Treating presbyopia to reduce or eliminate the need for glasses or contacts, requires leaving one eye untouched or refocused for long distance vision, and the other eye treated for near distance (reading vision) using Lasik.
It may seem difficult to get used to at first, but about six to eight weeks after the monovision procedure your brain is able to adjust to the different focusing ability of your eyes. A preoperative trial with contact lenses is a useful test to see if a patient will adapt to the intended refractive outcome.
Monovision can affect depth perception slightly. It is not recommended for people such as pilots, taxi drivers or anyone with a heavy vehicle license such as truck or bus drivers.
