What is the difference between PRK eye surgery and LASIK?
PRK and LASIK are very similar. LASIK has a tiny blade that cuts the cornea. On the other hand, PRK doesn't do this. PRK uses a laser to reshape the cornea without cutting it.
What kinds of vision problems can be corrected by LASIK surgery and by PRK surgery?

What are facts about PRK laser?
PRK Laser Eye Surgery is a type of refractive surgery. PRK reshapes the cornea using an excimer laser. Unline LASIK, in PRK, the cornea's entire outer layer is removed and no flap is created. However, recovery from PRK is a little longer than recovery from LASIK.
How is PRK different than Lasik eye surgery?
There are a few differences between PRK and Lasik eye surgery. PRK was the first laser surgery used to correct vision. The main difference between the two is that it usually takes longer to recover from PRK surgery. With Lasik surgery a small hinged flap is made on the cornea, and with PRK the entire surface of the cornea is removed and therefore takes longer to recover.
What is the difference between Lasik and PRK?
LASIK and PRK are both laser procedures that correct nearsightedness, farsightedness, astigmatism and presbyopia. The main difference between the two is the following: LASIK uses a microtome knife or laser to create a flap followed by use of an Eximer laser to ablate the corneal tissues. PRK, on the other hand, uses a sterile brush or laser to scrape away the surface corneal epithelial cells, followed by use an Excimer laser to ablate and reshape the corneal tissue. Although PRK takes longer to heal and produces more discomfort than LASIK, it is an ideal surgery for patients with thin corneas and large pupils.

Because the cell layer is not permanently removed, patients have a faster recovery time and experience far less discomfort than with PRK
