目的:探讨术前检查中发现屈光不正患者伴有偏高角膜曲率时的归属和对策。方法:利用角膜地形图对拟接受准分子激光手术的46例屈光不正患者进行角膜曲率的检查和分析。结果:因出现圆锥角膜或角膜薄、度数高而不能手术者10例(18眼),初查曲率偏高、随查3mo后行LASIK矫正术3例(6眼),初查曲率偏高、需进一步随查而暂未手术33例(63眼)。结论:单纯角膜曲率偏高不能作为准分子激光手术的禁忌症,但也不能盲目手术。角膜曲率的检查对选择治疗方式具有一定的意义。
Objective: To investigate the ownership and countermeasures of patients with high refractive corneal curvature found in preoperative examination. Methods: Corneal topography was used to examine and analyze corneal curvature in 46 patients with ametropia who were undergoing excimer laser surgery. Results: The initial examination of curvature was high due to the keratoconus or cornea thin, high degree of incapacity and surgery in 10 cases (18 eyes). The curvature of the initial examination was high with 3 cases of LASIK orthodontic surgery in 3 cases (6 eyes) Thirty-three cases (63 eyes) needed further investigation without surgery. Conclusion: High corneal curvature alone can not be used as a contraindication for excimer laser surgery, but it can not blind surgery. Corneal curvature of the treatment of choice has some significance.
