All surgical procedures have risks. Glaucoma surgery is no different. The primary risks include, but are not limited to, infection, bleeding, swelling in the retina, development of fluid under the retina (choroidal detachment), retinal detachment, droopy eyelid, double vision, loss of vision, and even loss of the eye. The likelihood of these risks is quite low, but you should discuss the risks, as well as the benefits of the procedure, with your surgeon. In general, if your eye surgeon recommends a glaucoma filter procedure for you, he or she believes that the potential benefits of the procedure far outweigh the potential risks.
