Complications of cataract surgery can sometimes be avoided by using a special stain on the membrane surrounding the cataract.
Most people who undergo cataract surgery enjoy great vision that had been elusive to them for years. But not all people are lucky in this matter. For some, the biggest obstacle to complete recovery is a condition called cystoid macular edema or CME. This is one of the main reasons for delayed recovery of vision, and in a few patients, the cause for permanent vision damage.
