Can lenses after cataract surgery be replaced?
Cataract surgery can be redone, most commonly after a problem occurs with the lens implant from the original procedure. Cataract surgery entails removing the natural lens material and replacing it with an artificial lens implant designed to match the patient's approximate prescription.
As the eye's natural lens is removed and then replaced with an artificial one, it is not possible for a cataract to develop again. The proteins inside your eye cannot clump together in an artificial lens as it is made from a specialist plastic material.
To fix it, you need a procedure called YAG laser capsulotomy. Your doctor uses a laser to create a hole in the back of the lens capsule. That lets light pass through so you can see normally.
Cataract surgery cannot be reversed, since the cloudy natural lens of the eye is removed during a cataract procedure and cannot be put back in.
Cataract surgery improves your vision by removing the lens and replacing it with an IOL. But it's not always a one-and-done deal. While it's true that cataracts don't “grow back” over time, you may develop a secondary cataract after the surgery.
In clinical practice, it is a common observation among ophthalmic surgeons that patients with bilateral cataract often report more pain and discomfort during the second consecutive eye surgery.
Sometimes blurry vision is caused by PCO, a fairly common complication that can occur weeks, months or (more frequently) years after cataract surgery. It happens when the lens capsule, the membrane that holds your new, intraocular lens in place, becomes hazy or wrinkled and starts to cloud vision.
- A sudden decrease in vision.
- Redness in or around the eye that persists after two days.
- Continued sensitivity to light.
- Discharge from the eye.
- Pain that continues.
- Fever, nausea or vomiting.
- Sudden increase in floaters, or flashing lights.
In general, poor vision after cataract surgery is caused by: inadequate correction of post-operative refractive error (lack of spectacles); failure to detect pre-existing eye conditions, e.g. macular degeneration or amblyopia (selection); or surgical complications (surgery).
If you have cloudy vision after your cataract surgery, we can use laser treatment to safely, effectively, and painlessly correct it. This procedure, known as a YAG laser capsulotomy, allows light to clearly pass through the pupil into the eye. With this procedure, your vision is restored in a matter of hours.
What are the side effects of secondary cataract surgery?
Possible complications include an increase in pressure in the eye (boosting the risk for glaucoma), inflammation of the eye that requires steroid eyedrops, or detachment of the retina.
The simple answer is that they're intended to be permanent, but some complications can arise that may require additional surgery or treatment. When the eye's natural lens is replaced with an artificial lens, the fear of cataracts forming on the new lens is eliminated – in that sense, the results are permanent.

In some cases, cataract surgery may not be effective, and you may continue to have vision problems or worse vision after surgery. This is rare, but it's more common in people who had other eye conditions beyond cataracts even before surgery.
Among patients who rated second-eye surgery as generally more negative than first-eye surgery, 47.83% thought their vision would be better in the second eye than the first and 3.48% thought their vision would be worse (P < . 05); 48.7% thought their vision would be the same.
After performing the first of two clear corneal cataract surgeries on a patient, many providers typically complete the second eye in a delayed sequential fashion, waiting one week to one month to allow time for healing.
It is a general practice to wait for at least a week, or a minimum of 4-5 days, before performing the surgery on the second eye.
Patients with a dislocated IOL may experience a decrease or change in vision, diplopia, and/or glare. Additionally, they may report ocular pain or headaches from intermittent angle-closure and/or inflammation. Some patients also report seeing the edge of the IOL.
How are secondary cataracts treated? The only treatment to eradicate secondary cataracts is a YAG laser capsulotomy. The YAG laser capsulotomy is a simple outpatient procedure and is completed in a clinic in as little as a few minutes.
A secondary cataract, also known posterior capsule opacifcation, is the most common complication after cataract surgery. It happens in 3-50% of cases five years after cataract surgery, and is a result of the migration and proliferation of the epithelial cells that lead to reduced visual acuity.
This procedure is performed using traditional surgical techniques or lasers. Cataract surgery is usually an outpatient procedure, covered under Medicare Part B. Once you pay the annual Part B deductible, which is $233 in 2022, you're responsible for the Part B coinsurance.
Can you have lens replacement surgery more than once?
Our answer is yes. If there is an issue with your IOL, it can be replaced with another one. This usually occurs when the lens does not provide adequate vision correction or causes problems like double vision. However, patients should keep in mind that the need for revision is rare.
- You may lose vision. ...
- You may develop debilitating visual symptoms. ...
- You may need additional eye surgery to reposition, replace or remove the phakic lens implant. ...
- You may be under treated or over treated. ...
- You may develop increased intraocular pressure. ...
- Your cornea may become cloudy. ...
- You may develop a cataract.
Unlike natural lenses, IOLs do not break down over a person's lifetime and do not need to be replaced. It is possible to exchange implants if necessary.
Immediately following cataract surgery, it is, in fact, normal to have blurry vision. Many patients are back to their regular activities the day after cataract surgery. This applies to most activities except for driving.
Part of the tissue covering the lens (the capsule) is left to help hold the IOL in place. Overt time, this capsule can become cloudy, leading to blurred vision and PCO. Blurry vision caused by PCO can occur weeks, months, or even years after you have cataract surgery.
You'll be happy to know that not only is cataract surgery nearly painless with a quick recovery process, but it also has a very high success rate — 97-98% according to recent studies. This is because it is a common surgery that involves very few (if any) possible complications.
If there is progression to pain, decrease in vision, or any discharge from the eye, patients are advised to seek medical attention. A long-term consequence of cataract surgery is posterior capsular opacification (PCO). PCO is the most common complication of cataract surgery.
No, your vision generally doesn't deteriorate after cataract surgery unless other problems arise, such as macular degeneration or glaucoma. In cataract surgery, the eye doctor (ophthalmologist) removes the clouded lens from your eye and replaces it with a clear, artificial lens.
The main difference between cataract surgery and Refractive Lens Exchange (RLE) is that cataract surgery is used to actually remove the cloudy lens on the eye and RLE is used to minimize the use of glasses or contacts after the procedure.
Who is not suitable for lens replacement surgery? Lens replacement can correct issues with vision such as short-sightedness (myopia), long- sightedness (hyperopia), presbyopia, cataracts and astigmatism. If you are not affected by any of these conditions, lens replacement surgery is probably not suitable for you.
