PRK surgery takes more recuperation time than laser eye surgery. Primary difference between PRK surgery and Lasik eye surgery is that in laser surgery a lean hinged flutter created to access the area to be treated.  In PRK surgery, the complete epithelial layer get taken out.  

Lasek: Laser-assisted Subepithelial Keratomileusis in this surgery surgeon keeps the outer layer of cornea and treat the cornea beneath. Then surgeon replaces the epithelium to shield the eye while it cures. Patients are given special contact lenses to wear during healing period.

How effective is refractive and laser eye surgery
However, Laser eye surgery is effective but there are few side effects of the surgery.
