keratoplasty /ker·a·to·plas·ty/ (ker´ah-to-plas″te) plastic surgery of the cornea; corneal transplantation.
keratoplasty [ker´ah-to-plas″te]
optic keratoplasty transplantation of corneal material to replace scar tissue which interferes with vision.
refractive keratoplasty removal of a section of cornea from a patient or donor, which is shaped to the desired curvature and inserted either between (keratophakia) layers of or on (keratomileusis) the patient's cornea to change its curvature and correct optical errors.
tectonic keratoplasty transplantation of corneal material to replace tissue which has been lost.
tec·ton·ic keratoplasty (t k-t n  k)n. The surgical grafting of corneal material in an area where corneal tissue has been lost. |
keratoplasty [ker´ah-to-plas″te]
optic keratoplasty transplantation of corneal material to replace scar tissue that interferes with vision.
refractive keratoplasty removal of a section of cornea from a patient or donor, which is shaped to the desired curvature and inserted either between layers of the recipient's cornea (keratophakia) or over the cornea (keratomileusis) in order to change the corneal curvature and correct optical errors.
tectonic keratoplasty transplantation of corneal material to replace tissue that has been lost.
keratoplasty
plastic surgery of the cornea; corneal grafting.
lamellar keratoplasty
a partial thickness graft of the cornea; only epithelium and superficial stroma is removed and replaced by donor tissue as distinct from penetrating or full-thickness grafting.
optic keratoplasty
transplantation of corneal material to replace scar tissue that interferes with vision.
penetrating keratoplasty
a full thickness of the cornea is removed and replaced with donor tissue.
tectonic keratoplasty
transplantation of corneal material to replace tissue that has been lost.
