I cannot wear contacts due to a pretty strong astigmatism, it make them extremely uncomfortable. I've heard that PRK is more proven and though it takes longer to heal it's a more permanent solution since with LASIK the layers never truly heal.
I am considering PRK (LASEK), but have not yet made my mind about it, as it is a procedure that is done less frequently than LASIK, so there might be issues that haven't been found yet.
