Inverse Optical Design Software
The 'inverse optical design' approach is the opposite of traditional optical design. Data consist of raw detector outputs from a Shack-Hartmann wavefront sensor, and parameters in the eye model are then determined via maximum-likelihood estimation methods. This invention is related to UA07-055 in that this disclosure reveals the software code...

Buttressed Haptic Design for Accommodating Intraocular Lens
This invention is a buttressed haptic that actuates the mechanically accommodating intraocular lens from the eye’s ciliary muscle. The technology allows the eye to change its focal distance using the eye’s natural mechanism of ciliary body muscle tension. The haptic receives radial tension from relaxation of the ciliary muscle to provide...
