Corneal Topography in Management of PK Astigmatism

  • Chapter
Corneal Topography

Abstract

In 1869 Snellen1 suggested that a steep corneal meridian may be flattened by an interior corneal incision. Bates2, in 1984, correctly described the corneal topography result after circumferential corneal meridian perpendicular to the circumferential incision. He observe that the closer the incision is to center of the cornea, the greater the correction of astigmatism. He also noted the length and depth of the incision influence the change in radius of curvanture of the corneal meridian. In 1989, lans3 published his result on the series of experiment attempting to reduce astigmatism in rabbit cornea and describe a “double wedge resection” in the cornea (Fig.11.1).
