Purpose: The aim of the study was to analyze the effect of cataract surgery on ocular hypertension and to evaluate if type of surgery changes the postoperative intraocular pressure (IOP) outcome. Materials and Methods: A prospective longitudinal study of sixty patients out of which forty of them underwent phacoemulsification and twenty underwent manual small incision cataract surgery over a period of 2 years from December 2014 to October 2016. Data were entered in Microsoft Excel and analyzed using Strata version 13. We calculated the means and standard deviations for the linear variables and proportions for the categorical variables. The means between two groups were compared using the unpaired t-test (for different groups). The proportions were compared using Chi-square test or Fisher's exact test (for low expected cell counts). We used Mann–Whitney test for comparing the distribution of the variables and Wilcoxon matched-pairs signed-ranks test for equality of matched pairs. Conclusion: In our study, 22.7% fall is noted by the end of 3 months. Pressure-to-depth (IOP/anterior chamber depth) ratio is a valuable prognostic indicator in ocular hypertensives as well to predict postoperative IOP outcome. The type of surgery did not effect the reduction in IOP postsurgery by the end of 3 months.
