If medical therapy for glaucoma is ineffective at halting the ongoing damage to the optic nerve and loss of vision, your eye doctor may recommend glaucoma surgery. There are many different types of surgery for glaucoma. Each one of them is performed in order to lower intraocular pressure. By lowering intraocular pressure, it is hoped that optic nerve damage and loss of vision can be halted. Often, incisional surgery is recommended after attempts with medications or laser are unsuccessful. During incisional surgery, your ophthalmologist makes tiny cuts, also known as incisions, into the outer layers of the eye with a tiny knife while looking through a microscope. The goal of incisional glaucoma surgery is to create a small passage for fluid from within the eye to pass unimpeded into the outer layers of the eye. In a sense, this channel bypasses the trabecular meshwork, which is the tiny drain within the eye which is impaired in glaucoma. When successful, this lowers intraocular pressure and preserves vision. | Home
