Monovision is a technique that can be used with LASIK where one eye is corrected to see distant objects and the other eye is corrected to see near objects. It dramatically reduces a presbyopic person's dependence on reading glasses. However, it usually decreases one's depth perception and peripheral vision. Monovision is considered by many to be a viable compromise to correct distance and near vision for the person with presbyopia. Dr. Kelly usually has patients considering monovision undergo a trial with contact lenses before the procedure.
