Cataract surgery is one of the most common and successful procedures performed today, often restoring clear vision within days. However, for some patients, cloudy vision may return after the initial surgery. This is usually due to a condition called Posterior Capsule Opacification (PCO), sometimes referred to as a “secondary cataract.” The good news is that this cloudiness can be quickly and effectively treated with a YAG laser capsulotomy - a short, painless procedure that restores clarity almost immediately.

During cataract surgery, your natural cloudy lens is removed and replaced with a clear artificial intraocular lens (IOL). The new lens is placed inside a thin, transparent membrane called the posterior capsule.

Over time, cells left behind from the original lens can grow on the capsule, causing it to thicken or become cloudy. This blurriness can mimic the symptoms of cataracts, such as glare, hazy vision, and reduced clarity, especially in bright light.

A YAG laser capsulotomy is a quick, outpatient procedure used to remove the cloudy portion of the capsule that forms behind the lens implant.

During the procedure:

• Your ophthalmologist uses a YAG laser to create a small, precise opening in the capsule.

• This allows light to pass through clearly again, restoring crisp, bright vision.

• The entire process usually takes only a few minutes and requires no incisions or stitches.

Most patients notice improvement in their vision within hours, with minimal discomfort or downtime.

In most cases, ophthalmologists recommend waiting at least three months after cataract surgery before performing a YAG laser capsulotomy. This waiting period allows the eye to fully heal and ensures the intraocular lens has stabilized in its final position.

However, the exact timing can vary depending on:

• How quickly PCO develops

• Your eye’s healing response

• The level of visual symptoms (such as glare or blur)

Some people may develop PCO within a few months, while others may not experience it until years later. Dr. Ahdoot will determine the appropriate timing based on your individual healing and vision changes.
