Abstract
Purpose: To compare the changes in intraocular pressure (IOP) before and after cataract extraction using noncontact tonometer (NCT) in small incision cataract surgery (SICS) and phacoemulsification. Materials and Methods: A prospective observational study of 100 eyes that underwent phacoemulsification and 100 eyes that underwent SICS with intraocular lens implantation for senile cataract with normal IOP were included. Both groups underwent IOP recording using NCT, preoperatively, postoperatively at the 1st, 4th, and 6th weeks, respectively. Repeated-measure analysis of variance and independent sample t-test were applied to analyze the data. Results: The mean IOP at the preoperative and postoperative 1st, 4th, and 6th weeks was 13.07, 12.24, 11.78, and 11.66 mmHg, respectively, in SICS group and 14.39, 13.94, 13.08, and 12.90 mmHg in phacoemulsification groups, respectively (P < 0.001). Conclusion: A decline in postoperative IOP was present in both SICS and phacoemulsification groups, but a more significant decline was noticed in SICS group.
