Abstract

The instruments required for lamellar keratoplasty are used to dissect the donor cornea as well as the recipient bed. Lamellar keratoplasty is not new concept. However, it had been abandoned and largely replaced by the time-honored technique of penetrating keratoplasty because lamellar keratoplasty is technically demanding, time consuming and gives suboptimal visual outcomes due to interface irregularity arising from manual lamellar dissection. Recent improvements in surgical instruments and introduction of new techniques of maximum depth of corneal dissection as well as inherent advantages such as preservation of globe integrity and elimination of endothelial graft rejection have resulted in a re-introduction of lamellar keratoplasty as an acceptable alternative to conventional penetrating keratoplasty.
