WHEREAS perforating keratoplasty is becoming a common operation both in the United States and in Europe and gives satisfactory results in the hands of experienced ophthalmic surgeons, lamellar keratoplasty is not very popular in the New World. The experiences of my colleagues and myself with the latter operation are, however, so encouraging that I wish to draw attention to its wide field of indication and, in particular, to a new instrument which we have designed to facilitate the taking of the lamellar graft. We believe that this improvement of technic is to a great extent responsible for the satisfactory results we obtain.
It is an interesting fact that lamellar keratoplasty is often able to induce a clearing up of the surrounding opaque corneal tissue. Filatow1 (1937) therefore proposed it as a preliminary operation in cases of extensive corneal leukoma in which he later wanted to perform a perforating keratoplasty,
