Abstract
A corneal marker and a method of using a corneal marker are disclosed. The corneal marker includes a handle having a head coupled thereto. The inferior surface of the head includes a set of protuberances which form marking surfaces adapted to simultaneously engage corneal tissue. The marking surfaces form opposing sets of marks which allow a surgeon to form an incision of precise length and width. An alignment line on the superior and/or front surface of the marker facilitates the positioning thereof. A method of performing clear corneal surgery following the application of markings to the cornea is also provided.
