigmatism is the most common type and occurs when someones cornea is curved more in one direction than the other. This type of astigmatism can be easily corrected with contact lenses or glasses.

If you have irregular astigmatism, its more likely to be the result of damage caused to the cornea by some form of eye injury. This type of astigmatism occurs where the curve of the cornea isnt even. It cant always be corrected using glasses, but can sometimes be corrected with contact lenses.

Your vision is highly unlikely to get worse after cataract surgery. As you heal from your cataract surgery, you may experience scarring and fibrosis that could cause your artificial lens to move enough to induce a small amount of astigmatism. This, however, can be easily corrected after your cataract surgery, and pre-existing astigmatism doesnt get worse from the cataract surgery.

Timeline & Tips For Recovery

Schedule a ride home with a loved one after your surgery, as you will not be able to drive yourself.

When you arrive home, follow your surgeons guidelines for the first few days. This involves getting a lot of rest and protecting your eyes. You may not be able to read or use your computer for a day, but your vision should begin to clear shortly after your first eye exam.

Patient Reports Deteriorating Vision After Cataract Surgery

A 63-year-old female presented to the clinic for evaluation of reduced vision. She had undergone uneventful cataract surgery during which a +25-D three-piece acrylic intraocular lens was placed in each eye at our facility approximately 3 months previous. The refractive target for both eyes was emmetropia. As the patient did not live locally, her postoperative care was provided by her referring optometrist.

Although the recovery was reported as uneventful, with the eye healing normally, both the doctor and the patient were concerned about a poorer visual outcome than expected with the left eye. The patient described a well-healed, comfortable right eye. She was happy with the visual improvement she achieved there. The left eye, however, she described as having poor vision, which had continued to deteriorate overtime.

Her presenting acuity with an updated spectacle prescription was 20/20 OD and 20/50 OS. The glasses prescription was 0.50 D -1.00 D x 180 OD and -1.50 D -0.75 D x 175 OS. Uncorrected acuities were 20/25 OD and 20/200 OS. Pinhole testing yielded 20/20 OU visual acuity, and autorefraction showed 0.50 D -1.00 D x 168 to 20/20 OD and -2.50 D -1.00 D x 170 to 20/30 OS.

Entrance testing consisting of pupils, extraocular muscle function and confrontation fields was normal in both eyes. IOP by ICare tonometry was 12 mm Hg OU.

Follow These Five Tips To Ensure Patient Satisfaction And Avoid Undesirable Outcomes

Perhaps you didnt pay enough attention to the retina before implanting a premium IOL, got fooled by a patients masked corneal astigmatism, committed to a wound size that was too small, struggled with small pupils or made an intumescent cataract burst from an ill-advised approach. If any of these problems sound familiaror if you dont want them to become familiarfollow these five tips to steer clear of trouble.

1. Dont forget the retina.

It should go without saying that if you cant see the back of the eye, youre not going to implant a premium IOL because patients wont be happy with their vision afterward, says Kevin M. Miller, MD, Kolokotrones Chair in Ophthalmology at the University of California, Los Angeles. You also need to obtain an OCT before considering a premium IOL.

Below are some of the conditions that Dr. Miller says should rule out the use of these lenses:

vitreomacular traction

severe macular degeneration and

pigment epithelial detachments close to the center of the fovea.

Remember, also, that if youre planning to implant a premium IOL, you need to examine the retinas of both eyes, because eventually both eyes must be acceptable for the premium lens, says Dr. Miller. If you need to do regular cataract surgery, youll want to do an ultrasound to also rule out pathology in the retina, such as a mass, a tumor or a detached retina.

2. Manage cases of astigmatism realistically.

a toric IOL and/or

3. Ensure appropriate wound size.

Getting Out Of Glasses With Cataract Surgery

Many people go into cataract surgery requiring glasses and come out of it being able to see without correction!

For many, cataract surgery sharpens up the ability to see off in the distance. But reading glasses will still be required to see up close. The distance vision becomes exceptionally sharp if astigmatism is also corrected at the time of cataract surgery with lasers or with special premium toric lenses .

However there are two ways cataract surgery can be used to get out of glasses for mostly everything .

  • Monovision . With this technique, one eye is corrected during cataract surgery to sharpen up the distance vision. This eye by itself wont be able to see up close, so the other eye is corrected for computer and reading vision. Between both eyes, the full range of vision is covered. Typically it may take a month or more to fully adjust to monovision.
  • Premium or lifestyle artificial lenses such as trifocal lenses. Instead of having the eyes perform separate tasks, a special lens is used which allows for each eye to see the full range of vision. These particular lenses work best for healthy eyes and do come with some night-time vision symptoms to adjust to over time.

These two methods both have their pros and their cons. Ultimately the preferred approach is tailored to each persons visual needs and demands. A discussion with your cataract surgeon will determine the optimal way to correct your vision the best after cataract surgery.

Faqs About Cataract Surgery Healing

When does blurriness go away after surgery?

Blurry vision after cataract surgery will go away gradually, but you should have some visual clarity the day after the operation. Within about two weeks, you should be able to see fairly well, and after a month, you should have good, clear vision. If vision problems persist, or blurriness comes and goes, talk to your optometrist during an eye exam. When can you exercise after surgery?

Your optometrist will clear you to return to an exercise routine within two to three weeks after surgery. However, you may only be able to moderately exercise. If you prefer more strenuous exercise or contact sports, you should wait for one to two months after the surgery. Can I watch TV or movies after surgery?

Since you will spend a lot of time resting after surgery, you might want to watch television or movies to occupy your time. While your vision may be blurry for a few days after surgery, and you want to avoid straining your eyes during this time, you can watch a show or movie after about 24 to 48 hours.

Immediately after surgery, you should not look at anything. Plan to sleep or relax with your eyes closed instead.

My First Thoughts After Surgery

Because of the medication I had been given, I dont remember being in the recovery area for the obligatory 10 to 15 minutes. But my memory vividly restarts at the point where I was sitting in the chair in the discharge area.

From the discharge area, I could see the holding and recovery areas. Through my right eye, these areas were definitely bright. With my left eye closed, I could see everyone walking around and I easily could recognize them.

Distant images were still blurry. Unfortunately, I decided to look down at my identification wrist band and noticed that the Charles Slonim name was crystal clear.

Oh @$#%& , I thought. Now Im myopic ! I have the wrong implant power. Someone made a mistake!

I was agitated. I did not want to be myopic after cataract surgery. I had been emmetropic my entire life. I wondered whether I should say something now, or just wait. I was a doctor myself, after all, and I had to get this straightened out.

Would I need another procedure? I hoped not.

I tried to recall everything I could about clear corneal cataract surgery, the type of procedure I had undergone. I reminded myself that corneal edema or swelling typically induces a myopic shift until it resolves.

I decided I would wait to say anything, although on the way home I continued to fret about the possibility of a less than optimum visual outcome. But on the positive side, and while I was busy second-guessing my surgeon, I did notice the color contrasts in the distance were amazing.

What If My Vision Is Still Blurry Even After Cataract Surgery

If youve had cataract surgery and your vision is still blurry or hazy, you may have a common condition called posterior capsule opacification . PCO, also sometimes called a secondary cataract, occurs when the capsule that holds the IOL in place gets obstructed by epithelial cells from the lens.

This causes blurry vision and glare at night, much like the symptoms of having a cataract. The good news is that PCO is easy to treat with a procedure called a YAG Laser Capsulotomy.

During a YAG Laser Capsulotomy, a laser creates a central opening in the hazy capsule, which allows light to pass through it. This then takes care of any blurry vision and lets you finally see clearly after cataract surgery!

PCO can develop anywhere between a few weeks to several years after cataract surgery, but a YAG Laser Capsulotomy is typically not performed until at least three months after the initial cataract surgery to ensure that the eye has fully healed.

Floaters And Flashes Of Light

Surgery can cause posterior vitreous detachment, where the vitreous separates from the retina. It makes you see moving spider webs and clouds in your vision, along with flashes of light.

Usually, it gets better on its own within a few months. Because the symptoms are similar to retinal detachment, call your doctor right away to get checked out.

Eyeglasses Recommended By Cataract Surgeons

Before you have cataract surgery, your ophthalmologist will discuss your options for glasses following surgery. There is no best option for post-surgery glasses, as everyones needs and requirements are different. Cataract surgeons recommend being patient and waiting for your eyes to fully heal before being fitted for a new pair of glasses.

Virtually any brand of eyeglasses will work provided the prescription is correct. Most eye doctors recommend that you wait at least one month following cataract surgery before getting a new prescription. This is to ensure your vision has stabilized.

Because most IOLs used in cataract surgery can only provide clear distance or clear near vision, you will need glasses to correct for whatever the lens doesnt provide. Usually, just one lens in your glasses needs to be updated for the eye that was operated on.

As long as your frames fit the updated lens, you may not need to make a big change to your eyeglasses. The important thing that ophthalmologists stress is to select the intraocular lens and subsequent glasses based on your personal lifestyle and vision priorities.

The Importance Of Managing Complications

With all complications, including capsular rupture and vitreous loss, and even endophthalmitis, the prognosis is better if the complication is managed effectively. Not every patient who suffers capsular rupture and vitreous loss experiences a poor outcome. If the complication is managed well, it is possible for the patient to retain excellent vision. However, we often do not deal with vitreous loss as well as we should. The article on page 6 provides top tips from experienced cataract surgeons for managing vitreous loss. In the case of endophthalmitis, early recognition and prompt treatment with intravitreal vancomycin and either ceftazidime or amikacin seems to offer the best hope of visual recovery. With immediate use of intravitreal antibiotics, some eyes will recover useful vision.

The management of complications needs to be incorporated into training programmes. For example, management of vitreous loss, like every other surgical skill, can only be learnt by practicing under the supervision of a more experienced surgeon. However, although vitreous loss is most likely to occur while the surgeon is inexperienced, when it does occur, the trainer will usually take over. This means that, in some developed countries, ophthalmologists may do a few hundred cataract operations during their training, but will only manage vitreous loss two or three times.

The Definition Of Cataracts

Cataracts are an age-related condition, often affecting people over the age of 55. In most cases, when cataracts do begin to develop, they affect both eyes. It is possible for your vision to seem worse in one eye than the other.

A cataract is a clumping of proteins in the eye. When an eye is healthy, these proteins get spread out. When cataracts form, proteins gather in the center of the eye. It may take several years for symptoms to appear after a cataract has developed.

When symptoms do start to affect you, surgery is not the first step. Early symptoms are treatable with prescription eyeglasses. When your vision becomes too obstructed for daily activities, its time for the next step. The only way to permanently treat cataracts is with cataract surgery.

Although you can slow down their development, cataracts are not preventable. With cataract surgery, your natural lens gets replaced with an IOL.
