Protection of the iris by lamellar dissection of corneal layers. A technique in penetrating keratoplasty

Cornea. 1994 Jan;13(1):16-9. doi: 10.1097/00003226-199401000-00004.


Adherent leukomatous corneal opacities constitute the bulk of cases undergoing keratoplasty in developing countries. Surgical trauma to the iris resulting in a large iris coloboma, iridodialysis, and bleeding are the imminent intraoperative complications in such cases. We have evolved a technique of lamellar separation of corneal layers and gentle separation of adherent iris after partial trephination in such cases. We have successfully used this technique in six cases of adherent leukoma. No intra-or postoperative complication related to lamellar separation was encountered, and all the grafts remained clear at the end of 3 months.
