Conventional spherical IOLs are monofocal lenses, meaning they are designed to provide clear vision at a single focal point (usually far away for good driving vision, for example).

Tecnis is the first intraocular lens designed specifically to improve the functional vision of older drivers who undergo cataract surgery.

Functional vision is the ability to see objects clearly under varying levels of light and in conditions such as rain, snow, fog and at night.

In other words, the eye's natural lens is aspheric ("not spherical"). A spherical intraocular lens can induce minor optical imperfections called higher-order aberrations (HOAs), which can affect quality of vision, particularly in low-light conditions such as driving at night.

Premium aspheric IOLs, on the other hand, match more closely the shape and optical quality of the eye's natural lens, and thereby can provide sharper vision — especially in low light conditions and for people with large pupils.
