Abstract
Proper selection and centering of an intraocular lens (IOL) is provided. An image of an eye, which may be captured during pre-operative tests and provided to a program operable to calculate the power and axis orientation of the IOL, is used to determine the location and orientation of the IOL. This produces an output or placement guide used to properly center and orient an IOL within the eye.
