Purpose: To study the changes in ocular surface disease index and tear film tests for evaluation of dry eye among patients who have undergone cataract surgery. Methods: A total of 123 patients aged more than 40 years undergoing cataract extraction were included. 87 of them underwent manual Small Incision Cataract Surgery(SICS) and 36 underwent Phacoemulsification(Phaco). Dry eye symptoms were evaluated using OSDI(Ocular Surface Disease Index) questionnaire, tear film assessment was done using Schirmer__ampersandsignrsquo;s test 1, TBUT(Tear Film Break up Time) at baseline and 6 weeks after surgery. Relevant statistical tests were used to evaluate the significance of the variables. Results: The overall incidence of dry eye using OSDI score was 29.26%, with mean OSDI scores of 13.85__ampersandsignplusmn;9.83 and 23.12__ampersandsignplusmn;14.54, pre and post-operative respectively a difference in score of 9.234 and significant P value (__ampersandsignlt;0.001). Out of 55 dry eye positive subjects 49(89.09%) had mild symptoms and 6(10.9%) had moderate symptoms. Incidence using tear film tests such as schirmer__ampersandsign#39;s test 1 was found to be 12.19% and TBUT was found to be 24.39%. All dry eye test values were significantly impaired at 6 weeks of post cataract extraction. Conclusion: Incidence of dry eye after cataract surgery was 29.26%. Cataract surgery is capable of causing and aggravating dry eye. TBUT and OSDI scores indicated more cases of dry eye postoperatively compared to the Schirmer__ampersandsign#39;s test 1 scores. Thus TBUT and symptom scores are better indicators for assessing dry eye.
