Abstract: An array of four infrared LEDs and an array of four phototransistor receivers with each LED and phototransistor mounted inside a light baffle. The LEDs are positioned in a substantially vertical array just outside one side wall of the cassette. The vertical line on which the LEDs are arranged is substantially parallel to the direction in which the fluid/air interface moves within the cassette. The LEDs are aimed upwardly at an angle of approximately 20.degree. from horizontal. A corresponding substantially vertical array of four phototransistor receivers is mounted outside the cassette opposite the LEDs such that each of the receivers is aimed at its corresponding LED.
Abstract: Compositions containing a stable, liquid, ophthalmically acceptable enzyme and methods involving the combined use of these compositions with a polymeric antimicrobial agent are disclosed for the simultaneous cleaning and disinfecting of contact lens. Methods for a daily use regimen are also disclosed.

Abstract: An aspiration tip having a relatively rigid cannula attached to a hub and an open end opposite the hub. The open end is sealed with a cap made from a soft, flexible material, such as rubber or soft plastic. The soft material reduces the likelihood that the posterior capsule will tear during cortical clean-up and capsule polishing.

Abstract: A single piece soft foldable IOL having open loop haptics of specific thickness and geometry. The unique geometry provides an IOL with improved fixation and centration.
Abstract: The intraocular use of combinations of stromal cell growth stimulators (e.g., TGF-.beta.) and antimetabolites (e.g., mitomycin C) in connection with glaucoma filtration surgery is described. The combination is applied to the surgical site to attract, mitogenically activate, and neutralize the potential for extracellular matrix synthesis leading to scar formation by stromal cells. Without such treatment, the formation of scar tissue may lead to impairment of the outflow of aqueous humor at the surgical site, particularly the fistula. The mitogenic activation of the stromal cells makes these cells susceptible to the anti-metabolites. This enables the antimetabolites to suppress the proliferation of the fibroblasts and other associated stromal cells to a much greater extent, relative to the proliferation seen when the metabolites alone are utilized.
Abstract: The use of certain dopaminergic compounds for controlling elevations of intraocular pressure is disclosed. The compounds are ergoline derivatives. The most preferred compound is cabergoline. The compounds have been found to produce a significant reduction of intraocular pressure.

Abstract: A single piece intraocular lens folder that has a generally planar, open frame in the shape of a rounded "A" with a rimmed, open head at the top of the "A". The base of the "A" forms a pairs of opposing legs or handles that join to form a hinge at the intersection where the handles attach to the head. The hinge allows the handle to be squeezed together and spring apart when released. Squeezing the handles together causes the sides of the head to spread apart, thereby stretching the top edge of the head rim and pulling the top edge downward toward the hinge. The open head contains a pair of support jaws and a pair of serpentine folding jaws. The location of the serpentine jaws is such that when the top edge of the head rim moves toward the hinge, the serpentine jaws are squeezed together, causing the IOL to be folded in half. The serpentine shape of the folding jaws allow the haptics to pivot downward, thereby permitting the IOL to be folded along a plurality of axes.

Abstract: A diffractive, multifocal ophthalmic lens including an apodization zone with echelettes having a smoothly reduced step height to shift the energy balance from the near image to the distant image and thus reduce the glare perceived when viewing a discrete, distant light source.
Abstract: Angiostatic steroids for use in controlling ocular hypertension are disclosed. Pharmaceutical compositions of the angiostatic steroids and methods for their use in treating ocular hypertension, including controlling the ocular hypertension associated with primary open angle glaucoma, are disclosed. In addition, the combination of the compounds with glucocorticoids for the prevention of elevated IOP during the treatment of inflammation is disclosed.
Abstract: The intraocular use of combinations of lens epithelial cell growth stimulators (e.g., TGF-.beta.) and antimetabolites (e.g., mitomycin C) is described. The combination is applied to the capsular bag to prevent or retard the formation of secondary cataracts following cataract surgery. The lens epithelial cell stimulators activate DNA synthesis in dormant lens epithelial cells, and thereby make those cells susceptible to the anti-metabolites. This enables the antimetabolites to suppress the proliferation of lens epithelial cells to a much greater extent, relative to the proliferation observed when the metabolites alone are utilized. The increased suppression of the growth of lens epithelial cells results in a significant improvement in the ability to prevent or retard the formation of opacities on the lens capsule (i.e., secondary cataracts).

Abstract: Improved soft, foldable acrylic lens materials which are particularly suited for use as IOLs, but which are also useful as other ophthalmic devices, such as contact lenses, keratoprostheses, and corneal rings or inlays, are disclosed. These materials contain only two principal components: one aryl acrylic hydrophobic monomer and one hydrophilic monomer. The materials of the present invention are copolymers comprising at least about 90% by weight of the two principal monomeric components; provided that the amount of the hydrophilic component is not greater than that of the aryl acrylic hydrophobic component. The remainder of the material comprises up to 10% by weight of one or more additional components, such as cross-linking, UV-light absorbing, and blue-light absorbing components.The aryl acrylic hydrophobic monomers suitable for use in the materials of the present invention have the formula ##STR1## wherein: X is H or CH.sub.3 ;m is 0-6;Y is nothing, O, S, or NR, wherein R is H, CH.sub.3, C.sub.n H.sub.
