Whats The Diffrence?

Both Lasik and PRK are procedures to correct vision. Hopefully the end result being 20/20 eye sight. Laser vision correction performed under a flap (LASIK) offers numerous advantages over laser vision correction performed on the cornea’s surface (PRK). Notably, there is a more rapid improvement in the vision and decreased discomfort with LASIK since epithelial cells have been preserved and do not need to grow back. This is without doubt the reason that LASIK has become the corrective surgery of choice for both doctors and patients. However, in some patients, PRK is a safer alternative that may promise better outcomes. Patients who might benefit from PRK include those in whom the cornea might be too thin for LASIK, or in some patients with corneal irregularities or scars.
I personally had the PRK because it was free for me. The outcome is excelent. It has been over two years now and I can see great. My father had the Lasik done about five years ago in canada and he can see just fine as well. He is an older man and still needs to wear reading glasses from time to time.
