Abstract:
1. A method for determining an optimal position of an eye relative to an ophthalmic device comprising the steps of: (a) receiving data comprising an image of a surface of an eye with the eye at a first position relative to an ophthalmic device; (b) locating an edge feature in the image, the edge feature being selected from a group consisting of a scleral blood vessel and an iris feature; (c) performing a sharpness calculation on the edge feature using a predetermined algorithm to yield a sharpness value; and (d) adjusting the eye surface to a second position relative to the ophthalmic device based on the sharpness calculation on the edge feature; and (e) repeating steps (a)-(d) until the sharpness value is maximized, wherein in each subsequent cycle the first position of step (a) is the second position of step (d) from the previous cycle and the second position of step (d) is a new position, indicating that an optimal eye position has been achieved.
