Khan L; Verma SIndian Journal of Ophthalmology 2022; 70: 3918-3922
PURPOSE: To explore straight incision technique in terms of efficacy for intraocular pressure (IOP) lowering by small-incision cataract surgery (SICS) trab versus modified "frown" incision with triangular scleral flap technique. METHODS: This study was done at a tertiary health center. It included 44 eyes diagnosed with cataract and coexisting primary glaucoma that underwent SICS with trabeculectomy using modified "frown" incision with triangular scleral flap technique and straight incision in group A (n = 22) and B (n = 22), respectively. Postoperative evaluation was done at first postoperative day, then at the end of first week, third week, and 6 weeks; at the end of third month and finally at the end of sixth months. Data were entered and analyzed via Microsoft Excel sheet and SPSS software using Mann-Whitney U test for averages and Chi-square test for categorical values. RESULTS: Mean preoperative IOP in groups A and B were 38.6 and 29.1 mm Hg respectively, by applanation tonometry. After 6-month follow-up, mean of difference in IOP (preoperative - postoperative) for group A was 20.8 ± 8.3 mm Hg and that for group B was 17.2 ± 13.5 mm Hg. CONCLUSION: Capacity of IOP reduction of both techniques was found to be comparable and did not show much difference up to the end of 6 months. Mastering technique of group A (modified "frown" incision with triangular scleral flap technique) requires more expertise; the simpler straight incision technique provided in group B may be effectively used by the novice and current era Ophthalmologists to combat glaucoma coexistant with cataract.
