Odd announcement

**chip anderson** · 09-10-2009, 09:32 AM

I just saw a notice in Review of Optometry on line stating that American Medical Optics was about to aquire Visiogen. The "article" went on to say that the "Synchrony" was designed for cataract patients with or without presbyopia ? Anyone ever seen a post-op catract patient with accomodation? I haven't.

I think they mean for younger patients....like traumatic cataracts, etc...

Why are you reading Review of OPTOMETRY anyways??? :bbg:

...and now it's Abbott Medical Optics.

Last I heard even infant aphakic patients had no, zero, nada accomodation. Traumatic, or otherwise an aphakic eye has no accomodation at any age.

If so, then why the accommodative exercises post op for patients with accommodative IOL's?

I suppose in theory one could flex a soft enough plastic lens in the bag and call it "accomodation".. However in truth I suspect such "exercises" are just getting the patient used to the vision through an aspheric implant. Much as one would try to pursuade a patient in a soft aspheric bifocal contact that could actually read J print but was complaining about the quality, that it would "improve with time."

Not true, the cystalens IOL works by actually changing its position anterior/posterior to achieve some level of "accommodation." For that reason, when we are counselling these patients post-op we often recommend therapy similar to orthoptic therapy for accommodative insufficiency in children and young adults. This gets these patients back into the swing of things...actually using their ciliary muscles for the first time in 20+ years... Thats the theory anyways...
