Surgical Correction of Astigmatism After Penetrating Keratoplasty

Chapter

Abstract

For many decades, penetrating keratoplasty (PKP) has been the procedure of choice for patients requiring surgical correction for a variety of corneal diseases resulting in a loss of optical clarity from trauma, infection, dystrophy, or significant irregularity due to ectasia. In recent years, there has been a move away from penetrating keratoplasty in favor of various endothelial keratoplasty (EK) techniques. EK procedures have now surpassed PKP procedures as the most commonly performed type of corneal transplant surgery. Additionally, there has been recent renewed interest in lamellar keratoplasty techniques such as DALK for anterior stromal dystrophy, opacity, and even ectasia. Nonetheless, there still remains a role, which will likely continue in the foreseeable future, for the use of penetrating keratoplasty.
