keratectomy

 [ker″ah-tek´to-me]
excision of a portion of the cornea; kerectomy.
photorefractive keratectomy a procedure to correct errors of refraction in the eye by using an excimer laser to remove a portion of the anterior part of the cornea, which changes the refraction by creating a new radius of curvature.

ker·a·tec·to·my

(ker'ă-tek'tŏ-mē),
An operation done to change the refraction of the cornea; a crescentic piece of corneal stroma is removed and the resultant corneal wound is sutured. This steepens the cornea and increases its power in that axis.
See also: keratotomy.
[kerato- + G. ektomē, excision]

keratectomy

/ker·a·tec·to·my/ (ker″ah-tek´to-me) excision of a portion of the cornea; kerectomy.
photorefractive keratectomy  the correction of ametropia by using an excimer laser to remove a portion of the anterior corneal stroma in order to create a new radius of curvature.

keratectomy

(kĕr′ə-tĕk′tə-mē)
n. pl. keratecto·mies
Surgical removal of a part of the cornea.

keratectomy

[ker′ətek′təmē]
Etymology: Gk, keras, horn + ektomē, excision
surgical removal of a part of the cornea, performed to excise a small, superficial lesion that does not warrant a corneal graft. Local anesthesia is used. The scar is excised, and an antibiotic is injected under the conjunctiva. A topical steroid is given and a light pressure dressing applied. After surgery, the dressings are changed daily. Corneal epithelium grows rapidly, filling a small surgical area in about 60 hours.

ker·a·tec·to·my

(ker'ă-tek'tŏ-mē)
An operation to remove corneal tissue.
[kerato- + G. ektomē, excision]

keratectomy

Surgical removal of part, or rarely all, of the CORNEA.

keratectomy

excision of a portion of the cornea; kerectomy.

superficial keratectomy
involves removal of the corneal epithelium and anterior stroma, on either a specified portion or the whole cornea.
