目的：评价准分子激光屈光性角膜切削术（ＰＲＫ）治疗轻、中度近视眼的临床效果。方法：对在我院接受ＰＲＫ治疗的８１只轻、中度近视及近视散光眼的术后半年随访结果进行统计分析。结果：术前近视度（等值球镜）范围为－１．００～－６．００Ｄ，其中轻度近视占１６．０％，中度近视占８４．０％，单纯近视占５６．８％，复性近视散光占４３．２％。术后半年裸眼视力≥１．０者占７４．１％，≥０．８者占８８．９％，≥０．５者占９２．６％。剩余屈光度≤±０．５Ｄ者占８４．０％，≤－１．０Ｄ者占９５．１％。剩余屈光度的均数及标准差为－（０．３３±０．３８）Ｄ。角膜上皮下混浊情况：０级占６０．５％，１／２＋占３５．８％，＋占３．７％。无角膜感染、角膜疤痕、复发性角膜糜烂、过矫及不规则散光等并发症发生。结论：ＰＲＫ治疗轻、中度近视眼预测性及稳定性好、安全有效。远期效果有待继续随访。
Objective: To evaluate the clinical effect of excimer laser refractive keratectomy (PRK) in the treatment of mild to moderate myopia. Methods: Sixty-one follow-up outcomes of 81 mild to moderate myopia and myopic astigmatism patients receiving PRK in our hospital were analyzed statistically. Results: The preoperative myopia (spherical equivalent) ranged from -1.00 to -6.00 D, of which mild myopia accounted for 16.0%, moderate myopia 84.0%, simple myopia 56.8% , Refraction myopic astigmatism accounted for 43.2%. Six months after surgery, the uncorrected visual acuity ≥1.0 accounted for 74.1%, ≥0.8 accounted for 88.9%, ≥0.5 accounted for 92.6%. Remaining diopter ≤ ± 0.5D accounted for 84.0%, ≤-1.0D who accounted for 95.1%. The mean and standard deviation of the remaining refraction was - (0.33 ± 0.38) D. Corneal epithelial opacities: 0 level 60.5%, 1/2 + 35.8%, + 3.7%. No corneal infection, corneal scar, recurrent corneal erosion, overcorrection and irregular astigmatism and other complications. Conclusion: PRK treatment of mild to moderate myopia predictability and good stability, safe and effective. Long-term results to be continued follow-up.
