A new triple surgery procedure was applied to 20 primary open-angle glaucomatous (POAG) eyes. This technique comprises trabeculotomy with narrow (2-3 mm) fornix-based scleral flap, combined with extracapsular cataract extraction (ECCE) and posterior chamber intraocular lens (PC-IOL) implantation. As to surgical results, at two years postsurgery 53% (9/17) of the eyes were controlled under 21 mm Hg without medication, 35% (6/17) with topical medication alone. Eighteen (90%) eyes showed improved visual acuity of two or more Snellen lines. No serious postoperative complications occurred. There was no significant difference in postoperative astigmatism as compared with ordinary ECCE and PC-IOL surgery. Trabeculotomy with fornix-based scleral flap offers the advantage of simple and safe surgery when combined with ECCE and PC-IOL implantation.
