The most common complication for adults that have undergone cataract surgery is clouding of the part of the lens covering (capsule) that remains after surgery. This is known as posterior capsule opacification and may occur months of years after cataract surgery. If your vision is affected, you may opt to have a YAG laser capsulotomy to correct the problem.
For this procedure a YAG laser is used to cut a hole in the clouded back lining of the lens capsule to allow light to pass through the membrane to the retina at the back of the eye. This is done as an outpatient procedure and is painless so does not require anesthesia.
After treatment, the patient may wait for 1-2hrs after the procedure to have the pressure in their eye checked.
