A supporting application for field experts on diagnosing Keratoconus disease and monitoring the healing stage after treatment by a unified system of image segmentation and image simulation processes of corneal images was developed. For execution of this study, actual 545 two-dimensional corneal images were used. Before 3-D imaging process, affected corneal areas were segmented by using Global Thresholding and Watershed image segmentation methods. The original images and the segmented images were displayed in three-dimensional forms and compared with each other by the help of the developed system. The study aims to retrieve depth information from the recorded images by Scheimpflug camera and Placido disc combination with normalized Diamond-Square method and monitoring the treatment process effectively. This study shows that displaying the disease and the healing process can be improved by using 3-D imaging methods. Also it's forseen that this study will be an important step for future studies on corneal imaging.
