How is PRK different from Lasik?

Since Lasik is so popular, may people want to know what the difference between these two procedures. The main difference is in how the surgeon can access to the stoma. With Lasik Eye Surgery, an eye surgeon will use a blade to cut a flap into the cornea. At this point, the surgeon gently folds this flap back and the laser is able to vaporize the stoma. With PRK, the surgeon does not create a flap in the cornea. Instead, the surgeon uses the laser to vaporize of portion of the surface cells along with the stoma.
