• thickness
  • A partial thickness flap with its base at the corneoscleral junction is then made in the sclera after careful cauterization of the flap area, and a window opening is created under the flap with a Kelly-punch to remove a portion of the sclera, Schlemm's canal and the trabecular meshwork to enter the anterior chamber.

  • laser
  • Therefore, in July 1985, he applied for a patent that described a method of modifying corneal refractive errors using laser ablation under a corneal flap. (wikipedia.org)
  • Since he had purchased an Erb-Yag laser in the U.S., he evaluated the concept using this laser in vivo in rabbit and primate eyes and described the creation of a hinged corneal flap to enable the ablation to be performed on the exposed corneal bed, thus reducing the potential for postoperative scarring and pain.
