Claim:
1. A system for optical treatment of an eye having a cornea, the system comprising: a delivery device; and dopant operably coupled with the delivery device so as to be deliverable from the delivery device to the eye in a dopant pattern, the dopant being a substance that, when delivered to the eye, locally changes refractive index values of the cornea without reshaping the cornea; wherein the delivery device is configurable to deliver the dopant to the eye in the dopant pattern so that the delivered dopant locally changes refractive index values of the eye so as to impose a desired correction to change a refractive index of the cornea of the eye to mitigate an optical aberration of the eye, and wherein the delivery device includes a contact lens configured for placement on a portion of the eye, the contact lens having dopant carrier which releasably carries the dopant, the dopant being configured to be released from the portion of the contact lens when the portion of the contact lens is irradiated.
