As I am naturally short sighted (approx -3D in both eyes) I only had the right eye treated. I'm using mono vision, with an optional weak contact lens for my left eye for computer use. For reading, I don't need the lens.
After 3 days, my right eye is already better than with contact lenses.
The treatment was quicker and much less uncomfortable than I had expected. The staff were excellent, and so far, no complaints!
