Purpose: To compare the results of combined phacotrabeculectomy by means of a one-site versus two-site approach. Materials and methods: A retrospective study has been performed over 35 glaucomatous patients with a coexisting cataract, treated with a one-site (19 cases) or a two-site (16 cases) phacotrabeculectomy. First, effectiveness of both procedures has been proved by statisticly analysing the IOP and visual acuity changes after surgery. Normal distribution, homogeneity and homocedasticity from both groups have been checked. Finally, visual acuity and 6-month postoperatively IOP among both groups have been compared by means of a «mean difference t Student test for independent samples». Results: No statistical differences among both procedures have been found (p>0.05). Also, postoperative complications were similar among groups. Conclusions: Combined trabeculectomy and phacoemulsification surgery is a useful treatment for glaucomatous patients with coexisting cataract, and provides good visual and ocular-pressure results. One-site and two-site surgical approachs provide the same six-month follow-up results.
