Dense membrane formation after combined phacoemulsification-trabeculectomy surgery.

A case is reported of formation of a dense intraocular membrane following combined phacoemulsification-trabeculectomy surgery. The membrane might have originated from a loose piece of pigment epithelium or might have resulted from dense pigment deposition on a postoperative pupillary membrane. Postoperative membranes have been reported particularly after combined procedures. A combination of intensive topical dexamethasone, homatropine and a Nd:YAG laser was used to speed resolution of the membrane.
