A system for generating three dimensional shapes for a cornea and a lens of the eye is disclosed, the system comprising an illumination source configured to illuminate the eye with multiple sections of light, a camera configured to obtain multiple sectional images of the eye based on an illumination from the multiple sections of light, and a computer image processor in communication with the camera, wherein the computer image processor is configured to perform the following processes on an obtained sectional image:
(i) identifying arcs, in two-dimensional space, corresponding to anterior and posterior corneal and lens surfaces of the eye by image analysis and curve fitting of the obtained sectional image, (ii) determining an intersection of lines ray traced back from the identified arcs in two-dimensional space with a known position of a section of space containing the section of light that generated the obtained sectional image, wherein the determined intersection defines a three-dimensional arc curve, and (iii) reconstructing three-dimensional shapes of the anterior and posterior cornea surfaces and the anterior and posterior lens surfaces based on fitting the three-dimensional arc curve to a three-dimensional shape.
