  • Vision correction with laser refractive index changes
    Patent number: 11833081
    Abstract: Methods and systems wherein laser induced refractive index changes by focused femtosecond laser pulses in optical polymeric materials or ocular tissues is performed to address various types of vision correction, and the laser induced changes to the refractive index avoid ablation and removal of the optical polymer materials while minimizing scattering losses.
    Type: Grant
    Filed: May 14, 2019
    Date of Patent: December 5, 2023
    Assignees: University of Rochester, Clerio Vision, Inc., Arizona Board of Regents on Behalf of the University of Arizona
