Abstract
Abstract Background: Surgically induced astigmatism is that the reason for poor postoperative vision even after uneventful cataract surgery. Aim: The aim of study is to check the incidence, degree, type, and course of surgically induced astigmatism and visual sense in temporal 3.5-mm clear corneal phacoemulsification and 6-mm superior scleral incision in Small incision cataract surgery (SICS) at Tripoli medical center. Materials and Methods: A total of 200 eyes of 200 patients with a mean age of 62 years were included within the study. Cases were randomly divided into two groups. group A had undergone 3.5-mm temporal clear corneal phacoemulsification and blood type had undergone 6-mm superior scleral SICS. Surgically induced astigmatism was analyzed by SIA software. Results: Mean age in A was 61 (±8) years and in group B was 63 (±10) years. Mean surgically induced astigmatism in blood group was 1.05 (±0.58) D, 1.13 (±0.52) D, 1.13 (±0.56) D, and 1.08 (±0.52) D on 1st, 7th, 21th , and 45th postoperative days, respectively. The change from 1st to 45th day wasn't significant. the identical in blood group was 0.75 (±0.58) D, 0.81 (±0.54) D, 0.88 (±0.49) D, and 0.91 (±0.47) D 1st, 7th , 21th, and 45th postoperative days, respectively. Surgically induced astigmatism was comparable on all days between the groups. We found significant with the rule and against the rule form of astigmatism post-operatively within the temporal clear corneal incision in phacoemulsification group and in superior scleral incision in small incision cataract surgery group respectively. Conclusion: Surgically induced astigmatism was higher within the superior scleral group than in 3.5-mm temporal clear corneal group. Clinical outcome of both surgeries was same, as there was no significant difference within the uncorrected postoperative acuity in between the groups.
