目的应用pentacam系统及高斯光学公式评估Lasik术后患者的角膜屈力,从而探索更好更准确的Lasik术后人工晶状体度数的计算方法.方法 ①根据患者Lasik术前及术后的资料,应用临床病史法计算术后的角膜屈力;②在应用Pentacam系统测量Lasik术后角膜前后曲率半径的基础上,应用高斯光学公式计算其角膜的屈力;③测量值与目前的"金标准"临床病史法相比较.结果利用高斯光学公式计算所得的角膜屈力与临床病史法计算所得的角膜屈力相比差异无统计学意义.结论应用Pentacam测量角膜前后曲率半径并利用高斯光学公式计算角膜屈力的方法具有重要的临床意义及应用前景,尤其在Lasik术前资料丢失的前提下.

Objective To explore one better and more accurate method to estimate corneal power by a rotating Scheimpflug camera (Pentacam, Oculus) and Gaussian optics formula in eyes after myopic Lasik.Methods ①To calculate the effective power of the cornea as the sum of the refractive power of each surface by using Gaussian optics formula, taking into account anterior and posterior corneal radii and pachymetry (Pentacam,Oculus);②To calculate corneal power by Clincal history method;③To evaluate the result with the"gold standard "-clinical history method. Results There was no statistically significance between the clinical history method and the Gaussian optics formula. Conclusions The Gaussian optical formula is as accurate as the clinical history methods. Thus, it can significantly improve intraocular lens power calculation accuracy after Lasik surgery, especially when pre-reftactive surgery data are unavailable.
