Comprehensive evaluation of corneal optical characteristics using new generation optical coherence tomography

采用传统的角膜地形仪、波前传感器以及本研究新开发的OCT地形仪对正常眼、圆锥角膜、角膜移植术后和LASIK的角膜光学特性进行了全面的研究。结果表明，各类角膜高阶像差的变化趋势具有独特的规律。成功开发了基于OCT的角膜地形分析方法。OCT角膜地形仪的结果与常规方法相似。此外，在重度圆锥角膜中，其结果比常规方法更精确。

Corneal optical characteristics in normal eyes, keratoconus, post-keratoplasty, and LASIK were comprehensively investigated not only with conventional corneal topographers and wavefront sensor but also with OCT topographer that was newly developed in the study. The results indicated that the trends in corneal higher-order aberrations for each category showed unique pattern. The OCT based-corneal topographic analysis was successfully developed. The results of OCT corneal topographer were similar to that with conventional methods. In addition, its results were more precise than that with conventional methods in severe keratoconus.
