A system for modifying an intraocular device having a surface region and one or more subsurface regions, the surface region having a mechanical property, wherein the system comprises a laser assembly (14, 16, 20, 26, 28) configured to output a pulsed laser beam； and a processing unit (22) coupled to the laser assembly. The processing unit is configured to control the laser assembly to direct the pulsed laser beam at the one or more subsurface regions, the one or more subsurface regions being structurally altered in response to the pulsed laser beam while maintaining the mechanical property of the surface region.
