Abstract
Introduction: the two conditions that cause blindness and that can frequently coexist in the same patient are glaucoma and cataract. Cataract surgery plus trabeculectomy is very useful in Latin American countries due to its good visual results and low cost for patients with limited economic resources. Being a cost-effective alternative for this type of population.
Objective: to describe the results of small incision cataract surgery combined with trabeculectomy in patients with glaucoma refractory to maximum therapy at Fundación Visión.
Methodology: a retrospective observational study was carried out that included patients who underwent combined cataract and glaucoma surgery at Fundación Visión from May 2021 to April 30, 2022. The following variables were analyzed; visual acuity, intraocular pressure (IOP), number of hypotensive medications, pre and post surgery, in addition to operative complications.
Results: before surgery, 51 % of patients had an IOP between 21 to 30 mmHg, and 57 % used triple drug therapy. After surgery, 98 % of patients had IOP <20 mmHg and 41 % did not need to use hypotensive medications. IOP was significantly reduced (p <0.001) from 28.59 mmHg pre-surgery to 11.18 mmHg post-surgery. In 41% of patients (n = 21) the success was complete, in 57% (n = 29) the success was partial and in one patient there was no success. There was only one case of intraoperative complication with zonulodialysis and the postoperative complications were choroidal detachment and flat bulla, with two cases each.
Conclusion: small-incision cataract surgery combined with trabeculectomy is a safe, effective, and lower-cost treatment for people suffering from cataract and glaucoma.
