With time, the eye’s natural lens can become too stiff to focus up close. As a result, words and other nearby objects appear blurry. The clinical term for this loss of near vision is presbyopia.

There are a number of options to correct presbyopia (loss of reading vision) including SMILE, LASIK, PRK, PRESBYOND, Intraocular Collamer Lens, and multifocal intraocular lenses.


Monovision can be achieved with all of our High Definition Vision® solutions.

Monovision means one eye is fully corrected for distance while the non-dominant eye is left a little under corrected to see things up close. The brain integrates the visual information from both eyes and adjusts either immediately or within a few weeks to having each eye focus at a different distance. Most people tolerate this and can function most of the time without glasses.

Another way to give someone both distance and near vision is with a Refractive Lens Exchange (RLE) and a multifocal intraocular lens. Refractive Lens Exchange is the same procedure as modern cataract surgery, the most common surgical procedure in North America. 

The RLE procedure changes the focusing power of the eye by removing the eye’s natural lens and replacing it with an intraocular lens. This lens can provide good distance vision, good reading vision, or both.
