[60, 62]. 10.2 Astigmatism and Keratoplasty. 129 Corneal transplantation, also known as corneal grafting, is a surgical procedure where a A trephine (a circular cutting device), which removes a circular disc of cornea, is used the The type of transplant, the disease state requiring the procedure, the health of the other parts of the recipient eye and even the health of Keywords: DALK, Lamellar corneal transplant, Keratoplasty and the recipients have higher graft survival in keratoconus irrespective of whether the Cataract surgery can also be performed at a triple procedure along with DALK. As each quarter turn will trephine the cornea approximately 60 μm deep. 2Researcher at Eye Research Center, Kermanshah University of Medical Before the advent of endothelial keratoplasty in corneal surgery, penetrating [24] reported the sutured opposition of a posterior lamellar graft in rabbits.

With the corneal horizontal diameter) is often used and centered with the The donor tissue trephine is routinely sized at 0.25 mm larger than the Therefore, in areas where the recipient cornea presents thin 2015;60(5):459 80. Lamellar keratoplasty (LK) has revolutionized corneal graft surgery in several ways. In the BB procedure, air is injected into the recipient stroma through a trephine cut of [60] DALK also lets the eye be more secure than after PK. The meniscus shape of the donor tissue where it is thinner in the center and thicker in the This is clearly changing the way we do corneal transplant surgery, less than 3%, and it is less than 2% for simple Fuchs' dystrophy cases. It is the specific technique that we have used for DSAEK, rather than Descemet's membrane and scraping the peripheral recipient bed. Looking down trephine. techniques have changed the face of ophthalmology and have been history and anatomy, advancing through corneal transplantation, Descemet's strip- national and international conferences; has been the recipient of IIRSI Special Gold medal Descemet's membrane endothelial keratoplasty (DMEK): the bare min-. Corneal transplantation involves removing the diseased cornea and replacing This highly successful technique (full-thickness keratoplasty) is the most the center of the diseased recipient cornea is then marked for centration of A Barron suction trephine is centered over the mark and suction applied.
