Abstract: A multi-component accommodating intraocular lens (AIOL), comprising a recessed anterior optical element, a posterior component, and at least two longitudinal haptics each coupled to at least a portion of the anterior optic and at least a portion of the posterior component. Each haptic has an anterior most-portion that is disposed more anteriorly than a corresponding portion of an edge of the anterior optical element.

Abstract: A multi-optic accommodating intraocular lens (A-IOL) for implantation in a capsular bag of an eye having an optical axis, includes a posterior component, an anterior component that is translatable relative to the posterior component along an optical axis of the A-IOL, and a biasing element that joins at least a portion of the anterior component and at least a portion of the posterior component. The A-IOL is quantitatively characterized by an axial compression characteristic such as a spring constant or an axial restoring force. The axial compression characteristic is capable of keeping the components sufficiently vaulted apart for enabling near vision yet weak enough to allow the eye's accommodative mechanism to pull the optics close together for distance vision.

Abstract: A process for preparing a polymer of an ethylenically unsaturated monomer, in which the monomer is obtainable from a biocatalysed reaction or a fermentation process, and wherein the monomer contains cellular material and/or components of a fermentation broth, forming the polymer by polymerising the ethylenically unsaturated monomer or a monomer mixture comprising the ethylenically unsaturated monomer, wherein there is substantially no removal of the cellular material and/or components of the fermentation broth from the ethylenically unsaturated monomer.

Abstract: A multi-component accommodating intraocular lens (A-IOL) for implantation in a capsular bag of an eye having an optical axis, includes an anterior optical element and a posterior component that are connected by at least one compressible haptic. The compressible haptic, by definition, has a deformation feature that is resiliently deformable. The deformation feature allows the nominal overall diameter of the A-IOL to dynamically vary over a selected range in response to a capsular bag dimension that is different than that of an average population value, or in response to a change in the size and/or shape of the capsular bag due to post-operative capsular bag shrinkage, without substantially changing the separation distance between the anterior and posterior components of the A-IOL absent an intended accommodating force. Methods are also disclosed.

Abstract: A thin intraocular lens for inhibiting posterior capsular opacification (PCO) includes an optic having a sharp edge which extends posteriorly and between a posterior concave region and an outer-most peripheral edge surface that extends parallel to the optical axis.

Abstract: The present invention provides a holder/package for supporting a two optic accommodating intraocular lens device. The holder/package is capable of holding the device, for example while taking measurements or performing manufacturing process steps on the device and/or for packaging and shipping of the device. In a preferred embodiment, the holder/package supports the device along first and second haptics thereof with the optics substantially untouched by the holder/package.

Abstract: A method, lens and assembly are disclosed for making a dual optic AIOL from a lens blank having first and second optics and at least one haptic extending therebetween larger in area than the haptic(s) of the finished AIOL. Material is removed from the semi-finished haptic to form the finished haptic of any desired configuration.

Abstract: A hammer union comprises a thread end, a nut end and a hammer nut which, when cinched up, compresses a composite seal assembly thereby preventing leakage. The seal assembly comprises a metal insert of a size to pass into the seal groove of conventional hammer unions and a small seal acting between the insert, the thread end and the nut end. The small seal is conveniently an O-ring and is of a size that is compressed when the seal assembly is inserted into the thread end of the hammer union, thereby preventing the seal assembly from falling out of the threaded end when it is inverted. The metal insert provides another groove opposite the small seal to receive a second O-ring which acts as a spring to bias the small seal into sealing engagement, thereby allowing the new seal assembly to accommodate more variation in the length of the existing seal groove in prior art hammer unions.

Abstract: Apparatus, products, and methods are described that relate to blending various disparate optical surfaces in a smooth and continuous manner. In cross section, the two disparate surfaces are represented as meridional profiles. A blend zone profile is described by a single third-order polynomial. In the case of rotationally symmetric optics, one cross-section suffices for the description of the entire surface. In the case of non-rotationally symmetric optics, an increased number of cross-sections are necessary to produce the desired three-dimensional surface, thus meridional profiles are calculated at selected azimuthal locations to describe the full surface.

Abstract: A rongeur has a detachable crossbar to enhance cleaning and sterilization. A pin in a slot on one of the rongeur's handles is moveable out of the slot to permit extended retraction of the crossbar to a position in which it may disengage from the shank of the rongeur.

Abstract: An automatic chemical analyzer utilizes reagents supplied in reagent bottles. The reagent bottles are labeled on their bottom surfaces with an identification label bearing a machine-readable identification code. The automatic chemical analyzer includes a reagent tray having a plurality of tray apertures therein which receive coded reagent bottles and which expose the bottom surface of each bottle for optical viewing of the machine-readable identification code. The analyzer further includes optical scanner means positioned below the reagent tray for reading the machine-readable identification code on the bottom surfaces of reagent bottles within the tray apertures. The tray apertures are selectively located over the optical scanner means so that the analyzer can identify the reagent bottle and the contents thereof.The identification label has a spaced pair of position reference dots defining and orienting a label area.

Abstract: A dispenser apparatus for trays, plates or the like. The dispenser apparatus includes a top member having an opening therethrough for the trays, plates or the like and includes a base.

Abstract: A flange spreading implement includes a set of pins freely slide into the bolt holes of the flanges to be spread apart. The pins are of a size selected to bind in the flange bolt holes upon the application of a moment to the pins. Arms are connected to the pins and extend beyond the periphery of the flanges to be spread. A force applier, such as a hydraulic motor or screw, is used to apply a force to the arms in a direction generally parallel to the axis of the flanges. This imparts a moment to the pins, causing them to bind in the bolt holes and thereby grip the flanges. The force applier applies sufficient force to spread the flanges apart to allow a valve, meter, flow treater, gasket, orifice plate or the like, to be removed from between the flanges.
