摘要: A sensor probe suited for implanting into the skin of a person includes a sensor body which may be formed from a polymer which includes 2-hydroxyethyl methacrylate (HEMA). A sensing system is supported by the body. The sensing system exhibits a detectable change when the probe is exposed to the analyte in the fluid. The sensing system may include an enzyme capable of catalyzing a reaction of the analyte to form a reaction product and a dye system which absorbs in the infrared region of the spectrum in response to the reaction product.

摘要: A burette (10, 110, 200) suitable for delivery of a reagent into a target solution (50) employs diffusion for delivering the reagent. The reagent is in the form of a solution, which is combined with a matrix material (22), such as a gel or porous ceramic. A membrane (32) covers a delivery outlet (20) to the burette. In one embodiment, the delivery outlet comprises a plurality of fine bores (36), each one filled with or covered by a membrane (38). Stirring of the burette or target solution is achieved with a stirring means (104, 106). A heating or cooling means (80) heats a tip (16) of the burette.

摘要: A phakic intraocular lens includes a body having a flat anterior-facing surface and a curved posterior-facing surface that defines the optical power of the lens. The lens allows fluid to flow between the phakic lens and the iris and between the phakic lens and the natural lens. An enlarged outer rim helps maintain the position of the lens. Some embodiments are provided with openings, channels, or both at the circumferential edge of the flat anterior-facing surface or the lens body to help prevent the flat surface of the lens from sealing against the iris.

摘要: This invention is a method for sculpturing a laser beam (13) in a predetermined pattern using a device (17) between the laser source (11) and the target (23). The method comprises a series of sequential steps in which at least two regions of the cornea (177) are each exposed to increasingly larger portions of the laser beam (13). In the preferred embodiment, two pairs of complementary regions of the cornea (177) will be sequentially exposed to laser radiation. In each such region, a first part will be exposed to a substantially segmental portion of the beam (13), and then at least another larger substantially segmental portion of the beam (13) in which the larger segmental portion, includes the smaller segmental portion. In the preferred embodiment, the target (23) is the human eye, and the predetermined pattern is intended to shape the eye to treat it for astigmatism, myopia, or hyperopia.
