OcuSciences Inc.'s OcuMet Beacon is a noninvasive and rapid diagnostic screening tool for retinal disease. The current ophthalmic standard of care, optical coherence tomography, evaluates structural change in retinal thickness or swelling after retinal damage has occurred, but OcuMet can provide a level of functional testing before damage occurs, which is especially important for latent diabetics or patients undiagnosed for retinal diseases.

A new intraocular lens being developed by LensGen Inc. essentially mimics the younger, natural human lens in curvature and flexibility so that cataract patients are able to physically accommodate over an entire range of vision from distance to near.
