The aim of this retrospective study is to compare the effect of a conventional incision for extra-capsular cataract extraction and intraocular lens implantation, to a non sutured small corneal incision for phacoemulsification, with implantation of foldable intraocular lenses or the wound widened to allow the insertion of a rigid intraocular lens on postoperative astigmatism. The study involved 243 patients. 189 patients were operated for extra-capsular Cataract Extraction, 54 patients underwent phacoemulsification. Uncorrected and best-corrected visual acuities were determined before surgery as well as one week and monthly for 6 months after surgery. Early significantly lower astigmatism was found in phacoemulsification group. Starting from the first postoperative month till the end of the sixth month, the astigmatism was higher in the extra-capsular group. Uncorrected and best-corrected visual acuities were better in the phacoemulsification group all through the follow up periods. Phacoemulsification results in early significant lower astigmatism, better uncorrected and corrected visual acuity, when compared to extra-capsular cataract extraction. Thus proving a better refractive advantages and early visual rehabilitation.
