A novel technique for harvesting keratolimbal allografts from corneoscleral buttons AMERICAN JOURNAL OF OPHTHALMOLOGY Aldave, A. J., Wong, I. G. 2002; 134 (6): 929-931

Abstract

To describe a method for obtaining partial-thickness keratolimbal allografts from corneoscleral buttons to be used in corneal limbal stem cell transplantation.Description of device design and technique for use.Cyanoacrylate tissue adhesive, placed on the posterior side of a trephinated corneoscleral rim, is used to secure the allograft to a disposable acrylic sphere that is attached to a cylindrical base.After fixation of the corneoscleral rim to the acrylic sphere, keratolimbal allograft harvesting is performed as a continuous strip dissection with a 65 Beaver blade. This technique minimizes trauma to the epithelial stem cells, provides excellent stability of the corneoscleral rim during harvesting, and preserves the central corneal button.This method for obtaining keratolimbal allografts effectively provides tissue stabilization during harvesting, minimizing epithelial stem cell trauma and eliminating the need for whole donor globes.
