The CrystaLens accommodating intraocular lens (IOL) (www.eyeonics.com)
is very new, so you would probably need to rely on the FDA
information, which states that of all patients in the trials, 93.5% of
patients achieved Snellen 20/32 or better in distance, midrange, and
near vision.  Of those patients who were within .50 diopters of plano,
97.3% achieved Snellen 20/32 or better at near, midrange, and distance
vision.  Snellen 20/40 distance vision is required to drive in most
states.  The CrystaLens was considerably better at providing near and
distance vision, when compared to a standard non-accommodating IOL.

While all these stats do look impressive, there are some significant
limitations with the CrystaLens, and all seem to be dependant upon the
quality of the surgeon or the physiology of the individual's eye.
Placement of the haptics of the CrystaLens will determine if it
accommodates for near vision.  This placement is not easy to do, and
is literally around a blind corner.  If the individual's eye does not
have the ridge in the ciliary body needed for proper placement, the
lens will not accommodate.  This is not a surgery for a competent
surgeon, it is a surgery for an excellent surgeon.  You would want to
find someone who has significant practical experience with the
CrystaLens.
