Cirugía combinada de facoemulsificación y trabeculectomía por dos vías con y sin mitomicina C

Abstract

Purpose: To evaluate the effectiveness of «two-ports» combined phacoemulsification and trabeculectomy surgery with and without mitomycin C. Material and Methods: A prospective study of 28 eyes of 28 patients with coexisting cataract and chronic glaucoma who underwent combined surgical procedure of phacoemulsification and trabeculectomy with two different ports, has been carried out. 15 of these eyes had the combined surgery alone, and the others 13 eyes had the combined surgery plus an intraoperative 2 minutes application of a 0.2 mg/ml mitomycin-C (MMC) solution. The mean follow-up period has been 11.6 months (min.: 6, max.: 18) for the without-MMC group, and 11.5 months (min.: 6, max.: 18) for the with-MMC group. Results: At the last follow-up visit, 11 of 15 cases (73.3%) of the without-MMC group and 9 of 13 cases (69.2%) of the with-MMC group, reached a final IOP <20 mmHg and >5 mmHg. At the same visit, 9 of 15 cases (60%) in the without-MMC group and 8 of 13 cases (61.5%) in the with-MMC group had a final best-corrected visual acuity of 0.5 or better. So, no clinically significant difference in postoperative pressure reduction and visual acuity was seen between the groups. Complications were minor and similar in both groups, except one case of assymptomatic hypotony developed in each group. Conclusion: Intraoperative application of MMC in «two-ports» combined phacoemulsification and trabeculectomy surgery, does not seem to increase the success rate of this surgical procedure by its own.
