Overall, PRK is considered to be safer and more effective in the long term because it doesn't leave a flap in your cornea. The flap left behind by LASIK can be subject to greater damage or complications if your eye is injured..
Consequently, is PRK better than Lasik?
PRK is very safe and stable procedure; the surgery is FDA approved, and is a great option for qualified patients. The outcome of the surgery is very similar to Lasik, although due to a difference in how the procedure is preformed, PRK is better suited for certain types of patients.
Similarly, is PRK permanent? PRK remains a common option for laser eye surgery. PRK and LASIK both permanently reshape the cornea to improve vision by using a laser (an excimer laser to be exact) to remove part of the tissue underneath the corneal epithelium.
how long does PRK last?
The results of your PRK do not diminish over time. Once your eyes have stabilized, usually in three to six months, your vision correction is permanent. This doesn't mean, however, that your vision won't change.
What is the success rate of PRK surgery?
The Success Rates of PRK Surgery PRK is highly successful at treating refractive errors, which you may know better as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. Studies of PRK patients have found that 70 percent achieve 20/20 vision or better; 92 percent will achieve 20/40 vision or better.
