Prognostic factors for corneal graft recovery after severe corneal graft rejection following penetrating keratoplasty

BACKGROUND To investigate the outcome and prognostic factors for corneal graft recovery after severe corneal graft rejection following penetrating keratoplasty (PKP) treated with topical and systemic steroids. METHODS Fifty-eight eyes in 58 patients with severe corneal graft rejection following PKP were treated with topical and systemic steroids. Factors affecting the reversibility and mainte...

[Suitability of newborn donor corneal graft in penetrating keratoplasty].

OBJECTIVE The lower recommended age of the donor cornea is a controversial matter. Although newborn corneas have a high endothelial cell density, there are anatomical, refractive (myopic shift) and postoperative problems. Two cases are analyzed; one had an atypical refractive result and the other an unexpectedly severe immune response. We also review the use of pediatric donor corneas in penetr...

corneal graft biomechanics after penetrating keratoplasty in keratoconus

purpose: to evaluate corneal hysteresis and corneal resistance factor in penetrating keratoplasty grafts in a group of keratoconic eyes using the ocular response analyzer (ora) and to evaluate the relationship between donor size, donor-recipient disparity and central graft thickness (cgt), and ora parameters. methods: this cross-sectional study was conducted on 34 eyes of 34 keratoconus patient...

Corneal trephining for penetrating keratoplasty.

MANY complications following corneal grafting procedures may be attributed to the technical and biological problems associated with this type of surgery. It is generally agreed that accurate apposition of the graft to the margin of the incision in the recipient cornea is of the greatest importance. Manual trephining for penetrating keratoplasty frequently results in badly cut grafts, and for th...
