Roughly 20% of patients will develop a posterior capsule opacity (PCO), also known as a secondary cataract. Although it is sometimes called a secondary cataract, it is not a cataract. Once Dr. Dudee removes your cataract, it is gone forever. A PCO occurs when the posterior portion of the capsule becomes hazy following cataract surgery. Thankfully, there is a very simple procedure used to remove it called a YAG laser capsulotomy. It can be performed in our office and only takes a few minutes to complete. After a patient undergoes a capsulotomy, they can immediately resume normal activities. It is common to have floaters for a short term following your YAG laser treatment.
