目的:探讨近视行术前检查而未行准分子激光原位角膜磨镶术(laser in situkeratomileusis,LASIK)原因。方法:对2891例近视患者常规进行术前检查,未行手术824例进行原因分析。结果:未行LASIK手术824例中,角膜厚度不足297例(36.0%);存在思想顾虑194例(23.5%);瞳孔过大96例(11.6%);角膜前后表面高度(眼前节全景仪Pentacam基于Scheimpflug成像原理,获得全角膜前、后表面角膜地形图及各点角膜厚度,可应用于圆锥角膜筛查和早期诊断)偏高50例(6.1%),高曲率46例(5.6%),矫正视力不佳43例(5.2%),眼底病变31例(3.8%),干眼31例(3.8%),其它36例(4.4%)。结论:LASIK手术是一种选择性手术,必须进行严格的术前筛查,全面科学评估检查结果,医患之间加强沟通,严格掌握手术的适应证和禁忌证。

AIM:To identify the reasons for myopia patients not suitable for laser in situ keratomileusis(LASIK)after preoperative assessment.METHODS:Two thousand eight hundred ninety-one myopia patients were examined.824 cases of them did not undergo LASIK,the reasons were analyzedRESULTS:A total of 297 patients(36.0%)were insufficient of the corneal thickness ;194 patients(23.5%)had some apprehension about the surgery ;96 patients(11.6%)had a larger pupil ;50 patients(6.1%)had a larger height of the corneal anterior and posterior surface;the corneal curvature of 46 patients(5.6%)was higher;43 patients(5.2%)had no ideal best-corrected visual acuity;31 patients(3.8%)had the fundus disease,31 patients(3.8%)had dry eye and 36 patients(4.4%)had the other reasons.CONCLUSION:LASIK is an alternative surgery.We must perform preoperative assessment carefully,evaluate the test results comprehensively and scientifically,enhance communication between doctors and patients and strictly master surgical indications and contraindications.
