The Change of Astigmatism After Cataract Extraction with Double Horizontal Suture

Abstract

We analysed a series of cataract surgery cases into two groups. double horizontal suture group and shoelaces running suture group. We modified horizontal suture technique putting two separate sutures before opening the anterior chamber. Shoelaces running suture group showed early with-the-rule astigmatism about 2 diopter, which decayed over time reaching breakout point at 8 weeks, then very little change. Double horizontal suture group also showed early with-the-rule astigmatism, but the amount was less than half a diopter, which decayed over time, reaching break point at 4 yveek, stabilizing thereafter. After 8 weeks there was no statistical difference between two groups. In summary, double horizontal suture results in less astigmatism and therefore better visual acuity immediatedly after the surgery (p<0.005, student t-test) and for the first 2 months compared to shoelaces running suture.
