Abstract
A Light Adjustable Lens (LAL) comprises a central region, centered on a central axis, having a position-dependent central optical power, and a peripheral annulus, centered on an annulus axis and surrounding the central region, having a position-dependent peripheral optical power; wherein the central optical power is at least 0.5 diopters different from an average of the peripheral optical power, and the central axis is laterally shifted relative to the annulus axis. A method of adjusting the LAL comprises implanting a LAL; applying a first illumination to the LAL with a first illumination pattern to induce a position-dependent peripheral optical power in at least a peripheral annulus, centered on an annulus axis; determining a central region and a corresponding central axis of the LAL; and applying a second illumination to the LAL with a second illumination pattern to induce a position-dependent central optical power in the central region of the LAL.
