    No one has posted re Crystalens since March '06.
    Haven't new data surfaced? How does a patient
    choose intelligently between Crystalens and a simple
    monofocal IOL? How many years can one expect
    the "hinges" to last?

    The ophthalmologist says either IOL would work but
    refuses to accept the responsibility of choosing.
    If this topic has been exhausted, I'd greatly appreciate
    email containing perspectives supported by theory
    and/or experience.

    Thank you,
    Gordon

  2. We have a detailed article about the Crystalens accommodating
    intraocular lens (IOL) on our website at http://www.USAEyes.org Click
    on | Considerations | Which Surgery For You? | Crystalens |

    There has not been a tremendous amount of news since March '06. One
    study suggested the lens does not actually move as was theorized, but
    some accommodation does occur for some patients.

    Posterior Capsule Opacification (OCP) is supposed to be reduce with a
    slightly new design, but the physics of IOLs would indicate that a
    Crystalens is likely to do nothing to slow or stop OCP. The treatment
    for OCP is to use a laser to create a hole in the posterior capsule,
    however this may have an effect on the ability of the Crystalens to
    accommodate.

    There have been some difficulties with implantation and positioning,
    but nothing that is out of what one would consider the norm for a new
    technology.

    Keep in mind that the most accommodation you would get with Crystalens
    is about 1.50 diopters, and that would be if everything goes well.
    Take a look at the number on your reading glasses. If it is more than
    1.50, then you will still be needing reading glasses for close work,
    but possibly not as often with Crystalens.

    You should also take a close look at monovision correction. Go to our

    The Eye Care Forum at Med Help International contains some fascinating
    recent threads about the Crystalens, ReStor and ReZoom lenses. Based
    on my reading of this info, I'd definitely choose a monofocal aspheric
    IOL (such as the AMO Tecnis lens) over any of the above. An industry
    insider posted that the "best" aspheric for a particular person can be
    determined by means of wavefront and Q-scan testing, but I'm not sure
    who is doing this type of testing.
