Omnivision
For patients who use bi-focal lenses to correct both near- and farsightedness, traditional laser vision correction surgery poses a problem because it is designed to treat just one of the two conditions. That is where Omnivision, which means vision at all distances, comes in.
In this procedure, one eye is corrected to give optimal vision at distances and the second eye is intentionally corrected to have a small amount of nearsightedness. To ensure the patient will not be bothered by seeing differently in each eye, a trial of Omnivision using normal corrective lenses (i.e., glasses or contact lenses) is done prior to the permanent surgical procedure.
