| Abstract;We performed photoastigmatic refractive keratectomy (PARK) on 25 astigmatic eyes of 20 patients after cataract surgery with intraocular lens implantation. The astigmatism averaged 3.64.+-.1.23 diopters (D) before and 1.08.+-.0.64D 6 months after PARK. The difference was significant (p<0.0001). The time course of changes in postoperative astigmatism was stable during the 6 months of follow up. PARK induced a hyperoptic shift by approximately 2D. Uncorrected visual acuity also improved significantly. Best corrected visual acuity showed transient deterioration during the immediate postsurgical period to promptly recover to the preoperative levlel. The achieved astigmatic correction was within.+-.1.0D of the target value in 64% of eyes. Major complications were consistently absent including severe haze or persistent corneal epithelial defect. The findings show the safety and effectiveness of PARK for astigmatism in pseudophakic eyes. (author abst.) |
