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

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

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.

One of the oldest technique used is Photorefractive keratectomy (PRK) in which the exclaimer laser directly sculpts the front surface of the cornea.
After the end of the keratectomy procedures and at 14 hours on the consecutive days, fluorescein was instilled on the corneas for evaluation with slit lamp (SL-15, Kowa Optimed Inc., Japan) and cobalt filter by the same blinded examiner.
If you have very thin corneas, you may need a refractive procedure such as photorefractive keratectomy (FRK) or laser epithelial keratomileusis (LASEK) instead of LASIK.

Two types of laser surgery-photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK)-are often used to correct refractive errors such as nearsightedness.
