Abstract: 
fiogf49gjkf0dPurpose: To compare postoperative astigmatism-results of suture less 3.2 mm clear corneal (SSC) and 5.5 mm scleral (SSS) incision in phacoemulsification cataract surgery.Methods: This semiexperimental study was performed on 100 eyes of97 patients.Phacoemulsifcation cataract surgery was performed with foldable acrylic lens implantation with 3.2 mm clear corneal incision (70 cases) and small optic P.M.M.A lens implantation with 5.5 mm scleral incision (30 cases). Both incisions were made in superior vertical meridian and keratometric alterations were recorded preoperatively, and 5 days and 3 months after surgery. Comparisons were made with T test and simple subtraction and polar-value methods.Results: In the SSC group, mean astigmatism increased from 0.81 D (dioptre) preoperatively to 1.44 D at 5 days and 1.06 D at 3 months after surgery. It equals to 0.25 D increase in astigmatism 3 months after surgery. In the SSS group, mean astigmatism increased from 1.09 D to 1.12 D at 5 days after surgery and reduced to 1.02 D at 3 months after operation. In other words, there was 0.07 D reduction in mean corneal astigmatism 3 months after surgery. The number of eyes with W.T.R astigmatism decreased from 46 cases before surgery to 15 cases after that and the number of eyes with A.T.R astigmatism increased from 29 cases before surgery to 60 cases after the operation.Conclusion: No significant difference was observed between SSC and SSS incisions regardingsurgically induced astigmatism and the amount of surgically induced astigmatism was very low in both groups. Thus we recommend SSC incision fur easy phaco cataract surgery.
