METHODS OF LASER MODIFICATION OF INTRAOCULAR LENS
A method of modifying a refractive profile of an eye having an intraocular device implanted therein, wherein the method includes determining a corrected refractive profile for the eye based on an initial refractive profile, identifying one or more locations within the intraocular device based on the corrected refractive profile, and directing a pulsed laser beam at the locations to produce the corrected refractive profile. A system of modifying an intraocular device located within an eye, wherein the system includes a laser assembly and a controller coupled thereto. The laser assembly outputs a pulsed laser beam having a pulse width between 300 picoseconds and 10 femtoseconds. The controller directs the laser assembly to output the pulsed laser beam into the intraocular device. One or more slip zones are formed within the intraocular device in response thereto, and the slip zones are configured to modify a refractive profile of the intraocular device.
