N.M.
I had Lasik done with great results. When it came to my husband's turn, he was only able to get Lasik done on one eye and the other eye needed PRK instead. (Long story, but anyway...) Here is his experience:
His Lasik eye healed and felt better quickly. His PRK eye had a longer recovery and hurt like crazy. And for months he complained about not being able to see clearly, which is important to his job. But it turned out that the PRK eye ended up with sharper vision than the Lasik eye, and now he figures it would have been better for him to just have had both done with PRK, though he did not like the recovery period at all. It's been nearly a year now and his eyesight has finally adjusted--the PRK eye still sees better than the Lasik eye, but combined, they see well.
