CORNISOL is a corneal storage solution for storage of human cornea suitable for keratoplasty for up to 14 days under refrigeration (2-8°C).
Device Description
Cornisol is a sterile hypothermic corneal storage medium intended for human corneal storage between 2 and 8℃ for up to 14 days. Cornisol is for single use and to be used only by physicians or highly skilled personnel such as eye bank operators. Corneas are directly placed in Cornisol medium after surgery with a storage time based on the time needed to obtain serology results of the donor but for a period of time of no more than 14 days.
More Information

No
The document describes a corneal storage solution and its performance studies, with no mention of AI or ML technology.

No.
The device is a storage solution for corneas intended for transplant, not a device used in the direct treatment or diagnosis of a condition in a patient.

No

Explanation: This device is a corneal storage solution, meaning it is used to preserve human corneas for transplantation. It does not perform any diagnostic function, such as detecting or identifying a disease or condition.

No

The device is a corneal storage solution, which is a physical substance (liquid medium) and not software.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • Intended Use: The intended use is for the storage of human corneas for transplantation. It is a preservation solution, not a device used to perform a diagnostic test on a sample taken from the human body.
  • Device Description: The description reinforces that it's a storage medium.
  • Lack of Diagnostic Function: There is no mention of the device being used to analyze a sample, detect a condition, or provide diagnostic information. The performance studies focus on the preservation quality of the cornea, not on diagnosing anything.
  • Testing: The testing described is related to the efficacy of the storage solution in maintaining the viability and integrity of the cornea, not on its ability to perform a diagnostic test.

IVDs are typically used to examine specimens (like blood, urine, tissue) to provide information about a person's health status, diagnose diseases, or monitor treatment. This device's function is entirely focused on preserving a biological tissue for later use in a surgical procedure.

Device Description

Cornisol is a sterile hypothermic corneal storage medium intended for human corneal storage between 2 and 8℃ for up to 14 days. Cornisol is for single use and to be used only by physicians or highly skilled personnel such as eye bank operators. Corneas are directly placed in Cornisol medium after surgery with a storage time based on the time needed to obtain serology results of the donor but for a period of time of no more than 14 days.

Cold storage of cornea is traditionally performed by keeping corneas in a cold storage medium containing deswelling agent(s) between 2°C and 8°C.

CORNISOL is a sterile, buffered corneal preservation medium comprised of the ingredients shown in Table 1. It is supplied ready to use with a volume of 20 mL in a 20 mL type 1 glass vial with a polyethylene cap and PVC shrink wrap.

Summary of Performance Studies

Cornisol has undergone various testing including physicochemical testing, microbiological testing, sterilization validation, stability (shelf-life), packaging integrity testing as well as biocompatibility and in vitro testing.

The Cornisol formulation was tested in two in vitro studies. The first was a prospective, in vitro, randomized study using paired donor corneas was performed. The assessments to determine equivalent performance were endothelial cell loss, endothelial cell density (ECD), coefficient of variance, and percentage hexagonality on days 3, 7, 10, and 14. The results indicated that Cornisol adequately preserved the cornea for up to 14 days in storage. The second study was on donor corneas to compare the structural and functional integrity of the donor corneas following storage in Cornisol or Optisol-GS. Corneas were immunostained for markers of structural integrity (ZO-1, Phalloidin) and functionality (Na+/K+ ATPase). The results indicated that Cornisol had similar performance in preserving cell structural integrity and functionality.

Performance Data

Cornisol has undergone various testing including physicochemical testing, microbiological testing, sterilization validation, stability (shelf-life), packaging integrity testing as well as biocompatibility and in vitro testing.

Chemical characterization to assess the biocompatibility profile of the corneal storage media and primary packaging was conducted. The selected ingredients are commonly used in corneal storage media and no novel ingredients were selected. Cornisol is a buffered corneal preservation medium that includes additives like buffering agents, osmotic agents and pH adjusters/indicators, and there are no residues and process contaminants present in the solution. In addition, Cornisol does not contain polymers, ceramics and metals in the formulation that would produce degradation products of this nature.

Cornisol is a solution that is manufactured and sterilized by sterile filtration using 0.2 micron polyether sulphone membrane filters. The filters have been validated for aqueous extracts to exhibit . A finished product endotoxin specification for Cornisol of 5 EU/device has been established and batch results confirm that Cornisol conforms with this specification.

Although Cornisol solution is sterilized by sterile filtration, the vial caps are sterilized by ethylene oxide (EO). The average daily exposure of EO to a patient shall not exceed 1.25 ug/device for EO and 5 µg/device for ECH (4 times EO limit), in compliance with the limits for IOLs in the ANSI/AAMI/ISO 10993-7:2008(R)2012 (Table C.1 in Annex C) standard. The shelf life for Cornisol is 12 months when stored at 2℃ to 8℃.

Package integrity testing is performed on every batch of packaging components (vial and caps) for Cornisol by dye ingress/egress vacuum testing to ensure that the components can maintain the sterile barrier. In addition, each batch of Cornisol finished product is also tested using inverted vacuum challenge testing. Representative samples of packaging components have been tested and these results confirm ability to maintain the sterile barrier.

In addition, biocompatibility testing of Cornisol has been conducted.

  • Cytotoxicity in accordance with ISO 10993-5 .

7

  • Sensitization in accordance with ISO 10993-10 .
  • . Acute ocular irritation testing in accordance with ISO 10993-10

The Cornisol formulation was tested in two in vitro studies. The first was a prospective, in vitro, randomized study using paired donor corneas was performed. The assessments to determine equivalent performance were endothelial cell loss, endothelial cell density (ECD), coefficient of variance, and percentage hexagonality on days 3, 7, 10, and 14. The results indicated that Cornisol adequately preserved the cornea for up to 14 days in storage. The second study was on donor corneas to compare the structural and functional integrity of the donor corneas following storage in Cornisol or Optisol-GS. Corneas were immunostained for markers of structural integrity (ZO-1, Phalloidin) and functionality (Na+/K+ ATPase). The results indicated that Cornisol had similar performance in preserving cell structural integrity and functionality.

Conclusion

Cornisol is substantially equivalent to the predicate device, Optisol-GS. There are not different questions of safety and effectiveness with respect to the intended use and technologically characteristics between Cornisol and the predicate device.
