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 cornea...

We present a simple, effective and reproducible technique for deep anterior lamellar keratoplasty. Using a diamond knife, set at 90% of corneal thickness (90 degrees meridian), at the limbus a radial incision was made and a corneal pocket was created. A specially designed cannula was placed deep into the corneal stroma and air was injected for stromal dissection. The air bubble pushed down Desc...
