Surgical advances and results of keratoconus

We analyzed 82 eyes of 53 patients who underwent penetrating keratoplasty for keratoconus. Despite meticulous attention to microsurgical technique, and the use of the corneal punch. 10-0 monofilament nylon double continuous suture, and the surgical keratometer, and sizing the donor graft to recipient bed, we found a postoperative astigmatism of about 4.0 diopters. The percentage of clear grafts is now high and the complication rate low. However, we still have not developed a technique that ensures an anastigmatic cornea after keratoplasty for keratoconus.
