keratotomy

Any surgical cut (incision) into the cornea. Radial keratotomy is an operation purporting to reduce short-sight (MYOPIA) by inducing scarring to flatted the cornea. Eight or more deep radial cuts are made. The operation is of dubious propriety and is being replaced by less crude methods.

keratotomy

multiple punctate keratotomy
multiple, non-penetrating punctures of the corneal stroma to stimulate healing of refractory or recurrent corneal erosions.

Which one of the following is incorrect regarding radial keratotomy (RK)?
This formed the basis of a technique known as radial keratotomy (RK), (3) which became popular for a few years before excimer laser eye surgery took the world by storm.
In this interesting Connecticut case, one individual responded to an ophthalmologist who advertised and provided radial keratotomy.
Refractive surgery is relatively new (1980s and 1990s), having begun with radial keratotomy and progressed through photorefractive keratectomy to laser-assisted in situ keratomileusis (LASIK), although these procedures are performed in outpatient laser centers or in the ophthalmologist's office.
McDonald started performing refractive surgery -- such as RK, radial keratotomy, where microscopic incisions are made around the center of the cornea to treat nearsightedness -- about a decade ago.
In ever-expanding numbers, adults with poor vision are having their corneas reshaped through refractive surgical procedures such as radial keratotomy, or RK, photorefractive keratectomy, or PK, and laser-assisted in situ keratomileusis, or LASIK.
Implants would serve as a less permanent alternative to corrective surgical techniques such as radial keratotomy or photorefractive keratectomy.
It differs from excimer laser procedures such as Photorefractive Keratectomy (PRK), Laser-Assisted Instrastromal In Situ Keratomileusis (LASIK), and traditional incisional surgeries such as Radial Keratotomy (RK) because no incisions or laser ablations are used to cut or irretrievably remove corneal tissue; and from Intra Corneal Ring (ICR) and Intraocular Lens (IOL) procedures because nothing is inserted into the eye.
Approved procedures include radial keratotomy (RK), photorefractive keratectomy (PRK), laser-assisted in-situ keratomileusis (LASIK) and more recently, intra-corneal rings.
Radial Keratotomy (RK), Astigmatic Keratotomy (AK), and Automated Lamellar Keratoplasty (ALK), are commonly performed procedures selected by people who want to be less dependent on glasses or contact lenses for the correction or improvement of myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
The oldest type of refractive surgery, called radial keratotomy (RK), has been used in the United States for more than 15 years.
