Abstract
A light adjustable lens illumination system comprises an illumination source, for generating a light beam; a light delivery system, for projecting the light beam onto a Light Adjustable Lens (LAL), implanted into an eye, wherein a fraction of the light beam propagates past the LAL to a retina of the eye; and a protective beam-shaper, for shaping the light beam to have an intensity pattern with a relative central intensity reduction that varies along an axis; wherein the relative central intensity reduction at the retina is greater than the relative central intensity reduction at a LAL plane.
