A device for surgery of the cornea comprising: an annular base ( 100 ) for fixing the apparatus to the eye of a patient; a cutter head ( 200 ) comprising a body ( 200 a) and a blade ( 201 ) suitable for being displaced along a plane trajectory parallel to the annular base ( 100 ); guide means ( 106 ) for guiding the cutter head ( 200 ) relative to the base ( 100 ); drive means ( 302 ) for driving the blade ( 201 ) in the cutter head ( 200 ) with reciprocating linear motion parallel to its cutting edge ( 201 b); and drive means ( 303 ) for driving the cutter head ( 200 ) relative to the annular base ( 100 ) along said trajectory. Said drive means ( 302, 303 ) comprise two independent motor units surmounting the cutter head and having mutually parallel outlet shafts ( 306, 310 ) perpendicular to the plane of the trajectory of the cutter head ( 200 ). |
