Re: Lasik eye surgery
PRK vs LASIK.
Lasik is where a "flap" is cut on the cornea, and flipped over. Then laser correction occurs, and the flap is returned to its original position.
PRK is where a thin layer of the cornea is "scraped" away. Laser correction occurs, and then the cornea must heal on its own.
PRK is used in some cases where the cornea is not thick enough to allow Lasik. It is typically more painful, and takes longer to heal.
Im not a doctor, but researched these options when I had my Lasik done. I hope this info is accurate, even though it is very simplified.
