Abstract
INTRODUCTION: Outcome of a corneal transplant surgery mainly depends on the functional reserve of the cornea being transplanted. Thus Donor corneal tissue evaluation forms a vital step in assessing the viability of the graft. Cornea retrieval can be done as an in situ corneal button excision or whole globe enucleation. Studies have shown that enucleation causes less corneal damage and striae as compared to in situ Corneo scleral button excision.1 As soon as the eye is received at the eye bank corneal evaluation is done by corneal surgeon using slit lamp and specular microscope, and the cornea is graded, labeled and sent for storage. Before evaluation, cornea should be allowed to come to room temperature. Whole globe or corneo sclera button should not be left at room temperature for more than one hour.
