Abstract

See full text

A laser system that includes a laser source emitting a laser beam along an axis and a keratometer. The keratometer includes a first set of individual light sources that are equally spaced from one another along a first ring and that direct a first light toward an eye and a second set of individual light sources that are equally spaced from another along a second ring and direct a second light toward the eye, wherein the first ring and said second ring are co-planar and concentric with one another about the axis. The laser system includes a telecentric lens that receives the first light and second light reflected off of the eye and a detector that receives light from the telecentric lens and forms an image. The laser system also includes a processor that receives signals from said detector representative of the image and determines an astigmatism axis of the eye based on the signals.
