Monovision LASIK


Monovision is a unique LASIK procedure that corrects the dominant eye for distance vision, while correcting the other eye for near vision. The need for bifocals or reading glasses is reduced or eliminated.

For patients with perfect distant vision without glasses or contacts, only the non-dominant eye needs to be corrected.

Typically, the brain easily adapts and compensates for the two different levels of correction. When the patient looks into the distance, the distance corrected eye is at work. And when the patient looks down to read, the eye corrected for near vision does the work.

Before undergoing surgery, we recommend patients do a monovision test trial using contact lenses to determine if any problems occur.

The Monovision procedure can be performed as an individual LASIK (iLASIK), Femto-LASIK or wavefront-guided LASIK treatment.

(1) Femto-LASIK           (2) Femto-LASIK

(1) A microkeratome or femtosecond laser (as shown here) is used to create the corneal flap. (2) Then, the excimer laser reshapes the cornea so that it will focus light more efficiently. The corneal flap is put back in place after the laser correction.


Monovision may interfere with depth perception and can also cause reduced peripheral focus in certain circumstances, for instance when glancing quickly at rear-view mirrors in the car.
