Corneal Incision Phacoemulsification and Trabeculectomy: combined Surgery at Separated site

ABSTRACT

We reviewed 9 eyes which underwent combined phacoemulsification and trabeculectomy at separate site. Phacoemulsification was performed using corneal incision and trabeculectomy was performed at one superior quadrant using a limbus-based conjunctival flap with mitomycin C(0.2mg/ml, 3-5 minutes). Six eyes received 3-piece folable silicone lenses and 3 eyes received 1-picec PMMA(diameter 5.5mm) lenses. Mean preoperatie intraocular pressure (IOP) was 23.4+/-8.7mmHg. Mean follow-up period was 12.7(range 6-21)months. The mean postoperative IOP at 1, 6, 12 months were 14.6+/-4.8mmHg, 13.8+/-4.4mmHg, 16.6+/-6.8mmHg, respectively. Seven eyes achieved a final fisual acuity of 0.7 or better. One patient developed vision-impairing complications; flat anterior chambe and anterior dislocation of silicone lens. Other complications include posteror synechiae(4 eyes), capsular opacities (3 eyes), lens decentration with capsular contracture(1 eye). These rusults suggest that combined corneal incision phacoemulsification and trabeculectomy at separate site offers an effective technique to control postoperative intraocular pressure in patients with coexsisting cataract and glaucoma, though this procedure is not devoid of complications.
