PRK results in improved BCVA about twice as often as it causes loss. Decentration is becoming less and less of a problem with more modern lasers using sophisticated eye centering and tracking methods. Comparison to LASIK. A systematic review that compared PRK and LASIK concluded that LASIK has shorter recovery time and less pain.
PRK - Photorefractive Keratectomy - A Lasik Alternative PRK eye surgery provides an excellent alternative treatment option for patients that have myopic, hyperopic, and astigmatic visual errors. PRK and LASIK are similar in many ways, as they are both advanced laser vision correction treatments. However, they do differ in some important ways. PRK - LASIK Alternative | San Antonio Eye Center PRK (photorefractive keratectomy) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. PRK was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure. Today, those with myopia, hyperopia and/or astigmatism who are ineligible for LASIK may be good PRK candidates.… UVA LASIK UVA LASIK offers laser vision correction procedures, including LASIK and PRK.

It is an alternative to LASIK, most often recommended if a patient’s corneas are too thin to make LASIK a safe option for them. PRK was actually the first type of laser vision surgery and is the predecessor from which LASIK was created. PRK vs. LASIK: How is PRK different from LASIK?

PRK vs LASIK - Comparing PRK to LASIK - Which procedure is
Nov 16, 2018 · PRK and LASIK each use different methods to help correct your vision by reshaping cornea tissue. With PRK, your eye surgeon takes away the top layer of the cornea, known as the epithelium. PRK (photorefractive keratectomy) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. PRK was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure. Though PRK recovery takes a bit The PRK & LASIK Procedure. The big difference between LASIK and PRK laser eye surgery is how the eye is prepared for surgery. With LASIK, the surgeon creates a hinged flap by making an incision in the cornea. This flap gives the surgeon access to the part of the cornea that needs to be reshaped. PRK is the identical laser vision correction treatment performed directly on the corneal surface (rather than beneath a flap as with LASIK). Both LASIK and PRK treatments provide excellent visual outcomes and freedom from glasses for distance vision for nearly all patients. PRK and LASIK generally provide equivalent visual outcomes. While LASIK’s advantages are the result of the LASIK flap, PRK’s advantages are actually the result of not having a flap. In spite of the longer, more challenging visual recovery after PRK, for certain patients, PRK is the patient’s preference, and in other cases, PRK is the better procedure from a medical perspective to treat their vision. During PRK, an eye surgeon uses a cool pulsing beam of ultraviolet light on the surface of your cornea. LASIK, another type of laser surgery, works underneath your cornea. LASIK, another type of LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most people, LASIK provides a long-lasting alternative to eyeglasses or contact lenses. LASIK is most similar to another surgical corrective procedure, photorefractive keratectomy (PRK), and LASEK.
