Abstract: An intraocular lens (IOL) includes an optic for focusing light and an accommodation assembly for axially moving and/or deforming the optic in response to naturally occurring actions of the eye, thus allowing a patient to more effectively focus on near objects. In addition, the optic may be multifocal or aspheric, wherein the maximum add power of the lens is combined with the increase in diopter power obtained through axial movement and/or deformation of the optic, resulting in enhanced accommodation.

Abstract: An intraocular lens (IOL) insertion apparatus for implanting IOLs through smaller incisions. The insertion apparatus includes an insertion cartridge that receives the IOL and cooperates with a handpiece. The cartridge includes a longitudinal lumen from a loading chamber to an open distal mouth that gradually narrows in dimension. A push rod having an extremely soft tip thereon urges the IOL through the cartridge and from the open distal mouth. The soft tip is made of low-stimulus material having a minimum ultimate elongation of 400%. Because of the extremely soft material of the tip, the outside diameter of the open distal mouth can be reduced to no more than 2.0 mm, enabling passage through incisions of 2.2 mm or less. The soft tip may be a thermoplastic elastomer having a relatively high elongation and relatively low modulus at elongations of 100-300%.

Abstract: Soft, flexible highly lubricious coatings for polymeric IOL insertion cartridges that allow IOLs to be easily inserted through small bore cartridges suitable for use with small (less than 3 mm) incisions are provided. These lubricious coatings allow IOLs to be inserted into the eye of a patient without the risk of lens damage or transfer of lubricants to the lens surface during implantation. Specifically, polymeric coatings comprising a matrix polymer having an equivalent weight greater than 5000 g/eq are used to form interpenetrating networks (IPN) on the surface of hydrophobic structural polymers. The IPNs thus formed entrap highly lubricious hydrophilic compounds within the IPN using multi-functional cross linkers.

Abstract: This invention provides an article of manufacture and method for controlling the application of a coupling agent, such as a silicone oil or mineral oil, on a surface of a tissue prior to contacting the tissue with an apparatus for non-invasive optical measurement of the concentration of an analyte. Such an apparatus is shown in WO 99/59464. The article ensures that a specific quantity of the coupling agent is deposited in a uniform layer over the entire target area of the tissue, thereby enhancing both the optical signal and the repeatability of thermal and optical coupling with the components of the apparatus. The coupling agent can comprise any of the coupling agents described in U.S. Pat. No. 6,241,663 that have desirable coupling properties for this application. In one embodiment, the article comprises (a) a backing and (b) a layer of coupling agent on at least one major surface of the backing. In this embodiment, the material of the backing must not absorb an excessive amount of the coupling agent.

The lubricity enhancing component includes a substituent component effective to reduce hydrolysis of said lubricity enhancing component relative to an identical lubricity enhancing component without the substituent component.

Abstract: A method for identifying artifacts occurring during a measurement of the concentration of an analyte in a biological sample by means of an apparatus that employs temperature-controlled optical probes, introduces electromagnetic radiation into tissue, and collects and detects radiation emitted at a distance from the point at which the electromagnetic radiation is introduced. The values of intensity of radiation emitted at different wavelengths, at different distances between the light introduction site(s) and the light collection site(s), and at different temperatures are collected and used in the method to generate a relationship between these values and the concentration of an analyte in the tissue or the disease state of a patient. The method involves the use of an algorithm that identifies artifacts in the data resulting from motion of the patient and allows the rejection of data sets that contain these artifacts.
