Used in the clinical diagnosis of corneal astigmatism, quantitative analysis of corneal shape, display the corneal curvature by date of different colors, can display axial curvature map, tangential curvature map, height map, simulated corneal lens map and corneal 3D map. Can be used in the preoperative examination and postoperative effect evaluation of corneal refractive surgery can guide wearing contact data lens, to improve the accuracy of the adaptative contact lens.
