PRECIS: We describe standardization and simplification of classic trabeculectomy combined with manual small incision cataract surgery (MSICS) to effectively manage the 2 leading and often coexisting causes of blindness and vision impairment in resource-constrained areas. PURPOSE: The purpose of this study was to describe modifications to trabeculectomy combined with MSICS and report on the outcomes of this technique. The modifications consist of standardization and simplification of the surgical steps. METHODS: Data obtained from adult patients who underwent described surgical technique at rural eye care centers across 3 Indian states between January 2018 and May 2019 were analyzed retrospectively. Complete success was intraocular pressure between 6 and 18 mm Hg without supplementary medication. Qualified success allowed up to 3 topical medication(s). Data are presented as median (first and third quartiles). RESULTS: We analyzed data of 70 eyes of 70 patients. Ophthalmology fellows performed 27 (38.5%) surgeries, whereas an experienced glaucoma specialist performed 43 (61.4%) surgeries. Patients were 63 (56, 67) years old. The preoperative intraocular pressure was 20 (16, 26) mm Hg on treatment with 3 (2, 3) antiglaucoma medications. Glaucoma was advanced by optic disc structural criteria in 58 (82.8%) eyes. Intraoperative mitomycin C was used in 5 (7.1%) eyes. Follow-up was 12.5 (6, 18) months. At 1 year, complete success (95% confidence interval) achieved was 55% (41-67), whereas qualified success was 83% (68-92) with 0 (0, 1) topical medications. The complete and qualified success rates did not differ between ophthalmology fellows and the glaucoma specialist (P=0.75 and 0.44, respectively). CONCLUSIONS: We present a straightforward, yet effective technique of combined cataract and glaucoma surgery. The technique has a potential for wider applicability, especially in the underserved regions of the world.
