1. In a method for modifying the refractive power of a light adjustable lens in an optical system, with lens modifying radiation, the improvement comprising:
- measuring at least one aberration in the system containing the lens;
aligning a source of the modifying radiation so as to impinge the radiation onto the lens in a pattern that corresponds to the correction of the at least one aberration; and
controlling the quantity of the impinging radiation whereby to correct the at least one aberration;
wherein the impinging radiation is ultraviolet light obtained from a source thereof; and
the ultraviolet light has a wavelength in the range of 350 to 380 nm and is applied at a power of 2.5 to 3.5 mW.

Abstract
A method and instrument to irradiate a light adjustable lens, for example, inside a human eye, with an appropriate amount of radiation in an appropriate intensity pattern by first measuring aberrations in the optical system containing the lens; aligning a source of the modifying radiation so as to impinge the radiation onto the lens in a pattern that will null the aberrations. The quantity of the impinging radiation is controlled by controlling the intensity and duration of the irradiation. The pattern is controlled and monitored while the lens is irradiated.
