The good news is that PRK and LASIK surgery results are considered a permanent solution for vision loss, and most people find that their improved eyesight lasts for a lifetime.
How long does PRK last for?
What are the advantages of PRK? PRK can accurately correct nearsightedness. Approximately 90% of PRK patients have 20/20 vision without glasses or contact lenses one year after the surgery.
Is PRK surgery permanent?
PRK (photorefractive keratectomy) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. Though PRK recovery takes a bit longer than recovery from LASIK eye surgery, PRK is still commonly performed and offers advantages over LASIK for some patients.
Is Lasik permanent?
In most cases the improved vision LASIK surgery provides is permanent. But in a limited number of cases — usually due to changes that can occur in the lens inside the eye, with or without LASIK surgery — some nearsightedness, farsightedness and/or astigmatism can return over time, causing blurry vision.
Which is better PRK or Lasik?
The difference is that #LASIK reshapes your cornea underneath a flap (think of the flap as being like a trap door on your cornea) whereas #PRK reshapes your eye on the surface. LASIK offers the advantage of quicker healing. Most patients with LASIK have excellent vision the day after surgery.
