Crystalens
— Far, Near, and In-Between
The
Crystalens implant (made by Eyeonics, Inc.) can give semi-near reading
vision, arm's length, and distance vision without glasses because this
implant actually adjusts its position within the eye as the eye looks
from far to near subjects, much like an 'auto focus' mechanism on a
camera. The Crystalens is powered by the same ciliary body muscles that
move and focus the eye's own natural lens. Its unique, hinged shape
allows for this lens movement and gives a seamless transition from far
to arm's length to near vision. Most people with the Crystalens have
clear far vision (driving, television) and intermediate vision (arm's
length, desktop computer screen) without any glasses. Most people can
also read newsprint without glasses when the two eyes are targeted for
post operative assymetry. One eye is targeted for distance
while
the other eye is targeted slightly more for near vision. Some people do
need glasses for fine print, especially in dim light. Of the three
lenses, the Crystalens is most likely to provide the best vision for
driving at night.
