Abstract :

 A prospective randomized comparative study was carried out in 100 cases of senile cataract. All the patients underwent MSICS under peribulbar anesthesia. 50 cases received straight scleral incision and 50 cases received frown  scleral incision. Postoperative astigmatism was studied in both groups using Bausch & Lomb keratometer on day 1,5,15,30 and 90. After 3  months of surgery, out of 50 patients in straight scleral incision group 86% patients had ATR astigmatism, 10% had WTR astigmatism and  4% had OA whereas in frown incision group 82% of the patients had ATR astigmatism, 14% had WTR astigmatism and 6% had OA. Mean  surgically induced astigmatism in frown incision group(0.90 D) was significantly less than the straight incision group(1.09D) after 3 months  postoperatively. This study reveals that there is reduction in magnitude of postoperative astigmatism as well as surgically induced astigmatism in frown incision than straight incision in MSICS resulting in better postoperative visual acuity
