Abstract

A successful keratoplasty is no longer measured only by the presence of a clear, healthy corneal graft. Corneal surgeons are now faced with the challenge of addressing post-keratoplasty astigmatism, which is the most important contributor to poor visual outcome after an otherwise successful corneal transplant. This chapter will discuss surgical options for astigmatism correction after keratoplasty. We will start by outlining the epidemiology of corneal transplants, astigmatism, and the combination of the two. Comparison of surgicaloptions will compromise the bulk of our discussion. Surgical options allow for correction of higher degrees of astigmatism than glasses or contact lenses. Astigmatic keratotomy, photorefractive keratectomy and laser in situ keratomileusis will be compared and contrasted. These methods differ in the amount of astigmatic correction that can be achieved, as well as their ability to predict this amount. They also differ in their rate of haze formation and their ability to address the spherical component of visual acuity. The pros and cons of each technique will be discussed and presented.
