ADJUSTABLE OPTICAL ELEMENT WITH MULTIZONE POLYMERIZATION

摘要

The present invention relates to an optical element for correcting refractive error in an eye. The optical element includes a first portion having a first volume that remains substantially constant when exposed to an energy, and a second portion having a second volume that is adapted to change when exposed to the energy. This optical element results in a device that can correct severe ametropic conditions, without ablating any portion of the element itself or the cornea.
