- Abstract
Background: Cataract surgery is aimed at providing early visual rehabilitation and good vision. MSICS has added advantage over phacoemulsification of being done in every cataract type along with being cost-effective, stable, consistent, successful in visual recovery, safe, less technology-dependent, short-duration, and sutureless. Aim: The present study was conducted to comparatively evaluate astigmatism induced surgically following Blumenthal versus Frown corneoscleral tunnel incision in MSICS. Methods: The study included 88 subjects from both genders divided into 2 groups of 44 subjects each via odd and even numbers where Group A subjects underwent MSICS with Blumenthal Corneoscleral incision and Group B subjects with Frown Corneoscleral incision. Follow-up of all subjects was done at 1 day, 1, 4, and 6 weeks postoperatively where the assessment was done with Keratometry, fundoscopy, slit-lamp biomicroscopy and vision. Results: Mean best-corrected visual acuity was higher in Group B (Frown incision) compared to Group A with Blumenthal incision with respective values of 0.630±0.210 and 0.691±0.229. However, this difference was statistically non-significant with p=0.199. In the group, The mean astigmatism was continuously increasing till the 3rd week and then it decreased. But there were no statistically significant differences were found between different time intervals (P=0.453). In group B it was gradually increasing till 3rd week and after 6th week it slightly reduced. A statistically significant difference was found between time intervals (P=0.026). Mean visual acuity, preoperatively, was statistically non-significant between the two groups with respective values of 0.191±0.408 and 0.123±0.136 respectively for Group A and B (p=0.297). On postoperative day1, 1st week, 3rd week, and 6th week the visual acuity between the two groups was statistically non-significant with respective pvalues of 0.402, 0.387, 0.227, and 0.087 Conclusion: The present study concludes that in MSICS, both Frown and Blumenthal corneoscleral incisions have minimal astigmatism and best-corrected visual acuity postoperatively. However, surgically induced astigmatism has a non-significant difference in the two study groups. Hence, both the incisions can be used for cataract management;however, the Blumenthal incision is better for big nuclei and hard cataracts compared to the Frown incision.
