Abstract:
Small incision cataract surgery using phacoemulsification, self sealing, small diameter optics and foldable intraocular lenses has been developed. These small incisions are designed to minimize the astigmatism induced by the surgery. The 3.5mm clear corneal incision for the implantation of foldable silicone lense has been widely used. However, the implantation of a PMMA lense has been tried in spite of the longer incision required for the unfoldable PMMA lense. Generally, longer incision was believed to increase the risk of infection and induced asigmatism. In this study, we analyzed the results of clear corneal incision between injectable silicone IOLs and 5mm optic PMMA IOLs. In the early postoperative period(to 3 months) vector analysis showed less induced astigmatism in the 3.5mm group than that in the 5.1mm group. The corrected visual acuity during the postoperative period was not diffrent between two groups. The posterior capsular fibrosis in 3.5mm silicone IOLs was more common than that in 5mm PMMA IOLs.
