Wavefront-guided LASIK is a variation of LASIK surgery in which, rather than applying a simple correction of only long/short-sightedness and astigmatism (only lower order aberrations as in traditional LASIK), an ophthalmologist applies a spatially varying correction, guiding the computer-controlled excimer laser with measurements from a ...
The review stated that no trials have been conducted comparing the two procedures on people with high myopia. [18] A 2017 systematic review found uncertainty in visual acuity, but found that in one study, those receiving PRK were less likely to achieve a refractive error, and were less likely to have an over-correction than compared to LASIK.

Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses.This can include various methods of surgical remodeling of the cornea (keratomileusis), lens implantation or lens replacement.
A 2012 review could not find strong evidence for any single cause, although many theories have been discredited. [35] Twin studies indicate that at least some genetic factors are involved. [ 27 ] [ 36 ] [ 37 ] Myopia has been increasing rapidly throughout the developed world, suggesting environmental factors are involved.
A dacryocystorhinostomy or dacryocystorhinotomy is a procedure to restore the flow of tears into the nose from the lacrimal sac when the nasolacrimal duct does not function. [ 33 ] [ 35 ] Canaliculodacryocystostomy is a surgical correction for a congenitally blocked tear duct in which the closed segment is excised and the open end is joined to ...
Laser Blended Vision does not carry specific increased serious risks relative to the standard LASIK laser eye surgery itself. As with all laser eye procedures, patients must familiarize themselves with the risks and side effects of the treatment, which is best done in consultation with an expert laser eye surgeon who performs the Laser Blended ...
The method of extraction was via a LASIK-type flap in ReLEx FLEx, but in SMILE a flapless technique makes a small tunnel incision in the corneal periphery, that does not (mostly) destroy Bowman's layer. [4] One conspicuous difference between SMILE and LASIK is the size and shape of the corneal incision.
Gholam A. Peyman (born 1 January 1937) is an Iranian American ophthalmologist, retina surgeon, and inventor. He is best known for his invention of LASIK eye surgery, [2] a vision correction procedure designed to allow people to see clearly without glasses.
