Abstract
A template that is used with a probe to perform a medical procedure on a cornea. One embodiment of the template includes one or more openings that are used to align the probe with locations of the cornea that are to be denatured with energy transferred by the probe. By way of example, the openings may be located at 6, 7 and 8 millimeters about the center of the cornea. The denatured spots may collectively decrease the radius of curvature of the cornea. The template may have a bottom surface that conforms to the shape of the cornea. The template may have a centering feature that is used to center the template on the cornea and a vacuum channel that maintains the position of the template. The template openings may have stop features that limit a penetration depth of the probe.
