The second advance has been post-laser suture lysis. With this procedure, sutures which are buried under the conjunctiva and which close the flap in the wall of the eye after the trabeculectomy has been performed, can be cut using a laser and a special lens. This has allowed glaucoma surgeons to make the flap tighter at the time of surgery. This prevents too much fluid leaving the eye, which can result in a number of undesirable complications, particularly a flat anterior chamber, which can be a surgical emergency. As a result of these advances, the success rate has significantly increased and the complication rate has significantly decreased.
Hemorrhage is extremely uncommon in an eye which has had no previous surgery.
Late infections of the filtration site are becoming more common with the use of antimetabolites. The safety of glaucoma surgery has increased significantly in the past few years and concomitantly, our awareness of the side effects of long-term medications has also increased. Nevertheless, if the glaucoma is uncontrolled and your visual field is getting worse, the chance of an adverse effect from surgery is less than the chance of your losing vision from glaucoma, and glaucoma surgery is generally advisable in such circumstances. Emotionally this medical condition is very draining. Not really knowing what the future may hold can be hard to deal with at certain times.
