Abstract: A flexible and transparent corneal endothelium protective device includes a relatively thin protective barrier portion, and a relatively thicker form-providing rim around the barrier portion. An access opening is provided through at least one of the rim and the barrier portion. The protective device is foldable for insertion through a surgical incision, is resilient such that it springs into shape once positioned in the eye, and is sufficiently flexible such that it may easily be removed through the incision in the eye near the completion of the surgical procedure. Various shapes are provided for the device. The protective device is inserted through the small incision and maneuvered into the space between the iris and the cornea and permitted to unfold. During surgery, instruments and other devices may be passed through the surgical incision and extend through an access opening of the protective device to operate on the lens.

Abstract: A collagen forceps includes two elongate members coupled at a proximal live hinge. Each elongate member is provided with a knurled finger pad ergonomically contoured to stably receive a finger or thumb of a physician, and a manipulation tip having an interior collagen rod gripping surface. The gripping surfaces each include an angulated or curved surface provided with ridges and shaped to engage the collagen rod axially with the elongate members. Preferably each manipulation tip is also provided with a silicon boot. In addition, the instrument is also provided with a projection having a dilation/insertion tip. The collagen forceps of the invention enables a more controlled implantation of collagen rods through the punctal opening and into the naso-lacrimal duct. The contoured finger pads provide a physician with a more comfortable and more controllable instrument.

Abstract: A microsurgical scalpel assembly including an elongate scalpel handle and a scalpel blade affixed at one end of the scalpel handle and a shield releasably affixed to the one end of the scalpel handle and extending away from the handle to operably surround the scalpel blade to isolate sharp surfaces of the scalpel blade from a surgeon and to protect the blade from damage during a re-sterilization autoclave procedure.

Abstract: A punctum dilating and plug inserting instrument includes a cylindrical body with a first end being a plug inserting tip, and a second end being a punctum dilating tip. An elongated button is arranged longitudinally along the body. The button includes a fixed end and a slidable end; the fixed end being positioned between the slidable end and the plug inserting tip. The button also includes an outwardly bowing inner surface spaced from the body. A wire is slidably positioned longitudinally within the body. The wire includes an outer end protruding from the plug inserting tip, and an inner end attached to the slidable end of the button. A conventional punctum plug is attached to the outer end of the wire, and can be inserted into a punctum after the punctum is dilated by the dilating tip.

Abstract: A surgical instrument cleaner includes a containment chamber with an intake opening on a front thereof and an exhaust vent on a rear thereof. A manifold is positioned in the intake opening, and connected to a steam source. Nozzles arranged around the manifold emit converging steam jets at a single point positioned away from a plane defined by the nozzles. The steam jets are directed rearwardly into the containment chamber, so that they create a front-to-rear airflow between the intake and the exhaust vent. An instrument is positionable at the jet convergence point for cleaning. The airflow carries steam and airborne debris blasted from the instrument safely away from the user.

Abstract: There is provided a lacrimal fluid control device for blocking the flow of lacrimal fluid away from the surface of a wearer's eye through a punctal opening and into an associated caniculus. The lacrimal fluid control device includes a tip portion comprising a generally inverted truncated cone and a head portion comprising a generally enlarged dome. The tip is operable to facilitate placement of the lacrimal fluid control device at least partially through a wearer's punctal opening and the enlarged dome or head portion prevents drift of the lacrimal fluid control device completely through the punctal opening and into a generally vertical portion of an associated canaliculus.

Abstract: A punctum plug for blocking lacrimal fluid flow through a punctum and an associated canaliculus composed of a hydrogel material and a hydrophobic coating which covers the exterior surface of the hydrogel material. The hydrophobic coating averts adsorption of proteinaceous materials onto the hydrogel. The punctum plug has a configuration which includes a generally cylindrical body member, an arcuate head at a first end of the body member, and a placement and retaining member at a second, peripheral end of the body member. An insertion port is located at the first end of the cylindrical body member for receiving a dilator/inserter tool. A hydrating port is fashioned at the peripheral end of the plug and partially extends through the placement and retaining member. The hydrating port is not coated with the hydrophobic material so that fluid in the canaliculus, or canalicular fluid, or preocular tear film may enter the interior portion of the plug and permit the hydrogel to expand to a desired configuration.
