One more time. - (I don't have the time or training to read through and
evaluate a number of technical articles.) - My ophthalmologist has
suggested the Crystalens as providing some degree of accommodation for
my presbyoptic condition. (I'm considering cataract surgery because of
difficulty in seeing under any degree of background glare due to
crystallization in the lens(?) and also, highly variable eyesight.  I
also seem to be unable to read most traffic signs clearly enough to
respond safely.)  Note that I don't expect to be able to read small
print without glasses (reading glasses are OK with me), but I would like
to be able to see both distant and mid-distance objects (e.g., 6 - 25
feet) clearly. I sense that some patients and practitioners don't think
the benefits offered by the Crystalens are worth the extra cost. -
However, I do note that they are FDA approved. According to one report:

    "In the  FDA clinical trials it was found that a vast majority, but
not all, patients implanted with a Crystalens accommodating IOL achieved
a measurable improvement in accommodation. It was also indicated that
the Crystalens provided vision quality equal to or better than a
conventional IOL..."

As understood, it takes a substantial period of time, e.g., six to eight
months, for many patients to accomplish adaptation to the Crystalens
lenses.  Does anyone have information (readily available and
understandable to a layman) concerning typical results for patients WHO
HAVE GONE THROUGH SUCH AN EXTENDED ADAPTATION PERIOD? Also, what
negative factors should I be aware of concerning such adaptive lenses?
For example, do they limit or restrict vision at night? (I'm into
amateur astronomy, in which the pupils may expand to 6-7 mm during night
viewing.)

Thanks,
Jim
