The portion of the LASIK procedure in which the surgeon raises a thin layer of the cornea - creates a corneal flap - with an instrument called a microkeratome, (or Femtosecond laser) to expose the layer of the cornea called the stroma.
A rare inherited condition of the cornea in which the cornea is steepened to the point of being cone-shaped. Keratoconus is a form of Ectasia.
The carving of the cornea formerly done with a lathe and blade, now done with an excimer laser.
The replacement (transplantation) of the cornea. Keratoplasty can be lamellar (replacement of superficial layers) or penetrating (replacement of the full thickness of the cornea).
A surgical incision (cut) of the cornea.
The replacement of superficial layers of the cornea with the layers of another donor cornea.
An acronym for light amplification by stimulated emission of radiation. A medical instrument that produces a powerful beam of light and can produce intense heat or cool vaporization when focused at close range. Lasers are often used in surgery to remove tissue.
The acronym for laser assisted in situ keratomileusis. The name refers to the use of a laser to reshape the cornea without invading the adjacent cell layers. For more information, see Lasik Eye Surgery.
