초록 ▼

The invention contemplates controlled ablation of the cornea, using ultraviolet laser radiation, wherein irradiated flux density and exposure time are so controlled as to achieve desired depth of the ablation. Sculpturing action results from precharacterized distribution of flux density across the cross-section of laser-beam projection, in the context of beam size, at cornea incidence, to match the area to be ablated, and the duration of exposure determines the extent of curvature change. Illustrative techniques and situations are disclosed, for myopia correction, for hyperopia correction, and for astigmatism correction.

대표청구항 ▼

Apparatus for operation upon the external surface of the cornea of an eye of a patient, comprising laser means producing on a central axis a circular output beam having a predetermined flux-density distribution in the ultraviolet portion of the electromagnetic spectrum, optical means including precharacterized beam-splitter means positioned in said beam for dividing laser radiation into a reflected-component beam and into a transmitted-component beam, the precharacterization of said beam-splitter means being such that in the reflected-component beam flux-density distribution is a circumferentially uniform decreasing function of radius about the central axis of said reflected-component beam without materially changing spatial and temporal coherence of said reflected-component beam, whereby when the axis of said reflected-component beam is aligned with the optical center of an eye, a myopia-correcting curvature change may be effected in the anterior surface of the cornea.
