目的:观察准分子激光上皮下角膜磨镶术(LASEK) 治疗白内障摘除联合人工晶状体植入术后屈光不正的安全性及疗效。方法:对白内障摘除联合人工晶状体植入术后屈光不正的42例49眼施行LASEK,术后随访6mo以上,记录角膜地形图、视力、屈光度数、角膜haze等情况。结果:术后6mo裸眼视力≥1.0者32眼(65.3%),≥0.8者42眼(85.7%)。球镜度数±1.0D内者为45眼(91.8%),±0.5D内者为34眼(69.4%)。柱镜度数±1.0D内者43眼(87.8%),±0.5D内者为31眼(63.3%)。术后6mo 0.5级haze 4眼(8.2%),其余均为0级,无继发性圆锥角膜、继发性青光眼、切削偏中心等并发症。结论:LASEK治疗白内障人工晶状体植入术后屈光不正屈光不正安全性高,疗效确切。

AIM:To evaluate the efficacy and safety of laser subepithelial keratomileusis (LASEK) treating ametropia after cataract extraction and intraocular lens implantation .METHODS:After cataract extraction and intraocular lens implantation, the ametropia in 42 cases (49 eyes) was treated with LASEK. Postoperative follow-up was 6 months, corneal topography, visual acuity, refractive diopter, corneal haze and any other conditions were recorded.RESULTS:The uncorrected visual acuity was over 1. 0 in 32 eyes (65.3%) ,and over 0. 8 in 42 eyes (85.7%) . 45 eyes (91.8%) were within ±1.0 sphere diopter, 34 eyes (69.4%) were within ±0.5 sphere diopter. 43 eyes (87.8%) were within ±1.0 cylinder diopter, within ±0.5D 31 eyes (63.3%) . Corneal haze was at 0.5 grade in 4 eyes and 0 grade in others at postoperative 6 months. There were no complications such as secondary keratoconus, secondary glaucoma, ablation decentration, etc.CONCLUSION:LASEK for ametropia after cataract extraction and intraocular lens implantation is an effective and safe surgery.
