摘　　要：目的探讨LASIK治疗高度及超高度近视术后屈光回退的相关因素。方法选择接受LASIK治疗的高度和超高度近视患者47例(93眼),其中男18例(35眼)、女29例(58眼)。按术前屈光度不同分A、B2组,A组为高度近视(-6.00^-9.00D)30例(59眼),B组为超高度近视(-9·25^-14.00D)17例(34眼)。分别记录术前与术后1个月、3个月、6个月视力、屈光度、角膜中央厚度和眼轴长度。结果术后6个月A组正常眼54眼,回退5眼;B组正常眼22眼,回退12眼,2组之间屈光回退率差别具有显著性(χ2=10.39,P<0.05);回退的患者多伴有角膜中央厚度增加(82·4%);A、B2组LASIK术后屈光回退均与年龄、性别以及眼轴长度变化无关。结论LASIK术后屈光回退与术前屈光度的高低和术后角膜中央厚度增加有关,而与年龄、性别以及术后眼轴长度的变化无关。Objective To evaluate the regression relevant factors of LASIK for treatment on high and over-high myopia. Methods The prospective study involved 47 patients （93 eyes） with high and overhigh myopia who received LASIK treatment, 18 male （35 eyes）,29 female（58 eyes）. They were divided into two groups according to preoperative diopters ： Group A high myopia（ -6.00～-9.00 D in 59 eyes）and group B over-high myopia（ -9.25～-14.00 D in 34 eyes）. The follow-up time was 6 months,and the visual acuity, refractive diopter, central corneal thickness and the ocular axis length were collected and analyzed at preoperation, 1 month, 3 months and 6 months after operation, respectively. Results Within 6 months after LASIK, there were 5 regressive eyes in the group A and 12 eyes in the group B （X^2=10.39, P 〈 0.05）. The regression eyes were often accompanied by the increased thinkness of central corneal （83.4% ）. Both in group A and B, the age, gender and ocular axis length were not related to regression. Conclusion The preoperative refraction and the central corneal thickness are related to post-operation regression in contrast to age,gender and ocular axis length.
