Method and apparatus for exposing a human eye to a controlled pattern of radiation spots

摘要

Primarily adapted for use in photo-thermal-keratoplasty procedures wherein a human eye is corrected for near-sightedness, farsightedness, astigmatism, and the like, by shrinking collagen within the cornea through controlled heating with infra-red radiation, an optical system is provided to controllably generate an infra-red radiation pattern. A moveable muti-faceted prism (87) is a primary optical element. Both the infra-red heating radiation and visible aiming radiation are delivered to the prism (87) by a multi-mode optical fiber (25). The optical elements are arranged to provide an attending physician with a clear view through the system of the eye being treated. Adjustment of the infra-red pattern is electrically controlled.
