摘要:
A system (100) and method (300) for determining eye surface contour using multifocal keratometry is disclosed. The system includes a light source (102), a light detector (116), a processor (118), a non-transitory machine-readable medium communicatively coupled to the processor, and instructions stored on the non-transitory machine-readable medium. The instructions, when loaded and executed by the processor, cause the processor to project a light (302), using the light source, onto a plurality of surfaces (108, 112, 114) of an eye (106); create (304), using the light detector, an image of a plurality of reflections, each of the plurality of reflections created by reflecting the light off of one of the plurality of surfaces of the eye; determine (306) that the plurality of reflections are in focus in the image; and calculate (314), based on the determination, a curvature of the plurality of surfaces of the eye based on the image.
