Risk Factors for Failure of Keratoplasty in Keratoconus: Penetrating vs. Deep Anterior Lamellar Keratoplasty

Purpose: To determine the etiologic factors on rejection and failure rates and ocular surface changes after corneal transplantation by either DALK or PKP, in cases of keratoconus (KCN). Methods: In this cross-sectional study, considering the existing data, patients with keratoconus referring to Labbafinejad Medical Center from 2006 to 2016, who underwent corneal transplantation, were enrolled a...

Anterior Lamellar Keratoplasty

lar keratoplasty is not new. Mühlbauer was the first to describe a technique for anterior lamellar keratoplasty (ALK) in 1840.1 Penetrating keratoplasty (PKP) has long been the standard treatment for severe corneal pathology. Lamellar surgery has endured significant technical challenges since its inception. The posterior corneal surface is invisible through an operating microscope, due to the s...

Sutureless Lamellar Keratoplasty

Purpose To determine whether a fibrin adhesive can facilitate the performance of sutureless lamellar keratoplasty and attachment of amnion to bare sclera.

Rectangular Autogenous Lamellar Keratoplasty.

MANY of the stationary corneal opacities causing diminution of vision are central, avascular, and superficial, and are surrounded by clear cornea or have a neighbouring peripheral clear corneal area of 4 x 4-5 mm. Donor homogenous corneal grafts are not always available, but a rectangular lamellar autogenous corneal. graft can be dissected and turned 1800 so that the clear lamellae are brought ...
