A hypodermic needle system and method for reducing the incidence of infections due to administering fluids by injection to humans or animals is provided. The hypodermic needle system may include a needle with an insert disposed within its hollow channel to substantially prevent bacteria, fungi and/or other organisms/contaminants, which may be present on the exterior surface to be penetrated, from adhering to the inner surfaces of the needle's channel or become trapped in the needle bore. The hypodermic needle system may include a film that covers at least one surface of the needle or insert, and/or have a bent or curved tip to reduce the ability of infectious agents to adhere to said surface/space within the needle. Additionally, the hypodermic needle system may include an anti-infection agent, such as an antibiotic or antiseptic to further reduce the incidence of infections, and may include an attachment member which reduces the risk of infection.

Apparatus for the removal of lens tissue includes a first instrument for inserting into a lens capsule and removing a cataract therein, the first instrument including a lumen for aspiration of cataract tissue and irrigation fluid from the lens capsule and manipulate the cataract until cataract is removed. The second instrument includes an irrigation port for introducing the irrigation fluid into the lens capsule.

Multi-functional second instrument for cataract removal

The device comprises a tubular housing having an axis and comprising a suction ring on its lower end face with an annular recess communicating with a corretor for connection to a suction pump. The housing has first stop means and second stop means. A tubular insert is mounted in the housing for rotation around the axis and axially displacable. The insert has a third stop means cooperating with the first stop means for defining an extended position of the insert and a fourth stop means coacting with the second stop means for defining a retracted position of the insert. The insert further has a micrometer female thread. A tubular knife holder with a knife for cutting a circular cut into the cornea is mounted in the insert. The knife holder has a micrometer male thread threaded into the female thread and a head. A scale and a marking on the head and on the insert are provided for preselecting a depth of the cut in the extended position of the insert.

Device for transplanting a cornea on a patient's eye

In accordance with the present invention, a composition is provided with Vitamins C and E, zinc acetate, copper, selenium, manganese, and at least one of L-cysteine, pyridoxine, and riboflavin. The Vitamins C and E serve as antioxidants, while the zinc acetate, copper, selenium and manganese serve as cofactors for metalloenzymes which scavenge oxidizers. The remaining three compounds tend to enhance glutathione concentration. All the elements are provided in a tablet or caplet form which is suitable for oral ingestion. Preferably, the composition is taken periodically each day of a treatment period.
