What is Presbyopia?
As we age, the eye’s natural lens becomes too stiff to focus up close. With our hardening lens, 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 treat presbyopia, including SMILE, LASIK, PRK, Refractive Lens Exchange (RLE) and Intraocular Collamer Lens (ICL) with monovision, and multifocal intraocular lenses.
Monovision
Monovision is a treatment option where one eye is corrected for distance while the non-dominant eye is left undercorrected to see up close. The brain integrates the visual information from both eyes and adjusts to have each eye focus at a different distance. This adjustment period can happen immediately or take up to a few weeks. Monovision can be achieved with all of our High Definition Vision® solutions.
Extended Range of Vision IOL
The TECNIS® Symfony Extended Range of Vision IOL is the first and only presbyopia-correcting extended range of vision IOL. It is designed to provide a full range of high-quality vision for far, intermediate, and near distances. This provides a seamless transition between distance and near vision. It also reduces the chance of halos and glare at night.
