First Claim
Patent Images
1. A method for generating a radial alignment guide for an eye, comprising:
- collecting preoperative corneal topography data comprising a corneal vertex location and a pupil center location for an eye that is not dilated;
locating a dilated pupil center for the eye after the eye is dilated;
determining an adjusted offset between the corneal vertex and the dilated pupil center; and
displaying alignment data on an image of the eye based on the adjusted offset.

Abstract
A method for generating a radial alignment guide for an eye includes collecting preoperative corneal topography data. The data includes a corneal vertex location and a pupil center location for an eye that is not dilated. The method then includes locating a dilated pupil center for the eye after the eye is dilated. The method further includes determining an adjusted offset between the corneal vertex and the dilated pupil center and displaying alignment data on an image of the eye based on the adjusted offset.
