摘要: A process for establishing functional human corneal tissue consisting of an enhanced contact-inhibited endothelial monolayer derived from isolated human corneal endothelial cells with other integral corneal layers remaining intact. The process is divided into four integral parts.1. Isolation of human corneal endothelial cells from donor corneas.2. Establishment of a human corneal endothelial cell line which involves the establishment of primary cell cultures, proliferation, and continued maintenance and subculturing of these cells in vitro.3. The utilization of long term storage of isolated human corneal endothelial cells at -80.degree. C.4. Utilizing these isolated corneal endothelial cells from the above processes to enhance the corneal endothelial monolayer of human donor corneas to be used for penetrating keratoplasty.Two distinct methods of corneal endothelial enhancement may be utilized. In the first method, isolated human corneal endothelial cells are incorporated into the existing donor monolayer and re-establish a contact-inhibited functional monolayer, with a flattened, hexagonal configuration. In this procedure, the donor corneal endothelium remains intact and is supplemented with additional corneal endothelium. In the second method, isolated human corneal endothelial cells are seeded onto a denuded Descement's membrane and re-establish an intact cellular matrix, and form a contact-inhibited functional endothelial monolayer. In this procedure, the donor corneal endothelium is completely removed and replaced with new endothelial cells.

摘要: A corneal holder, amenable for use in both a corneal storage system and a corneal cutting system with minimal physical manipulation of the corneal tissue itself. The holder provides a passageway through the apertures of both a base member and a cap member that is configured to allow a cutting device to be passed into cutting contact with a predetermined portion of the corneal tissue. The holder allows radial orientation of the predetermined portion in order to limit astigmatism; as well as constriction of the periphery of the corneal tissue during storage in order to alleviate swelling of the tissue due to fluid absorption.

摘要: This is a non-primate vitreal replacement process that quantitates the inflammatory response to viscoelastic agents or solutions. More specifically, the rabbit vitreal replacement process consists of the surgical replacement of a small volume of the central gel vitreous of the rabbit with a viscoelastic agent or solution, and measuring the invasion of white blood cells in the vitreous and anterior chamber at 48 hours post injection. Additional parameters measured are anterior chamber flare, haze and flare in the vitreal chamber, ocular fundus clarity, presence of iris congestion, lens involvement, corneal clarity, conjunctival congestion and conjunctival swelling. In this process, the rabbit is evaluated prior to injection of the viscoelastic agent or solution and 48 hours post injection. Each parameter is evaluated on a scale of 0 to 5. A non-inflammatory sample consists of a mean total score of equal to or less than one or a vitreal cell count less than 50 cells/mm.sup.3. This is an extremely sensitive system for detecting small amounts of inflammatory agents in viscoelastic agents or solutions. The test solution is rated as acceptable for veterinary or human use if a non-inflammatory response is obtained in this process.
