Abstract
A device and method for marking corneal tissue. The device includes an ink reservoir portion and an ink resist portion. The ink reservoir portion is annular in shape and the ink resist portion occupies a central area within the annular shape. The ink reservoir portion and the ink resist portion are sized and structured to interface with the central cornea and to apply ink to the corneal tissue. The method includes applying ink to the cornea in an annular pattern.

A device for marking an anterior corneal surface, comprising:
- an ink reservoir portion and an ink resist portion;
- the ink reservoir portion being annular in shape and the ink resist portion occupying a central area within the annular shape;
- and
- the ink reservoir portion and the ink resist portion being sized and structured to interface with the anterior corneal surface and to apply ink to corneal tissue.
A method of creating a small aperture optical structure in a corneal epithelium of an eye, comprising:
- applying surgical ink to a portion of the corneal epithelium not deeper than a basement membrane of the corneal epithelium of a patient in an annular pattern surrounding a central uninked portion thereby creating an optical effect of the small aperture optical structure;
- wherein the annular pattern and the central uninked portion have a center point;
- and
- applying the surgical ink to a portion of the corneal epithelium that has been surgically removed from the cornea.
