After cataract surgery patients can develop what is described as a “film” or cloudiness of vision, this is called PCO (Posterior Capsule Opacification) . This occurs when scar tissue builds up around the implant lens from cataract surgery. A YAG (Yttrium Aluminum Garnet) laser capsulotomy is a procedure that uses a laser to break up the scar tissue. This procedure is quick and painless. The body will naturally absorb the pieces of scar tissue and vision will start to improve.
A PCO (Posterior Capsule Opacification) will develop in approximately 50% of patients post cataract surgery. There is no telling when or if a patient might develop a PCO, but it is easily treated without anesthesia, pain or restrictions.
