摘　　要：目的:评价准分子激光双面式切削原位角膜磨镶术(both-sidedLASIK,BSL)的安全性和有效性。方法:2004-12/2005-10我院进行BSL手术治疗的高度近视患者38例75眼,回顾性的对临床疗效进行分析。结果:随访9～15mo,38例患者均未出现严重并发症。术前、术后1d和9mo的平均裸眼视力分别为0.07±0.05、0.67±0.29、0.92±0.23,两两之间比较差异均有统计学意义(P<0.01)。1mo时见7眼(9%)有1级Haze形成,较常规LASIK稍多。电脑验光1d和1mo与3mo和6mo之间比较差异均有统计学意义,1mo和3mo与6mo和9mo之间比较差异均无统计学意义。结论:BSL术后能够获得较好的裸眼视力,无严重的并发症出现,屈光回退程度较轻,Haze形成较常规LASIK稍多,对角膜较薄的高度近视患者是一种较为理想、安全、有效的治疗方法。AIM： To assess the safety and effectiveness of both-sided LASIK （BSL）. METHODS： Seventy-five eyes with high myopia were treated with BSL, and the dinical results were analyzed. RESULTS： All of 38 cases were successful without severe complication and followed up 9 months to 15 months. Preoperatively, the average uncorrected visual acuity（UCVA） was （0.07± 0.05）,1 day and 9 months after operation, the average UCVA was （0.67 ± 0.29）, （0.92 ± 0.23）, respectively. There were obvious difference （P 〈0.01） among preoperative UCVA, postoperative UCVA at 1 day and 9 month, respectively. Seven eyes （9%） showed denser haze（grade 1 ） at 1 month. More corneal haze was observed in BSL than in routine LASIK. There were obvious difference among compute refraction at I day and 1 month as well as at 3 months and 6 months. CONCLUSION： BSL is a safe and effective refractive surgery for treating high myopia with thinner cornea, and it can obtain better UCVA without postoperatively severe complications and significant regression.
