refractive surgery

Ophthalmology Any technique that corrects myopia by changing the cornea's conformation Types Radial keratectomy–incisions are made at the periphery of the cornea, flattening and weakening it; photoreactive keratectomy–cornea is photoshaved with a laser in concentric circles, which imparts homogenous consistency. See PhotoRadial keratectomy.

refractive surgery

An operation to improve the ability of the eye to focus and thus to eliminate the patient's need for eyeglasses. Examples include keratoplasty and keratomilleusis.

Refractive surgery

A surgical procedure that corrects visual defects.

refractive surgery 

Surgical procedure aimed at correcting ametropia. Most procedures are performed on the cornea, but some involve either an intraocular lens implant, or more rarely crystalline lens extraction. See epikeratoplasty; Intacs; keratomileusis; keratophakia; photorefractive keratectomy; LASIK; LASEK.

A study with this same approach, carried out by Savini and coauthors in Italy, found that the difference between the simulated keratometry values (SimK), calculated with Sirius[R] corneal tomograph (CSO-Costruzione Strumenti Oftalmici, Florence, Italy), before and after refractive surgery, underestimated the refractive change after the myopic correction and overestimated it after the correction of hyperopia.

Different procedures have been used in refractive surgery which include photorefractive keratectomy (PRK), radical keratotomy (RK), laser-assisted in situ keratomileusis (LASIK), laser thermal keratoplasty (LTK), small incision lenticule extraction (SMILE) etc.4 Refractive surgeries with laser flap makers were approved by the United States Food and Drug Administration (FDA) in 1999 and femtosecond specifically for flap creation was approved in 2001.5 Femtosecond laser-assisted LASIK (femto-LASIK) is very successful latest innovation in refractive surgery because of its better outcome, long-term stable results, and lesser complications compared to other procedures.6 Femtosecond uses ultra-short duration of the pulses (10-15) causing significantly less damage to the collateral tissues.

Recent introduction of wavefront guided modalities like wavefront optimized and customized surgery has been claimed to improve the postoperative visual outcome after laser refractive surgery because they not only correct the refractive error but also decrease the HOAs.
These include cataract and lens-based refractive surgery, treating patients with cataracts, as well as those who are short- or long-sighted before they develop a cataract.
