LASEK治疗高度及超高度近视的临床观察

Clinical observation on LASEK for treatment of high and super-high myopia

目的:评价LASEK治疗高度、超高度近视的临床效果。方法:回顾2008-07/2010-01在我院行LASEK手术的271例493眼患者,按术前等值屈光度分为高度近视组(6.00～10.00D)与超高度近视组(≥10.00D),其中高度组311眼,超高度组182眼。随访1a,比较术后两组的裸眼视力、haze及其它并发症。结果:术后裸眼视力均较术前提高。随访结束,裸眼视力≥术前最佳矫正视力(BCVA)眼数为,高度组255眼(82.0%),超高度组110眼(60.4%),两者统计有显著性差异(P<0.01)。术后haze均在2级之内;无明显的角膜刺激症状及严重并发症出现。结论:LASEK治疗高度近视安全、有效,但对超高度近视的治疗效果不佳。

AIM：To evaluate the clinical results of laser subepithelial keratomileusis （LASEK） in the correction of high and super-high myopia.METHODS：LASEK was performed on 271 cases（493 eyes） with myopia who were divided into a high myopia group（6.00-10.00D） and a super-high myopia group（≥10.00D） on the basis of the preoperative spherical equivalent refraction.The high myopia group was 311 eyes and the other group was 182 eyes.The follow-up time was 1 year.The postoperative uncorrected visual acuity（UCVA）,haze and other complications were compared between the two groups.RESULTS：The postoperative UCVA raised in all eyes.At the end of 1 year,there were 255 eyes （82.0%） in high myopia group and 110 eyes （60.4%） in the other one of which the postoperative UCVA was better than the preoperative best-corrected visual acuity （BCVA）.The differences were statistically significant between the two groups （P0.01）.The all hazes were within 2 grade.There weren＇t apparent cornea irritation and severe complications.CONCLUSION：LASEK was a safe,effective method for high myopia,but not effective for super-high myopia.
