YAG Laser Capsulotomy

What Is YAG Laser Capsulotomy?

Following surgery to remove cataracts, there is risk of a condition referred to as posterior capsule opacification. If this occurs, YAG laser capsulotomy is the only treatment option. This issue is considered to be the most common cataract surgery complication.

When you have surgery for cataracts, your doctor removes the natural lens and replaces it with an artificial one. This eliminates the clouding that affected your natural lens. The lens capsule of your eye is where the new artificial lens goes. It remains clear after you have cataract surgery.

After surgery, the cells that are still there will grow back at the back of the capsule. They can become opaque and thickened. This reduces light’s ability to get to the retina, resulting in vision that is cloudy or blurry. Some people experience issues with glare and bright lights.

Overall, the vision problems associated with this complication are similar to those experienced when you have cataracts.

It is possible to develop this complication in both eyes if you had cataracts removed from both of your eyes. It is possible for each eye to develop the issue at different times.

This complication is common, but certain factors may increase your risk of developing it. If you have cataracts removed at a younger age, your risk of this complication is higher. It also tends to develop more in people with certain other eye issues, such as retinitis pigmentosa.

How Effective Is This Procedure?

YAG laser capsulotomy can be done quickly, and it often offers immediate improvement in your symptoms. It has a 95 percent success rate.

An assessment of the potential for retinal detachment five months after the operation was 0.87 percent.

It is important to find a doctor who has experience with this procedure to give yourself the lowest risk of complications and the greatest chance of success.

Results have been similar in studies on children. After a single procedure, 70 percent of the participants in one study maintained clear vision. This study also showed that complications were infrequent.

The Procedure

There is little preparation necessary for YAG laser capsulotomy. You will not have to worry about things like changing into a surgical gown or fasting.

  • The retina can detach, causing the appearance of floaters. If this happens, it needs to be reported immediately to your doctor.
  • The artificial lens may work its way through the opening in the posterior capsule.
  • There is a risk of eye pressure increasing.
  • Some people experience swelling in their eye. If this occurs, steroid drops are usually prescribed.
