Abstract

Since surgically induced corneal astigmatism was one of important complications after cataract extraction the authors analyzed corneal astigmatism for 3 months after sutureless cataract surgery. Among the patients who were treated with phacoemulsification and PCL implantation by one surgeon (L. E. H.), 40 patients had sutureless cataract surgery by 5mm incision and 51 patients had 10-0 nylon shoelace suture by 7mm incision. Corneal astigmatism was analyzed by algebraic and vector method. Visual acuity was analyzed in patients who were below 60 years age and without posterior segment disorders, whose predictive refractive errors were -0.75D according to SRK/T formula. 0.19D with-the-rule astigmatism induced at 1 day after 5mm sutureless cataract surgery was nearly unchanged until 3 months postoperatively and induced with-the-rule astigmat ism at 1 day after operation was not changed into against-the-rule astigmatism, visual rehabilitation was faster and corrected visual acuity was better.
