目的：分析不适于行准分子激光原位角膜磨镶术患者的具体原因。方法：为3669例行准分子激光原位角膜磨镶术术前检查，分析514例未施行手术的原因。结果：514例中角膜厚度偏薄142例，占27．6％；角膜前屈和(或)后屈偏大110例，占21．4％；矫正视力未达正常106例，占20．6％；眼压偏高63例，占12．3％；眼底病变40例，占7．8％；急慢性结角膜炎症25例，占4．9％；摘掉隐形眼镜不足2周18例。占3．5％；年龄偏小、对手术安全性有顾虑等10例，占1．9％。结论：LASIK手术有明显的选择性和适应证。

Analysis of the reasons that 514 patients can not undergo laser in situ keratomileusis

Objective:To analyze the reasons that patients can not undergo laser in situ keratomileusis(LASIK).Method:The reasons that 514 examined patients did not undergo LASIK were analyzed.Results:Of 3 669 examined patients , 514(14.01%) were not performed LASIK. Of these 514 patients ,153(51. 2%) had some apprehensions of the surgery; 142(27.6%) had insufficient corneal thickness;110(21.4%) had too high corneal refractive power ; 106 (20.6%) had not ideal corrected visual acuity ;63(12.3%) had high intraocular pressure;40(7.8%) suffered from ocular fundus diseases;25(4.9%)had acute/chronic conjunctivitis or keratits; 18(3.5%) picked off contact lens less than 2 weeks;10(1.9%) had other reasons(some were too younger,others had apprehensions of the surgery).Conclusion: LASIK has obvious selection and strict adaptations.
