Apparatus for lamellar keratoplasty

摘要

A microkeratome for improved corneal flap production for corneal surgery. The microkeratome, having a first aperture and a cutting blade, includes a second aperture located just below the plane of the cutting blade and through which a corneal plug protrudes in preparation for the lamellar cut of the microkeratome to create a uniformly thick lamellar flap of predetermined diameter and depth. The second aperture can include a second cutting blade. The microkeratome also includes a transparent applanation plate positioned at a predetermined distance above the plane of the cutting blade and an adjustable stop to prevent complete transection of the corneal flap.
