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.
