## Intended Use

LIFE4°C is indicated for storage of human corneas suitable for keratoplasty up to 14 days under refrigeration (2-8°C).

## Device Story

Life4°C is a sterile, non-pyrogenic, buffered corneal preservation medium used for the hypothermic storage of human corneas intended for keratoplasty. The solution contains a mixture of chondroitin sulfate, recombinant human insulin, Dextran, glutathione, L-glutamine, ATP precursors, nutrients, amino acids, vitamins, trace elements, gentamycin, streptomycin, and phenol red. It is supplied as a 30 ml single-use solution in a PETG bottle. The device is used in clinical or eye bank settings to maintain corneal viability for up to 14 days at 2-8°C. By providing a stabilized, nutrient-rich environment, the medium supports corneal tissue integrity prior to transplantation, potentially improving surgical outcomes for patients requiring keratoplasty.

## Clinical Evidence

No clinical data. Bench testing only, including long-term stability, safety testing, performance characteristics, sterilization validation, and package validation.

## Technological Characteristics

Sterile, non-pyrogenic, buffered aqueous solution. Components: chondroitin sulfate, recombinant human insulin, Dextran, glutathione, L-glutamine, ATP precursors, nutrients, amino acids, vitamins, trace elements, gentamycin, streptomycin, phenol red. Packaging: 30 ml PETG bottle with HDPE cap. Single-use. Storage temperature: 2-8°C.

Dear Ms. Freddo:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.

{3}------------------------------------------------

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
