Abstract
Abstract A method and device which is used to insert an implant in order for treating an eye with glaucoma in order to lower the intraocular pressure of the eye. The implant is an artificial meshwork. The implant is attached to a guide knife which is inserted into the anterior chamber of the eye. The knife is then removed leaving the implant in place. During the operation, a prismatic lens with c-shaped vacuum ring is used to help assist the surgeon in viewing the anterior chamber of the eye and stabilizing the eye.
