Fluidvision accommodating iol power vision
Various conditions of the eye, including cataracts and Presbyopia, result in the loss of accommodative ability. The Fluid Vision accommodating IOL, which is made by Power Vision, Inc., utilizes natural forces within the eye to displace fluid in the lens through internal channels, changing its shape and increasing or decreasing the power of the lens.The pilot study included 20 patients who were candidates for cataract surgery and underwent unilateral implantation of the Fluid Vision lens.Discussing new technology involves more than just the next iteration of a technology or a minor (but still useful) enhancement.Last month, Eye World asked experts around the world for their opinions on extended depth and range of focus lenses.In Europe, the next-generation Synchrony Vu accommodating IOL features a central blended aspheric zone designed to extend the depth of focus. Alio is really looking forward to having a customized Q value for lenses as occurs in the My Lentis (Oculentis) study, where surgeons manipulate the asphericity in normal and post-laser vision correction surgery.Purely increased depth of focus lenses are under investigation, but the problems with centration and quality of vision are still to be solved, Dr. Secondary multifocal IOL implantation and toric intraocular lenses are indeed a tremendous opportunity for patients now in Europe. Negative dysphotopsia lenses (like the lens designed by Samuel Masket, MD) are under evaluation in Europe.The Synchrony lens (Abbott Medical Optics, AMO, Abbott Park, Ill.) does actually accommodate.
In Europe, several trifocal lenses are doing pretty well, Dr.

The Harmoni lens (Clar Vista, Aliso Viejo, Calif.) not only boasts the lowest PCO rate of any currently available lens (80% less PCO in rabbit studies), but it will allow surgeons to swap out the optic in the case of a refractive surprise while the haptics remains in place in the capsular bag.
Cummings said, adding anecdotal evidence that these lenses are helping to grow a once-stagnant market. LISA (Carl Zeiss Meditec) and the Fine Vision (Phys IOL, Liege, Belgium).
Theyre almost like regular monofocals with an absolute defocus curve, good distance, a minimal gap for intermediate, and good near, he said.
