Book Cover & Preview Text
Results Keratoprostheses were placed in one eye in each of ten cats. Nine of the implants were retained for the duration of the study. The prostheses were well accepted by the corneas and were well centered within the limbus. There was a rapid decrease of swelling and inflammation in the conjunctival flap. Two cats developed retraction of the conjunctiva from the core requiring repair, one each at the fourth and eighth weeks. Both repairs were successful in obtaining conjunctival coverage of the cornea for the duration of the study.

About the Book
Dr. Barber gives a comprehensive review of previous keratoprostheses with their good and bad characteristics. From the results of this review, he designs a new prosthesis that incorporates the elements that have been shown to enhance the visual results and retention qualities of keratoprostheses. This prosthesis was tested in cat corneas and the dramatic results are reported.
About the Author
DR. BARBER spent a career in academic ophthalmology. During his fellowship in corneal diseases at Massachusetts Eye and Ear Infirmary in Boston, he began working with corneal prostheses. He has conducted research on collagenase inhibition, serum anti-proteases in the cornea and the development of an effective corneal prosthesis. These fields have all come together in this book which describes the development of a keratoprosthesis. He has implanted more than sixty prostheses in cat eyes.
He is a charter member of the Keratoprosthesis Study Group and has attended meetings of the group in the United States and Europe. Dr. Barber has published over seventy articles and abstracts in scientific journals including several concerning the development of keratoprostheses.
During eighteen years at the University of Texas Medical Branch, nine as Chairman of the Department of Ophthalmology, and twelve years as chairman at the St. Francis Medical Center he saw many patients who needed a keratoprosthesis for diseases including Ocular Cicatricial Pemphigoid, Stevens Johnson Syndrome, alkali burns, severe dry eyes, and amoebic keratitis. He ran residency programs at both institutions and trained over ninety ophthalmologists.
Dr. Barber is now retired from medical practice and is living with his wife, Dolores, in Pittsburgh, Pennsylvania and Venice, Florida. He writes books on patient care, gardens in the back yard, and travels extensively. He enjoys classical music and has performed supernumerary roles as part of his interest in opera. He is an avid golfer and enjoys sailing cruising sized sailboats.
