Abstract
A method and device is provided for forming discernable markings within the cornea of an eye. Using a lens having a focal length to communicate and focus a laser to a focal point within the corneal layer of an eye, temporary markings can be formed within the corneal layer below its exterior surface. So formed the markings will remain for a number of days and provide the surgeon the ability to use the markings during eye surgery.
Claims18
A method for forming discernable markings within the cornea of an eye, comprising the steps of:
- positioning a lens having focal length to converge a laser communicating therethrough, to a focal point within the corneal layer of the eye, adjacent a surface of the cornea of said eye;
- and
- communicating a laser beam through said lens to thereby form a marking at said focal point of said lens, within the corneal layer of the eye.
An apparatus for forming discernable markings in an eye, comprising:
- a lens carrier, said lens carrier having at least one lens therein;
- said lens carrier adapted for positioning to a used position, adjacent the surface of a corneal layer of an eye;
- said lens having focal length configured to converge a light communicating therethrough, to a focal point within said corneal layer a distance below said surface of said corneal layer;
- and
- a YAG laser, said YAG laser positionable to communicate a laser beam through said lens to said focal point, whereby a marking is formed by said laser beam at said focal point.
