Monovision is the process of one eye being optimised for near focus and the other eye for distance. For those patients where Presbyopia has started to affect the eyes, this is a good treatment option.
Presbyopia refers to the reduction in range of focus from far to near that occurs naturally with time from the mid forties. The loss of uncorrected reading vision caused by Presbyopia can be partially overcome by choosing to leave one eye slightly shortsighted for reading, whilst fully correcting the fellow eye for distance.
A contact lens trial is usually recommended prior to proceeding with monovision laser to assess suitability for this option.
