One-year results of hyperopic photorefractive keratectomy (HPRK) at Cedars-Sinai Medical Center

摘要

The preliminary results of hyperopic photorefractive keratectomy (HPRK) performed with the VISX-Star excimer laser on 40 eyes of 25 patients are presented. 28 of 40 eyes had vision of 20/40 at 6 months and 22 of 25 eyes saw 20/40 12 months postoperatively. Eleven of 40 patients were over corrected 1.00 D at 6 months and no patients were overcorrected with the same amount at 12 months postop. At six months, no undercorrections of 1.00 D were observed and 3 of 25 eyes were undercorrected by 1.00 D at 12 months postop. At 6 months postop, 35 of 40 eyes saw for near J5 or better, and 20 of 25 saw J5 at 12 months postop. Complications included: induced astigmatism of 1.00 D (6 of 40 eyes at 6 months and 3 of 25 eyes at 12 months), and loss of two lines of best corrected vision (4 of 40 at 6 month,s and 2 of 25 at 12 months). HPRK appears to be safe and effective in correcting hyperopia of up to 4.00 D in the short to medium term.
