LASIK involves cutting a small flap in the exterior of your cornea with a laser, then reshaping the corneal stroma underneath. Afterwards, the flap is replaced so that it can heal.
LASIK often allows for faster recovery than other types of laser eye surgery. Patients typically achieve clear vision in less than 24 hours and totally heal within 3 months.
PRK typically takes longer to recover from than LASIK. Most patients can expect clear vision in less than 5 days and total healing within 6 months.
