Tectonic Deep Anterior Lamellar Keratoplasty in Impending Corneal Perforation Using Cryopreserved Cornea
We report a case of tectonic corneal transplantation for impending corneal perforation to preserve anatomic integrity using cryopreserved donor tissue. An 82-year-old woman exhibiting impending corneal perforation suffered from moderate ocular pain in the left eye for one week. After abnormal tissues around the impending perforation area were carefully peeled away using a Crescent blade and Van...
متن کاملTectonic Lamellar Keratoplasty Using Cryopreserved Cornea in a Large Descemetocele
We describe herein a case of an impending corneal perforation with a large descemetocele in a patient with previous penetrating keratoplasty (PKP) that subsequently was treated with an emergent lamellar keratoplasty using frozen preserved cornea. A 76-year-old male patient, who had a PKP, presented with a completely whitish and edematous graft accompanied by large epithelial defects. Although a...
متن کاملdescemet-on versus descemet-off donor cornea for deep anterior lamellar keratoplasty
purpose: to determine the effect of retained donor descemet membranes (dms) on visual outcomes following deep anterior lamellar keratoplasty (dalk). methods: in this retrospective comparative study, keratoconic eyes undergoing dalk using the big-bubble technique were enrolled. a bared dm was achieved in all cases. a donor cornea without (group 1; 48 eyes) or with (group 2; 22 eyes) dm was sutur...
متن کاملRisk 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...
متن کاملDonor cornea preparation in partial big bubble deep anterior lamellar keratoplasty
BACKGROUND The purpose of this paper is to describe a technique of donor cornea preparation to ensure good graft-host apposition in incomplete big bubble deep anterior lamellar keratoplasty. METHODS Following a partial-thickness trephination, manual dissection and excision of corneal stroma was performed. Anwar's big-bubble technique involving a deep stromal air injection was then initiated. ...
