Ocular Surface Changes After Cataract Surgery: Assessing Dry Eye Disease And Tear Film Instability

Abstract

Objective: To evaluate ocular surface changes and dry eye disease (DED) following cataract surgery,

comparing outcomes between Small Incision Cataract Surgery (SICS) and Phacoemulsification(Phaco).
Methods: A prospective cohort study was conducted on 70 patients undergoing cataract surgery at Greater Siliguri Lions Eye Hospital from January to March 2024. Pre- and post-operative assessments included OSDI, TBUT, keratometry, and visual acuity.

Results: Significant postoperative improvements were observed in OSDI scores, BCVA, and near visual acuity

in both surgical groups. A mild but significant decline in TBUT was noted postoperatively in both SICS and Phaco groups. No significant intergroup differences were found in postoperative OSDI, TBUT, or visual acuity.

Conclusion: Both SICS and Phacoemulsification result in transient tear film instability but yield comparable visual and ocular surface outcomes. With proper management, cataract surgery does not significantly compromise long-term ocular surface health.
