准分子激光原位角膜磨镶术治疗高度近视

目的评价准分子激光原位角膜磨镶术治疗高度近视的疗效。方法采用LASIK治疗高度近视186例308眼，按术前屈光度将患者分为2组。对1a随访结果进行统计分析。结果A组术前近视-6.0～-10.0D(等值球镜，下同)术后1a裸眼视力达到0.5和1.0者分别为95.76%和77.58%，剩余屈光度为-0.32D±0.46D。B组术前近视-10.25～-20.00D，术后1a裸眼视力达0.5和1.0者分别为62.24%和37.06%.剩余屈光度-0.92D±1.13D。结论LASIK治疗高度近视安全有效，并有较好的预测性和稳定性。

Excimer laser in situ keratomileusis for treatment of high myopia

Objective　To evaluate the effects of the excimer laser in situ keratomileusis (LASIK) for treatment of high myopia.Methods　LASIK was performed on 308 eyes of 186 patients who were followed up for one year. The patients were divided into two groups (group A and group B) according to preoperative diopters.Results　One year after surgery, in group A(-6.0～-10.0D) the uncorrected visual acuities of 0.5 and 1.0 were in 95.76% and 77.58% of the eyes, the mean residual refraction was -0.32D±0.46D. In group B(-10.25～-20.0D) the uncorrected visual acuities of 0.5 and 1.0 were in 62.24% and 37.06% of the eyes, the mean residual refraction was -0.92D±1.13D.Conclusion　It is an effective and safe refraction surgery to correct high myopia with LASIK.
