Abstract: The present application relates generally to a method for vision correction using corneal collagen crosslinking (“CCXL”), in which the physician is able to precisely control the pattern of ultraviolet (“UV”) energy delivered to the cornea, by means of a programmable masking array placed between the UV source and the cornea. A CCXL LCD masked is used to create various patterns of “on” and “off” pixels. The physician is able to control the degree of polarization of the LCD pixels, thereby allowing the physician to create various patterns of UV irradiation and thus, varying levels of CCXL.

Abstract: A device and method for applying light to the cornea of the eye as, for example, to promote crosslinking of collagen in the cornea for vision correction. The device may include a structure having form and size similar to a conventional contact lens. The structure may include an optically dispersive element such as a mass of an optically dispersive material that may be contained in a cavity of a reflective element. Light applied to the dispersive mass as, for example, by an optical fiber connected to the structure is dispersed in the structure and passes into the cornea. The patient may blink or close the eye during the procedure, which increases patient comfort and aids in maintaining hydration of the cornea.

Abstract: Apparatus and an accompanying method for calibrating a sensor signal conditioner coupled to a sensor. The signal conditioner sensor enables relatively easy and precise calibration of bridge sensors without the use of a microprocessor. When mated to a resistive bridge sensor, the sensor signal conditioner can digitally calibrate offset and gain, with an option to calibrate offset and gain coefficients and linearity over temperature. A second order compensation can be enabled for temperature coefficients of gain, offset or bridge linearity.
