Advantages and Disadvantages of Prostho-Keratoplasty by Using of Cardona's Bolt and Nut Model

• Kim JH

Abstract

The idea of replacement for opaque cornea by using of artificial material such as a transparent glass piece is an old thinking since year of 1777(Pellier de Quengsy). But the active researches on the concept of artificial corneas as an optical property were stimulated since the synthesis of plastic polymers and its application to medical use during the past 30 years. In year of 1964, Dr. Hernando Cardona1) designed his first prototype by using pure methyl methacrylate and/or with autologous unguinal material for an interlamellar supporting plate. By the way, Strampelli (1964) also has designed his osteo-odonto-kerato-prosthesis for same purpose, with another attempt of arthrochondro-keratoplasty in few years later. And Hayano (1969) also has designed a through and through type with methylmethacrylate. Since year of 1980, author has experienced clinically on prostho-keratoplasty by using Cardona's bolt and nut model, which has a flexible perforated retention nut plate in 26 consecutive patients.
