As a person ages the lens of the eye becomes less flexible so that we have trouble focusing on near objects. In Monovision, or Autovision, the LASIK surgeon corrects the dominant eye for distance and slightly under-corrects the non-dominant eye so that it is focused at a near distance. Typically, the brain easily adapts and automatically makes the adjustment. When the patient looks in the distance, the distance eye is at work. When the patient looks down to read, the eye corrected for reading does the work.
PROCEDURES USED TO PERFORM MONOVISION CORRECTION FOR PRESBYOPIA INCLUDE:
Utilizing the clear lens extraction procedure maintains depth perception by implanting a bifocal lens, providing BOTH distance and near vision in each eye.
