This is a cloudy membrane that forms on the back surface of an implant lens inside the eye after cataract surgery. This opacity can form months or years after a successful cataract operation and can cause blur and glare symptoms (similar to the original cataract). These “after cataracts” are not a complication from cataract surgery, but rather a continued proliferation of tissue inside the eye (similar to scar tissue). After-cataracts are easy to treat with a laser. A YAG capsulotomy can be performed to create a hole through the opaque membrane. This is a simple, painless procedure, and once performed the “after cataract” does not typically reoccur.
