Use of a Disposable Artificial Anterior Chamber for Trans-Epithelial Trephination and Endothelial Keratoplasty

The Barron artificial anterior chamber (Katena, Denville, NJ) is an innovative development in corneal transplant and lamellar surgery. The chamber is a specialized device that allows a donor corneoscleral cap of tissue to be anatomically positioned ‘‘epithelial side up.’’ The chamber is used to mount the donor tissue and maintain adequate pressure while lamellar dissection or full thickness trephination is being performed. The Barron artificial anterior chamber is designed in a bright blue color to provide a highcontrast background for visualizing the cornea and aiding in the lamellar dissection of the cornea. This innovative chamber is the only disposable artificial anterior chamber and provides many advantages to surgeons beginning to offer endothelial replacement surgery to their patients.
