Resident-performed Ex-PRESS shunt implantation versus trabeculectomy.

Journal Article

PURPOSE: To compare outcomes between resident-performed trabeculectomy and Ex-PRESS shunt implantation. METHODS: A consecutive cohort of 36 Ex-PRESS shunt implantations and 57 trabeculectomies (1 eye/patient) performed by resident surgeons in their third year of ophthalmic training at the University of California, San Francisco and at the San Francisco Veterans Administration Hospital, under the supervision of a single glaucoma fellowship-trained surgeon were included in this study. Eyes with < 6 months of follow-up or previous glaucoma surgery were excluded. Preoperative and postoperative intraocular pressure (IOP), preoperative and postoperative number of ocular antihypertensive medications and complication rates were compared between the 2 procedures retrospectively. RESULTS: No difference was found in postoperative IOP (all, P≥0.099) or proportional decrease in IOP (all, P≥0.092) between the trabeculectomy and Ex-PRESS shunt groups at all follow-up points. On average, the Ex-PRESS shunt group required significantly less ocular antihypertensive medication to control IOP at 3 months postoperative (P=0.01), but no difference was found at 6 months or 1 year (all, P≥0.28). A larger proportion of Ex-PRESS shunt patients had good IOP control without medication at 3 (P=0.057) and 6 months (P=0.076) postoperatively. No difference was found in the rates of sight-threatening complications between groups (all, P≥0.22). CONCLUSIONS: In the hands of ophthalmology residents in their third year of training, the trabeculectomy and Ex-PRESS shunt implantation procedures perform comparably in terms of postoperative IOP control, reduction in patient dependence on ocular antihypertensive medications, and risk of complication in our population.
