Lamellar techniques have almost entirely replaced penetrating keratoplasty. They have undergone progressive refinements and have more recently evolved toward minimizing the presence of allogenic tissue in the eye to prevent rejection and graft failure.
“Overall, if we can work toward smaller grafts or no graft at all, this is going to benefit the patient in many ways. On the other hand, if we can multiply the number of grafts we can obtain from the same donor, we can reduce the costs and the problem of tissue shortage in some areas of the world,” Gerrit Melles, MD, PhD, said.
