LASIK is a surgery that is used to correct refractive errors, such as far-sightedness, near-sightedness, and astigmatism, so that people can be less dependent on glasses and contact lenses to get ...
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 ...
LASIK surgery is performed by an ophthalmologist who uses a femtosecond laser or a microkeratome to create a corneal flap to expose the corneal stroma and then an excimer laser to reshape the corneal stroma in order to improve visual acuity. [2] [3] LASIK is very similar to another surgical corrective procedure, photorefractive keratectomy (PRK ...
One conspicuous difference between SMILE and LASIK is the size and shape of the corneal incision. In LASIK, the surgeon performs a 270-degree, 20 mm long incision, while in SMILE the so-called "side cap cut", which is the incision through which the surgeon extracts the lenticule, is usually about 4 mm long.

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.
With PRK, the corneal epithelium is removed and discarded, allowing the cells to regenerate after the surgery. The procedure is distinct from LASIK (laser-assisted in-situ keratomileusis), a form of laser eye surgery where a permanent flap is created in the deeper layers of the cornea. However, PRK takes longer to heal and can, initially, cause ...
