A microkeratome and method for performing lamellar keratoplasty is disclosed. The microkeratome consist of a cutting blade with a curved sharp edge. In surgery, a programmed curved guide rail is utilized to guide the cutting blade to move along a programmed curved path so that achieve a near spherical curved cutting pathway so as to cut the cornea in near its original un-flattened normal position. The microkeratome for performing lamellar keratoplasty includes a vacuum suction ring with guide rails, a cutting head assembly with a cambered cutting blade and curved front press and curved rear press. By controlling the internal components of the tool so that the vacuum suction ring can fix an eyeball. The microkeratome cuts cornea along a preset path of tracks, since the cutting blade is curved and the front press and rear press are also curved surfaces so that the cutting path is formed with a curved surface, thereby the microkeratome can cut in a path that keep the cornea remain in an un-flattened original position, thus reduce the deformity that in prior art plane cut will induce.
