Cryopreserved endothelial cell survival in vivo

Area of Science:

• Ophthalmology
• Transplantation Biology
• Cryobiology

Background:

• Corneal transplantation is a common procedure to restore vision.
• Preservation of donor corneal tissue is crucial for successful transplantation.
• Cryopreservation offers a potential method for long-term storage of corneal tissue.

Purpose of the Study:

• To evaluate the survival and integrity of the endothelium in cryopreserved corneal transplants.
• To assess the clinical viability of cryopreserved endothelial cells after penetrating keratoplasty.

Main Methods:

• Observation of corneal transplant endothelium using clinical specular microscopy.
• Regular examinations conducted from one day to two months post-keratoplasty.

Main Results:

• An intact endothelial mosaic was consistently observed throughout the examination period.
• Demonstrated survival of cryopreserved endothelial cells in the transplanted cornea.

Conclusions:

• Cryopreserved endothelial cells remain viable after penetrating keratoplasty.
• Cryopreservation is a feasible method for preserving corneal endothelium for transplantation.
