Anyone hear of the Juvene IOL? It's a fluid-filled IOL that can change power when the ciliary body contracts and relaxes. I wonder how effective this would be if weakening of the ciliary muscles is one of the causes of presbyopia. Here's the title of the article: GRAIL Study Supports Modular, Shape-Changing IOL Thoughts?
I have to admit that I am in the skeptical crowd on this one. I believe it is now in the trial stage, and depending on where you are, you may be able to get into the trial. Given the invasive nature of an IOL, and the difficulty of doing an exchange if it does not turn out well, I would not be first in line to do a trial…
This is a great point! I read that disruption to the bag that holds the lens in the eye is one of the highest risk factors of RD…I’d pass on that basis alone.
True but i believe that’s because the bag essentially collapses after traditional cataract surgery (since today’s IOLs are much smaller than the bag). This change in volume can cause a pressure change or something. Also the phaco process itself (which is used in all cataract surgery today) is somewhat traumatic. Juvenne still requires phaco of course but the bag-filling nature of the implant theoretically would reduce the risk of detachment, not increase it.
.
Juvenne has 3 parts… the bag-filling holder, a static base lens which I assume is targetted for plano distance, and the dynamic fluid filled optic that gives you the accommodation. I do not know, but I suspect that worst case, if the fluid filled optic fails you probably just lose accommodation but still nave a functional monofocal?
