Claim:
1. A method of changing the index of refraction of an optical hydrogel that is a component of an optical device for vision correction, the method comprising: providing a physician with a laser system to irradiate select regions of the optical hydrogel following implantation of the optical device into the eye of the patient, the laser system comprising a laser having a laser pulse energy from 0.01 nJ to 50 nJ and a light wavelength from 600 nm to 900 nm; wherein the irradiated regions are formed by scanning the laser light in an X-Y plane, the irradiated regions characterized by a positive change in refractive index of from 0.01 to 0.06.
