A method for generating a radial alignment guide for an eye includes collect-ing preoperative corneal topography data. The data includes a corneal vertex location and a pupil center location for an eye that is not dilat-ed. 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 align-ment data on an image of the eye based on the adjusted offset.
