PURPOSE: To compare the results of two-site phacotrabeculectomy with microincision cataract surgery (MICS) and trabeculectomy. METHODS: Fifty-eight eyes with coexisting cataract and glaucoma were randomly assigned to have a trabeculectomy in a superior quadrant combined with phacoemulsification and intraocular lens (IOL) implantation through temporal clear corneal incision (two-site phacotrabeculectomy group), or a trabeculectomy in a superior quadrant combined with MICS followed by IOL implantation from the trabeculectomy incision (MICS + trabeculectomy group). The main outcome measures were preoperative and postoperative intraocular pressure (IOP), number of glaucoma medications, best-corrected visual acuity (BCVA), and complications. Follow-up was period was 12 months. RESULTS: Twenty-eight two-site phacotrabeculectomies and 30 MICS + trabeculectomies were performed. Mean age of the subjects was 67.4 years. Mean preoperative IOP was 24.6±5.7 mmHg in the two-site phacotrabeculectomy group and 23.7±5.5 mmHg in the MICS + trabeculectomy group (p=0.52). At 12 months postoperatively mean IOP was 14.5±3.0 and 14.3±3.4 mmHg in two-site phacotrabeculectomy and MICS + trabeculectomy groups, respectively (p=0.8). Preoperative and postoperative glaucoma medication numbers were similar and mean number of glaucoma medications decreased in both groups after the surgery (p<0.05). BCVA improved in both groups. Twenty-six of 28 eyes (92%) in the two-site + trabeculectomy group and 27 of 30 (90%) in the MICS + trabeculectomy group had clinically apparent filtering blebs at 12 months (p=0.71). Postoperative complications were comparable. CONCLUSIONS: MICS + trabeculectomy provided 1 year IOP control comparable to that with two-site phacotrabeculectomy with similar amount of complications and similar final BCVA.
