Randall V Tarr, Paul G Steffes: Non-invasive blood glucose measurement system and method using stimulated Raman spectroscopy. Georgia Tech Research Corporation, Deveau Colton & Marquis, September 14, 1993: US05243983 (289 worldwide citation)

Stimulated Raman spectroscopy is used to non-invasively measure the concentration of an Raman active molecule, preferably D-glucose in the ocular aqueous humor of living being. The apparatus and method make use of two monochromatic laser beams, a pump laser beam and a probe laser beam. The output po ...

David R Williams, William J Vaughn, Benjamin D Singer, Heidi Hofer, Geun Young Yoon, Pablo Artal, Juan Luis Arag dot over, Pedro Prieto, Fernando Vargas: Rapid, automatic measurement of the eye's wave aberration. University of Rochester, Blank Rome Comisky & McCauley, March 13, 2001: US06199986 (199 worldwide citation)

A wavefront aberration of an eye is determined, e.g., in real time. The eye is illuminated, and the light reflected from the retina is converted into spots with a device such as a Hartmann-Shack detector. The displacement of each spot from where it would be in the absence of aberration allows calcul ...

William J Neubert: Variable multiple color LED illumination system. Bausch & Lomb Surgical, Grant D Kang, Michael L Smith, February 6, 2001: US06183086 (189 worldwide citation)

An ophthalmic illumination system is provided that emits a light that is controllably variable in color. Because the light originates from LEDs, less heat is generated from the emitted light as compared to conventional ophthalmic illumination systems using tungsten or discharge sources.
