Infection and bleeding are risks of any surgery. Scarring can cause the drainage to stop. One-third of trabeculectomy patients will develop cataracts.

Other Information
Trabeculectomy is a surgical procedure used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye's trabecular meshwork and adjacent structures. It is the most common glaucoma surgery performed and allows drainage of aqueous humor from within the eye to underneath the conjunctiva where it is absorbed. This outpatient procedure is most commonly performed under monitored anesthesia care in a half awake state using a retrobulbar block or a combination of topical and subtenon (Tenon's capsule) anesthesia.
Other Information
Approximately 56% of all patients achieve results of 20/20 or better and over 90% achieve 20/40 or better (which is good enough to drive without corrective lenses in most regions).1 Those with moderate to high myopia (greater than 7 diopters) have a lesser chance of achieving that result. As technique and technology improve, the results continue to improve.
