Abstract Details


To compare the result of Phaco Trabeculectomy with Trabeculectomy in the surgical treatment of glaucoma in a 5 years retrospective study.


Cases were performed at Centro Laser, Dominican Republic.


In a comparative retrospective case series study, 107 patients underwent phacotrabeculectomy and 42 underwent trabeculectomy alone. Post-operative best corrected visual acuity (BCVA), post-operative medication, pre-operative and post-operative IOP, bleb grading and complications were compared through follow-up. Patients with previous ocular surgery were excluded from the study. All the patients were intervened by the same surgeon under topical anesthesia with the use of MMC 0.4% during 3 minutes.


The mean IOP in the preoperative period was 23mmHg in patients who underwent Phaco trabeculectomy and 24 mmHg in those who were subjected to trabeculectomy. In the postoperative follow-up, both procedures showed a reduction of IOP, 51.0% of patients with Phaco trabeculectomy reported pressures ≤ 10 mmHg and 61.1% of those submitted to Trabeculectomy achieved pressures to the same extent. Regarding the use of glaucoma treatment, both groups showed a significant difference in its reduction. Successful blebs at 5 years occurred in 90% of Phaco Trabeculectomy group and 93% in Trabeculectomy alone.


There was no significant difference on the bleb appearance, success and IOP values when the Trabeculectomy was performed alone or in combination with Phacoemulsification procedure. The study demonstrates that combined surgery will provide identical results in the control of glaucoma as the Trabeculectomy alone.
