摘要
目的对40838例屈光性手术前,进行Orbscan-Ⅱ角膜地形图检查结果的筛选分析,为临床诊断角膜病及应用提供可靠依据。方法通过Orbscan-Ⅱ角膜地形图检测,针对角膜地形,全角膜厚度,角膜前、后表面高度及角膜屈率的数据进行分析,筛选出821例(1368眼),由8种特殊原因进行的结果分析。结果(1)进行选择性的治疗方式:后巩膜加固术,屈光性晶状体摘出联合人工晶状体置入术,有晶状体眼前房型人工晶状体植入矫治高度近视术。(2)避免一些手术禁忌症进行准分子激光屈光性手术:圆锥角膜、后圆椎角膜。(3)筛选450例1468项不正常的数据,不能进行任何治疗。结论Orbscan-Ⅱ角膜地形图检查对手术方式的选择、术前手术方案的设计、术后疗效的评价、避免一些手术禁忌症的病例进行手术是至关重要的检查工具。
Objective To investigate the results of ORBSCAN-Ⅱ corneal topography of 40838 patients before they were given refractive surgeries and to provide some references for clinical diagnosis of keratopathy. Methods Orbscan-Ⅱ corneal topography was examined and a pachymetry map, a keratometric map, an anterior and posterior evaluation map were shown. 82t of them were caused by eight special reasons. Results （1） take treatment with options： posterior sclera reinforcement, refractive removal of lens combined with insertion of artificial lens, phakic refractive lens implantation in high myopic patients; （2）avoid operations on patients with counter indiction, such as keratoconus, posterior keratoconus. （3） 1468 data of 450 patients were filtered abnormal and could not be given any treatment. Conclusions Orbscan-Ⅱ corneal topography is one of the routine examinations before refractive surgery. It is a useful device for designing and predicting effects before and after operation, and filtering contraindicated patients out.
