Outcome of manual small incision cataract surgery in patients with pseudoexfoliation syndrome and pseudoexfoliation glaucoma

Abstract

Purpose: The study aimed to analyze the surgical outcome of manual small incision cataract surgery (MSICS) in patients with pseudoexfoliation syndrome (PXF) and pseudoexfoliation glaucoma (PXG) and compare them with those of controls. Settings and Design: This prospective, observational, and comparative study included 150 cases of PXF with cataracts, 150 cases of PXG with cataracts, and 200 cases of cataracts without PXF as controls. Methods: MSICS was performed in all cases under peribulbar anesthesia. Intraoperative complications, if any, were noted. Best-corrected visual acuity (BCVA), intraocular pressure (IOP), and postoperative complications were recorded at follow-up on day 1, day 7, and after 1 month. Statistical Analysis Used: IBM SPSS 24.0 statistics, SPSS South Asia Pvt Ltd. Results: Lines of improvement in BCVA were significantly better in the control group (8.7 ± 1.7) than that in the PXF (7.5 ± 2.1) and PXG groups (6.4 ± 2.7). IOP significantly decreased from baseline to 1 month postoperatively in the PXG group than in the PXF and control groups (mean difference: 3.8 ± 7.5 mm Hg). Intraoperative iridodialysis and zonular dialysis were significantly high in the PXG group with a proportion of 4 and 20%, respectively. Postoperative choroidal detachment and hyphema, six cases each, were found significantly high in the PXG group. Conclusion: Although the BCVA improvement was less and the complications were high in patients with pseudoexfoliation, especially those with PXG, the reduction in IOP was significant. MSICS can be considered favorably in patients with PXF and PXG, with adequate precautions to manage anticipated complications.
