目的：评价准分子激光屈光性角膜切削术（ＰＲＫ）治疗轻、中、高度近视眼的临床效果。方法：对在我院接受ＰＲＫ治疗的２３９只近视眼的术后２年随访结果进行统计分析结果：Ⅰ组术前近视－１．００～－６．００Ｄ（等值球境，下同），术后２年裸眼视力≥１．０者占８７．１％，≥０．５者占９７．０％，剩余屈光度为－０．３４±０．３９Ｄ，９５．０％，角膜已完全恢复透明；Ⅱ组术前近视－６．２５～－１２．００Ｄ，术后２年裸眼视力≥１．０者占４７．８％，≥０．５者占８８．４％，剩余屈光度为－０．７７±０．６３Ｄ，７８．２％角膜已完全恢复透明。结论：ＰＲＫ治疗－１２．００Ｄ以下，特别是－６．００Ｄ以下近视眼安全有效，预测性及稳定性好
Objective: To evaluate the clinical effect of excimer laser photorefractive keratectomy (PRK) in the treatment of mild, moderate and high myopia. Methods: The results of 2-year follow-up of 239 myopia patients treated with PRK in our hospital were statistically analyzed. Results: The preoperative myopia of -1.00 ~ -6.00D (equivalent sphere, the same below) 2 years after uncorrected visual acuity ≥1.0 accounted for 87.1%, ≥0.5 accounted for 97.0%, the remaining power was -0.34 ± 0.39D, 95.0%, the cornea has been completely restored to the transparent ; Group Ⅱ preoperative myopia -6.25 ~ -12.00D, 2 years after uncorrected visual acuity ≥ 1.0 accounted for 47.8%, ≥ 0.5 accounted for 88.4%, the remaining power was -0. 77 ± 0.63D, 78.2% The cornea has fully recovered and transparent. Conclusions: PRK is safe, effective, predictable and stable in myopia of less than -12.00D, especially -6.00D
