What's the difference between discission and cataract surgery?
Cataract surgery is a removal of the cloudy lens (one that has become less transparent) in the eye. Modern cataract surgery usually includes leaving the original "skin" of the back surface of the eye’s natural lens (called the "posterior capsule") in place in an effort to better support a plastic artificial intraocular lens ("implant") that replaces the cataract. In some cases, this capsule becomes cloudy, and a discission—creating an opening in the capsule so that light can better pass through it—can be made. This is usually accomplished with a laser and is called a "posterior capsulotomy."
