角膜切割器是一个带有震荡刀片，用于在LASIK或ALK手术中制造角膜瓣的手术器械。常人的角膜厚度在500微米到600微米之间；在LASIK手术中 ， 角膜切割器会制造一个83微米到200微米厚的角膜瓣。该仪器由Jose Barraquer在1950年代在哥伦比亚发明，目前在全世界范围内被广泛使用。

A microkeratome is a precision surgical instrument with an oscillating blade designed for creating the corneal flap in LASIK or ALK surgery. The normal human cornea varies from around 500 to 600 micrometres in thickness; and in the LASIK procedure, the microkeratome creates an 83 to 200 micrometre thick flap. This piece of equipment is used all around the world to cut the cornea flap. It was invented by Jose Barraquer and Cesar Carlos Carriazo in the 1950s in Colombia.
