近视未行LASIK手术824例分析

Analysis of 824 myopia cases not suitable for LASIK

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.
