Abstract: PEO-containing quaternary ammonium compounds have good broad spectrum antimicrobial activity. These compounds are useful in pharmaceutical compositions as preservatives and in contact lens care compositions as preservatives and/or disinfectants.
Abstract: Compositions and methods are provided for cleaning and wetting of contact lenses, especially rigid, gas-permeable contact lenses. The compositions comprise low molecular weight polyalkylene oxide modified siloxanes, which are particularly effective in removing lipids from the surface of contact lenses.

Abstract: A corneal topographer including a directional light source, a CCD and a positioning stage all controlled by a computer for automatically centering and focusing the corneal image onto the CCD. The computer receives video signals from the CCD representing the corneal image, which is digitized and displayed on a real-time basis on a monitor screen. A reflection of the directional light source is positioned to align in the center of the corneal image. An operator moves an optics head to place the corneal image on the monitor screen, roughly focuses the image, and then commands the computer to take over. The computer calculates the distance between the image of the directional light source and the center of the CCD, and activates the positioning stage to move the directional light source image to the center. The positioning stage is moved within a focusing range, where several positions and corresponding intensity characteristics of the directional light source image are tabulated.
Abstract: Methods for preventing and treating corneal haze resulting from exposure of the eye to laser irradiation are disclosed. The methods include administration of compositions of wound healing modulators to the eye. Compositions for use in preventing and treating the corneal haze are also disclosed.

Abstract: A method for attaching haptics to an optic of an intraocular lens including the steps of providing the peripheral edge of the optic with at least one hole, inserting an end of the haptic into the hole, aiming a laser which emits radiation within the visible spectrum which is matched to the absorption spectrum of the haptic at a portion of the haptic within the hole and firing the laser so that the radiation passes through the optic essentially without absorption and is absorbed by the haptic, thereby causing the haptic to swell an amount sufficient to mechanically anchor the end of the haptic within the optic.
Abstract: Disclosed are novel compositions comprising mixtures useful to treat the metabolically impaired and to improve patient compliance. Included are non-racemic mixtures of certain chiral spirofluorenehydantoins. Methods of use to treat glucose toxicity and complications arising from diabetes mellitus are also disclosed.
Abstract: Certain anionic surfactants are used to enhance antimicrobial effectiveness in comfortable, sustained release ophthalmic compositions containing polyelectrolytes, such as carboxyvinyl polymers, polystyrene sulfonic acid polymers and cationic exchange resins, as well as at least one active ingredient.
Abstract: Ophthalmic pharmaceutical vehicles which become viscous on contacting the eye are disclosed. Ophthalmic compositions of the vehicle and a pharmaceutically active drug are also disclosed.
Abstract: A method for focusing a corneal topographer by determining the maximum intensity of a reflected light during a first focusing sweep and capturing the topographic image during a second sweep when the reflection intensity reaches the maximum intensity.

Abstract: Polyethylene oxide (PEO) coatings providing improved biocompatibility for implantable medical devices are disclosed. The PEO coatings comprise functionalized end-capped PEO which is attached at one end to the medical device. The PEO compounds are then exposed to a high energy source for a time sufficient to cause the PEO compounds to form a cross-linked, insoluble network. These PEO coatings are able to survive ethylene oxide sterilization procedures with minimal loss of protein or cell repulsion ability.
