keratophakia

keratophakia

 [ker″ah-to-fa´ke-ah] keratoplasty in which a slice of donor's cornea is shaped to a desired curvature and inserted between layers of the recipient's cornea to change its curvature.

ker·a·to·phak·i·a

(ker'ă-tō-fak'ē-ă), Implantation of a donor cornea or plastic lens within the corneal stroma to modify refractive error. Synonym(s): keratophakic keratoplasty [kerato- + G. phakos, lens]

keratophakia

(kĕr′ə-tō-fā′kē-ə)n. Keratoplasty in which corneal tissue from a donor is frozen, reshaped, and transplanted into the corneal stroma of the recipient to modify refractive error.

ker·a·to·phak·i·a

(ker'ă-tō-fā'kē-ă) Implantation of a donor cornea or plastic lens within the corneal stroma to modify refractive error. [kerato- + G. phakos, lens]

keratophakia

A method of altering the refractive power of the CORNEA, as by introducing an artificial lens or a lens-shaped piece of donated cornea between its layers.

keratophakia

A surgical procedure on the cornea aimed at correcting ametropia. A donor corneal disc (or lenticule) that was previously frozen and reshaped is inserted into the host cornea to modify the anterior corneal curvature. There are many complications and technical difficulties associated with this procedure. Syn. refractive keratoplasty and keratorefractive surgery (both terms also include epikeratoplasty, keratomileusis and radial keratotomy). See epikeratoplasty; Intacs; keratomileusis; photorefractive keratectomy; LASIK; LASEK; lenticule.
