Abstract: An example method for cutting a plurality of lenticules from a donor cornea includes receiving a donor cornea, cutting a first layer of a first set of lenticules from the donor cornea. The method further includes, for each lenticule of the first set of lenticules, generating a record corresponding to the lenticule, the record including information about a part of the cornea from which the lenticule was cut.

Abstract: Systems and methods produce implants for treating keratoconus or other eye disorders. An example method includes identifying a subject with keratoconus. The method includes obtaining, with assessment means, an assessment of a cornea of a subject; determining, by processor(s), inverse measurements for correcting one or more irregularities associated with the keratoconus based on the assessment; and shaping, with a laser system, a donor cornea according to a pattern based on the inverse measurements. The example method may further include determining smoothing effects associated with the cornea, wherein the inverse measurements are based further on the smoothing effects, and the pattern for shaping the donor cornea is based further on the smoothing effects.
