The TECNIS Symfony IOL takes advantage of a new optical technology, different than the one used by current multifocal IOL’s, for offering an Extended Range of Vision.
Until now IOL correction for presbyopia was achieved through:
– IOLs with different designs (bifocals , near segment sector-shaped, trifocals…) that split the light in several focal areas.
– Accommodative IOLs that change their shape and dioptric power when the ciliary muscles contract.
Instead of several focus areas, the TECNIS Symfony IOL get one elongated focus area by implementing two technologies:
– Proprietary diffractive optic design that extends the length of focus.
– Achromatic technology that corrects chromatic aberration.
