摘要
目的评价准分子激光屈光性角膜切削术(PRK)的安全性、有效性、稳定性和可预测性。方法241眼(130人)行准分子激光角膜切削术以矫正近视及散光。结果术后6个月时,有90.6%的裸眼视力在0.5或以上,50%在1.0或以上;1.8%眼的最佳矫正视力下降2行或以上;80%眼的屈光状态达目标矫正值的±1.00D,55.3%达目标矫正值的±0.50D。结论 PRK 矫正近视,特别是低中度近视,具有良好的安全性,有效性稳定性和可预测性。
objective:To evaluate the safety,efficacy,stability and the predictability,of Pho- torefractive Keratectomy(PRK)was performed(for)myopia and astigmatism in 241 eyes(130 patients).Six months after operation 90.6% of eyes had the uncorrected visual acuity of 0.5 or better,50% had the uncorrected visual acuity of 1.0 or better;1.8% of eyes lost two of more lines of best-corrected visual acuity;80% of eyes were within±1.00D,and 55.3% were within± 0.50D of attempted targetcorrection excimer PRK appeared to be an effective,predictable,stable and safe method to correct myopia,especially for low and moderate myopia.
