| Research Abstract |
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.
