Can Cataracts Return After a Premium Intraocular Lens Is Implanted?
Yazar: Op. Dr. Gökay Günay
One of the questions most frequently asked by people considering premium intraocular lens treatment or cataract surgery is:
“Can cataracts come back after a premium intraocular lens is implanted?”
The short answer:
No.
A cataract develops when the eye’s natural lens gradually loses its transparency and becomes cloudy.
During cataract surgery or premium intraocular lens treatment, this natural lens is removed and replaced with an artificial intraocular lens.
Because the natural lens is no longer present in the eye, a cataract cannot develop again in the same eye.
Why Do Cataracts Not Come Back?
A cataract forms in the eye’s natural lens.
Because this lens is removed during surgery, the tissue in which a cataract could develop is also removed.
For this reason, after successful cataract surgery, a true cataract cannot form a second time in the same eye.
Why Do Some Patients Say, “My Cataract Came Back”?
In most cases, this refers to a different condition.
In some patients, the thin capsule behind the intraocular lens may become cloudy months or years after surgery.
This condition is called:
Posterior Capsule Opacification
or
Secondary Cataract
These terms are used to describe this condition.
Although it is commonly described as “the cataract coming back,” it is not a true cataract.
What Is Posterior Capsule Opacification?
During cataract surgery, the capsular structure that supports the intraocular lens is preserved.
In some patients, this capsule may become cloudy over time and cause symptoms such as:
- Blurred vision
- Light scatter
- Reduced quality of vision
- Reduced contrast
These symptoms may sometimes resemble those of a cataract.
How Is Secondary Cataract Treated?
Posterior capsule opacification can generally be treated with a brief laser procedure.
During this procedure, called YAG laser capsulotomy, a small opening is created in the cloudy capsule.
The procedure usually takes only a few minutes and does not require stitches or another operation.
Many patients notice a clear improvement in quality of vision within a short time.
Can the Same Condition Occur with Premium Lenses?
Yes.
Posterior capsule opacification may occur not only after standard cataract surgery, but also with multifocal lenses, EDOF lenses and other premium intraocular lenses.
This does not mean that the lens has deteriorated or stopped functioning.
The problem occurs in the capsule tissue behind the lens, not in the lens itself.
Does the Premium Intraocular Lens Need to Be Replaced?
No.
When posterior capsule opacification develops, lens replacement is generally not necessary.
In most cases, laser treatment is sufficient.
Conclusion
Once a premium intraocular lens has been implanted, a true cataract does not form again in the same eye.
However, some patients may develop clouding of the posterior capsule over time. Although this is sometimes described as “the cataract coming back,” it is not a true cataract.
This condition can generally be treated with a brief laser procedure, and many patients experience an improvement in quality of vision afterwards.
