The advantages and disadvantages are detailed as follows
Advantages: Safe TPRK is a direct operation on the corneal surface, with no incision and no scar, and the operation effect is better. In addition, the operation is simple and can be completed in one step, but it is safer. Athletes, soldiers, police, firefighters and other high-intensity occupations are most suitable for this operation.
Disadvantages: I feel a little uncomfortable, and I can't do it with a high degree. Tears, photophobia, foreign body sensation and other irritating symptoms are slightly severe, lasting 1-2 days, with poor comfort, and it takes about a week for vision to return to normal. For high myopia, the incidence of corneal haze is high, and myopia above 700 degrees is not suitable.
