Can Excimer Laser correct every eye to get 20/20 vision?
No. If the eye has only 20/100 as the best corrected vision with glasses or contact lenses, the chances are that is all that the eye will see after treatment. Such low vision is due to so many causes that cannot be treated with Excimer laser. If the eye is very shortsighted and the vision is 20/50 with glasses Excimer laser treatment may “improve” the vision to 20/20 in the same way a contact lens will for that eye.
