After Cataract Surgery Blurry Vision

Swelling Of The Cornea

How long is your vision blurry or cloudy after cataract surgery? – Dr. Sriram Ramalingam

On the opposite side of the epithelium on the cornea is another small layer of cells called endothelium. These cells have one role: pump extra water out of the cornea.

The cornea sits right next to water . Thus, these cells are constantly working to pump out extra water that makes its way into the cornea.

Extra water that gets into the cornea can cause it to swell. This swelling will alter the transparent structures of the cornea causing things to be more cloudy. This swelling will also change the way the cornea focuses light also causing things to be a little more blurry.

During cataract surgery two things happen.

  • Through a process called phacoemulsification, a special instrument uses ultrasound waves to break up the cataract. These ultrasound waves if applied close to unprotected endothelial cells can “stun” or even damage those endothelial cells and prevent them from pumping water out of the cornea.
  • Because the eye is a liquid-based environment, cataract surgery is performed completely “under water” so to speak. Because a tiny vacuum is used, water that is removed must be replaced with new water via irrigation. Sometimes this irrigation can push extra water into the cornea causing more swelling. .

Between extra water pushed into the cornea and the endothelial cells becoming impaired, swelling can build up in the cornea.

How Long Does It Take For The Eye To Heal Fully After Cataract Surgery The Longer Term

The consensus seems to be that it takes 1-3 months. So you should expect your eyes to have stabilized 2-4 months after the surgery. Youll probably have another Ophthalmologist appointment around that time.

Thats when you should be ready to have your eyes tested and be given a new glasses prescription if needed.

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:

  • Eye surgery or eye injuries.
  • Radiation treatment to your upper body.
  • Spending a lot of time in the sun without eye protection, like sunglasses.

Blurred Vision Months After Cataract Surgery


I am devastated. I had cataract surgery on 9/11/15, and around December I started to have blurred vision. It is now June 1, 2016, and it starts every time I look at my phone, computer, or even read a magazine. I got computer glasses, and they enlarge the words, but when I put my regular glasses on everything is blurred. No really the large things, but everything I read, etc. I knew I would wear glasses, so that is not my problem. No eye diseases, have seen the surgeon and another neuro opthamologist. No one seems worried, or to take me seriously. I work a 40 hour job that I love, but as soon as I turn on my computer at work, there goes the blurred vision. It lasts all day and does not go away until about 2 hours after I get home. There is a problem, but no one seems to know what it is. They said the lens are in place, etc., and all looks good. It is not. Has this ever happened to anyone else? Before my surgery, I had worked for 12 years on the same computer I have now, and loved to read. I can’t even read our newspaper, as my vision blurrs up. Also, on the TV Guide, after I get home from work and still have the blurred vision, the guide shows like a ghost shadow on the bottom of the words on the guide! Help!!!

    It sounds like you might have what’s called PCO cynthia . Your cataract surgeon can fix it with a laser treatment. Get a second opinion from another doctor and ask them if they think you have it.

  • Vision After Cataract Surgery

    Generally vision after cataract surgery is superb. With cataract surgery, the wonderful thing is that we can generally put an artificial lens in your eyes that not only replaces your cloudy natural lens, but it potentially allows you to see clearly without any glasses for distance and near objects. Multifocal lenses are now available that are just amazing. They have a built in bifocal that allows you to see distant objects clearly and near objects as well. The lens does not require you to move your head at all. You just see clearly. They are amazing and have improved drastically in the past five years with newer models allowing a bigger range of vision. They are sometimes called EDOF which stands for extended depth of field. This allows you to see objects at nearly any distance without difficulty.

    Is It Normal To Have Blurred Vision After Cataract Surgery

    Yes, blurred vision is normal after cataract surgery. It takes time for your eyes to heal and to adjust to the new lens that has been implanted.

    Not everyone will recover from cataract surgery at the same pace. Some people may have clear vision within a day after having cataract surgery. But for other people it may take several days for blurred vision to go away.

    If you still have blurry vision several weeks after your cataract surgery, follow up with your ophthalmologist to rule out potential complications.

    Although its common to experience blurred vision after cataract surgery, it usually clears up within several days. If your blurred vision continues, it could be due to a variety of factors. Lets look at these in more detail.

    What Can I Expect During Recovery From Cataract Surgery

    Laser Precision Restores Vision after Cataracts

    Although it can take up to four to eight weeks to fully recover from cataract surgery, most people will notice their vision begin to improve much sooner, and typically there should little pain or discomfort during this period. Youll have some follow-up appointments with your provider during this time. About 9 out of 10 people see better after cataract surgery.

    During the days and weeks that follow surgery, follow your providers instructions to:

    • Use eyedrops as directed.
    • Use your eye shield, pad and eyeglasses.
    • Read, watch TV and use the computer as usual.
    • Use sunglasses when going outside.
    • Resume your activities and routine.


    • Use eye makeup for one week.
    • Drive until your provider gives you the all-clear.
    • Swim for two weeks after surgery.
    • Fly without getting the all-clear from your provider.

    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.

    How To Clean Your Eye

    • Boil some water and allow it to cool.
    • Wash your hands.
    • Dip cotton wool or clean gauze in the cool boiled water.
    • Gently wipe from the inside to the outside corner of your eye.
    • Do not wipe inside your eye.
    • Do not wash your eye out with water.
    • Do not press on your eye.

    During the first 2 weeks, you may need to clean your eye twice a day because the drops and the healing process can cause slight stickiness.

    How Does Cataract Surgery Work

    Diagnostic Eye Center is proud to offer our patients laser cataract surgery, which is the most state-of-the-art technology available for cataract surgery. Laser cataract surgery uses the LenSx Laser, which replaces many of the steps that had to be done by hand during traditional cataract surgery. It also removes the use of any blades and increases precision, allowing patients to achieve the best possible results. During cataract surgery, youll receive a mild oral or IV sedation to relax before the procedure, followed by numbing eye drops.

    After the eye drops have completely spread over the surface of the eye, your Diagnostic Eye Center surgeon will use the LenSx femtosecond laser. The laser creates small incisions at the front of the eye and makes a small opening in the capsule.

    This opening gives your surgeon access to the cataract. Removing the cataract involves a procedure called phacoemulsification. During phacoemulsification, an ultrasonic probe is used to dissolve the cataract.

    After dissolving the cataract, an intraocular lens is then placed into the eye to take the place of the natural lens. The IOL is what allows you to see clearly after cataract surgery!

    Cataract is unpreventable but can be regulated. A surgery here would involve replacing the natural eye lens with an IOL. At initial stages, you can support the loss in eyesight with eyeglasses. But, if the vision seems clogged to an extent where you struggle completing your daily tasks, surgery by experienced surgeons is the way to go.

    What Causes Cloudiness In The Eye After Cataract Surgery

    Everyones eyes are equipped with a lens — much like a camera — thats responsible for focusing light rays that pass through it. Once those light rays reach the retina in the back of the eye, it eventually gets converted into an image with help from the brain. This gives us vision.

    When youre born, this lens is generally crystal clear. Itll remain clear for most of your life, which is why were able to see so clearly without blurred vision, faded colors, or hazy images. Without this clear lens, your entire view of the world will change drastically — literally.

    The Wrong Design Of The Implanted Lens

    Before cataract surgery, the ophthalmologist speaks to you about the various options you have when it comes to the lenses. Some of them have blue light filters others produce a clear image in only one distance while other lenses enable you to see far and near but in most cases with slight drawbacks when it comes to image clarity.

    Multifocal lens implants usually produce a slightly less clear visual experience in regards to the contrast and lead to more glare at night. Halo effects are also common. Usually, doctors test the lens design before cataract surgery with contact lenses. This way they see if glare for example is a problem for you.

    But in some cases, this does not turn out as planned. This means the patient reacts sensitive to glare and is not satisfied with the visual acuity. In such a case another surgery needs to be done in which the lenses or one lens gets changed into a monofocal lens design. This way the drawbacks like halos or glare disappear.

    Blurred Vision After Cataract Surgery Possible Causes

    Especially after cataract surgery patients expect to see clearer with new transparent lenses inside their eyes compared to the cloudy one before surgery. But this unfortunately is not always thus surgery turns out. In seldom cases, patients see more blurred after cataract surgery than they did before. When the visual acuity is worse than before surgery even after 4-5 weeks the causes could be plenty.

    • Malpositioned lens implant
    • Insertion of the wrong intraocular lens implant
    • Inaccurate measurements
    • Unstable position of the intra ocular lens implant in the capsular bag
    • Corneal complications after cataract surgery
    • Retinal complications after cataract surgery
    • Drooping eyelid
    • Wrong design of implanted lens

    Unclouded vision is the goal of lens treatment to correct cataracts. Patients who suffered severely from the cloudy lens before treatment, in particular, are understandably very much looking forward to the experience of being able to see clearly and sharply again with their own eyes. All the greater the disappointment when the blurred vision persists after cataract surgery.

    What Are The Different Types Of Cataract Surgery

    There are two types of procedures to remove cataracts:

    Phacoemulsification cataract surgery

    Phacoemulsification is the most common procedure for cataracts. Your ophthalmologist makes a small opening in the eye to reach the clouded lens. Using high-frequency sound waves or a laser, your ophthalmologist breaks the lens into pieces. Then the doctor suctions lens fragments from your eye and puts in a new plastic lens.

    Extracapsular cataract surgery

    Your doctor might recommend this procedure if the phacoemulsification technique isnt a good option for you. For example, an advanced cataract might be too dense to break apart easily.

    In extracapsular cataract surgery, your ophthalmologist makes a larger opening in the eye. Instead of breaking up the lens and then removing it, your doctor removes the lens in one piece. Then the surgeon inserts the manufactured lens.

    Blurred Vision 2 Years After Cataract Surgery Causes & Home Remedies

    Approximately 9.5 million cataract surgeries are performed worldwide every year. This makes cataract surgery one of the most frequently performed surgeries. Usually, most people opt to go for a cataract surgery when they experience extreme blurry vision. The main purpose of the cataract surgery is to correct blurred vision. However, in some cases, months or years after the surgery, the patient may experience a blurred vision once again. This is known as a SECONDARY CATARACT.

    What Is Posterior Capsular Opacification

    How long will I have blurry vision and glare after cataract surgery ...

    You may notice that your vision becomes cloudy or blurry after your cataract surgery even months or years after the procedure. Providers call this posterior capsular opacification, or PCO, and its normal. Its also called a secondary cataract.

    PCO happens because a membrane called the posterior capsule becomes cloudy. The posterior capsule once held your eyes lens and now holds the intraocular lens in place.

    If your vision starts to blur again, you may need a posterior capsulotomy to restore your vision. A laser makes an opening in the cloudy capsule. This procedure can give you clearer vision again.
