LASER MODIFICATION OF INTRAOCULAR LENS
First Claim
1. A system for modifying an intraocular device located within an eye, the intraocular device having a refractive property, the system comprising:
- a laser assembly configured to output a pulsed laser beam having a pulse width between about 300 picoseconds and about 10 femtoseconds; and
a controller coupled to the laser assembly, the controller configured to direct the laser assembly to output the pulsed laser beam into the intraocular device, the pulsed laser beam forming one or more slip zones within the intraocular device, the one or more slip zones configured to alter the refractive property of the intraocular device.

Abstract
A system of modifying an intraocular device located within an eye, wherein the system includes a laser assembly and a controller coupled to the laser assembly. The laser assembly outputs a pulsed laser beam having a pulse width between about 300 picoseconds and about 10 femtoseconds, and 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. 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.
