Penetrating keratoplasty for keratoconus: visual and graft survival outcomes.
OBJECTIVES To evaluate the complications, and visual and graft survival outcomes in eyes that had undergone penetrating keratoplasty (PKP) for keratoconus. METHODOLOGY This restrospective study includes 311 patients with keratoconus who had undergone PKP between January 1, 2001, and December 31, 2002, at King Khaled Eye Specialist Hospital.

Neovascularization is defined as formation of new vessels from vascular endothelial cells derived from existing blood vessels. These new immature vessels are friable. They have increased permeability, lack structural integrity, and can result in lipid deposition and corneal opacities. Ultrastructurally, corneal neovascularization is characterized by vessels encroaching through separated stromal...
متن کاملGlaucoma after penetrating keratoplasty
Penetrating keratoplasty is a surgical intervention that despite the progress of surgical techniques and of postoperative treatment continues to have numerous complications. Many of them, such as graft rejection, significant astigmatism, cystoid macular edema, or cataract lead to important limitations of the visual function. Glaucoma is possibly the most dangerous complication following PK, lea...
متن کاملDisposable graft splint in penetrating keratoplasty.
Jones and Rice (I968) have demonstrated experimentally that the endothelium of the donor corneal disc may be subjected to considerable mechanical trauma during penetrating keratoplasty by the more commonly used techniques. From these experimental observations they have developed a method in which the corneal disc is sutured over a cushion of air, thus obviating much of the endothelial trauma in...
