Simple corneal lamellotome for keratoplasty.

THE cutting of corneal lamellae for keratoplasty of a given thickness is laborious and by no means easy in the absence of abundant experience. Some devices for such procedures, such as Bock"s corneal knife, do not permit of sufficient accuracy, and the electric keratotome of Castroviejo is a very costly instrument. The simple and inexpensive device described below enables one to obtain a corneal lamella of any desired thickness, with a reasonable assurance of uniformity throughout.
