摘要:
A laser system for modifying the index of refraction of an optical hydrogel material. The laser system comprises a computer program to determine the position and shape of refractive structures to be written into the optical hydrogel material to correct a patient's vision, and a focused laser that generates laser light having a wavelength of from 400 nm to 900 nm, and which operates with an average power of 10 mW to 1000 mW to produce a pulse energy from 0.05 nJ to 1000 nJ with a peak intensity at focus of greater than 1013 W/cm2. The refractive structures exhibit a change in the index of refraction of 0.01 to 0.06 in the optical hydrogel material.
