Claim Text:
1. A method for locating a boundary of at least one anatomical structure of an eye of a patient comprising: providing image information pertinent to at least one anatomical structure of the eye; processing the image information to identify a first set of candidate edge locations for the at least one anatomical structure of the eye, the first set of candidate edge locations being disposed in a first boundary surface portion of the at least one anatomical structure, using a least-squares technique to fit a first mathematical surface model to the first set of the candidate edge locations, processing the image information based on proximity to the first mathematical surface model to identify a second set of candidate edge locations for the at least one anatomical structure, the second set of candidate locations being disposed in a second boundary surface portion of the at least one anatomical structure that is different from the first boundary surface portion, and using a least-squares technique to fit a second mathematical surface model to the combined first and second sets of candidate edge locations; and locating a boundary of the at least one anatomical feature based on the fit of the least-squares technique.
