目的:分析未行准分子激光原位角膜磨镶术(LA S IK)手术的原因。方法:对拟行LA S IK手术1 698例(3381眼)行详细的术前检查,对未行手术的174例(344眼)进行原因分析。结果:174例(344眼)未行LA S IK手术原因有:角膜厚度偏薄(<450μm),超高度近视,手术期望值过高,高眼压,视网膜裂孔及严重变性,圆锥角膜(包括隐匿性圆锥角膜)等。结论:LA S IK前必须进行严格的术前检查,以保证手术的安全。
OBJECTIVE: To analyze the reasons for the failure of excimer laser in situ keratomileusis (LA S IK) surgery. Methods: A total of 1 698 patients (3381 eyes) undergoing LA S IK operation underwent detailed preoperative examination and 174 patients (344 eyes) underwent surgery. Results: There were 174 cases (344 eyes) without LA S IK surgery because of thin corneal thickness (<450 μm), ultra-high myopia, high surgeries, ocular hypertension, retinal breaks and severe degeneration. Keratoconus) and so on. Conclusion: Before LA S IK, strict preoperative examination is necessary to ensure the safety of the operation.
