With Custom Monovision, we aim for distance vision in the dominant eye. We aim for reading vision in the non-dominant eye by making it nearsighted. Having one eye set for distance and one eye set for near increases the number of things that you can do without glasses. This approach after cataract surgery or refractive lens exchange works best in patients who have previously had success wearing contact lenses for monovision.
The disadvantage with monovision is that both eyes may no longer work together for distance or near vision. Some patients, realizing the advantage of increased freedom from glasses and contacts, tolerate this disparity extremely well. Other patients are unable to tolerate the imbalance between the two eyes. The goal with Custom Monovision is to see well enough to pass a driver’s test and read a newspaper without glasses.
