A template of flexible material that is so fenestrated or otherwise configured as to be self-adherent to the cornea and to readily conform to the curvature of the cornea, the template being further configured to provide ready centering on the visual axis and to establish a removable pattern of knife-guiding slits, wherein the pattern is selected as a particular one, from a plurality of available patterns, each of which has been designed to serve a different but predetermined optical change via an RK and/or an AK procedure. The self-adherence is relative, intended only to serve correctly guided use of a knife, in that the template is readily removable after the intended cuts have been made. A variety of embodiments is disclosed. |
