Abstract: An apparatus for use with rechargeable dispensers includes a spray head and a probe connected to the spray head for puncturing reservoirs of concentrated chemical. The probe includes a connecting portion for attaching the probe to the barrel of the spray head; a disc portion, the connecting portion and the disc portion defining a through hole; and a shaft portion connected to the disc portion at one end and defining a tip end at another end. The probe may also include more than one shaft portion. In one embodiment, a conventional downtube is modified to function as a probe.

Abstract: A method of changing the shape and/or size of an intracorneal ring in situ. The intracorneal ring can be a lens. Preferably, the intracorneal ring is made of a collagen-based polymer material such as COLLAMER.

Abstract: Rechargeable containers and dispensers, in particular spray bottle dispensers including at least one chemical reservoir for recharging the spray bottle dispenser. Preferably, a plurality of separate chemical reservoirs containing chemical concentrate are provided within the spray bottle dispenser to fully contain any inadvertent spillage of chemicals, and to insure a high degree of safety against accidental spills, and/or accidental ingestion by children.

Abstract: A hingeless type intraocular lens microcartridge for use with a surgical insertion instrument. The hingeless microcartridge has a fixed configuration with a transition portion extending between a lens receiving portion and a nozzle portion.

Abstract: A dispensing apparatus including a spray bottle dispenser including a bottle portion and a spray head portion and a frame portion connecting said dispenser to a surface contacting portion and configured such that when said dispensing apparatus is in an upright position, said surface contacting portion is located above and in front of a nozzle portion of said spray head portion.

Abstract: Liquid dispensing devices provided with tilting or bending pickup tubes for allowing substantially complete evacuation of the contents of the supply bottles. In preferred embodiments, the pickup tube is connected to a dispensing unit such as a sprayhead by a variety of different types of flexible connectors to allow tilting of the pickup tube. In other preferred embodiments, a semi-flexible pickup tube is weighted to cause bending of the tube with or without the addition of a flexible connector between the pickup tube and sprayhead.

Abstract: A deformable intraocular lens injecting apparatus including a spring biased plunger. A preferred embodiment of the lens injecting apparatus includes a separate lens injecting device having a lens cartridge receiver, and a separate one-piece lens cartridge having a lens holding portion connected to a nozzle portion. The lens cartridge is preferably connected into the lens cartridge receiver by a bayonet-type connection.

Abstract: A biological material is prepared for use in ophthalmology by steps of providing animal pericardium, subjecting the animal pericardium to multiple steps of freezing and thawing in a salt solution and incubating the animal pericardium in a solution of ammonia and ethyl alcohol. The multiple steps of freezing and thawing are conducted in a mixture of about 0.9% sodium chloride solution and distilled water in about 1:1 proportions of sodium chloride solution to distilled water. The incubating step is conducted in a mixture of 1% ammonia solution and 1% ethyl alcohol solution in about 1:1 proportions of ammonia solution to ethyl alcohol solution over a period of 48 to 72 hours.

Abstract: A deformable intraocular lens injecting apparatus having a movable plunger with a deformable plunger tip, preferably a resiliently deformable plunger tip. In a preferred embodiment, the plunger tip is made of soft resiliently deformable material to prevent any surface or internal damage to the deformable intraocular lens being forced through a delivery passageway of the lens injecting apparatus.

Abstract: A phacoemulsification apparatus including a personal computer for displaying, storing and transmitting data relating to a surgical operation. Preferably, the personal computer is operated by MICROSOFT WINDOWS 95 or 98 software to take advantage of various communication applications.
