1. A system for optimizing a clinical implementation of an ophthalmic lens, wherein the ophthalmic lens is indicated for treating at least one condition of a set of eyes, comprising:

  • an eye model associated with at least one processor, wherein the eye model is indicative of residual accommodation, and wherein the at least one condition comprises off-axis vision, post-LASIK patients, and combinations thereof;

    a simulator provided by the at least one processor that models the ophthalmic lens in the eye model having at least a first characteristic, wherein the simulator outputs a first outcome, the first outcome comprising simulated visual acuity at multiple levels of defocus of the ophthalmic lens in the eye model;

    at least one clinical input to the at least one processor comprising at least a second characteristic of a clinical eye associated with the clinical implementation, wherein the second characteristic at least substantially overlaps the first characteristic, and a second outcome, the second outcome comprising clinical visual acuity at multiple levels of defocus indicative of the clinical implementation of the ophthalmic lens; and

    a comparator instantiated by the at least one processor that compares the simulated visual acuity at multiple levels of defocus and the clinical visual acuity at multiple levels of defocus, and then compares differences between the simulated visual acuity at multiple levels of defocus and the clinical visual acuity at multiple levels of defocus to a predetermined tolerance threshold;

    wherein the at least one processor modifies the eye model to optimize at least the simulated visual acuity at multiple levels of defocus to bring the differences within the predetermined tolerance threshold.
