"The annular peripheral haptics are the reservoirs for the fluid, and as the ciliary body and zonular apparatus contract and expand, that fluid in the peripheral annular haptics is forced radially through a channel into the center of the lens, causing it to increase its anterior posterior curvature," he said. "The lens was designed with the intent of harnessing Mother Nature's natural accommodative forces from the ciliary body expressed through the zonules and capsule to an artificial lens that would have shape changes that are similar and replicate our natural accommodative process," Dr. This, he noted, is in contrast to the Nu Lens (Nu Lens Ltd., Israel), which uses a reverse accommodative process, although it does appear to work. Nichamin views the way the fluid moves here as remarkable.Despite the difficulties in measuring accommodation, accommodative IOLs represent the future in the attempt to successfully “cure” presbyopia.
After receiving the CE mark, the company hopes to start FDA trials. "The base unit is put in on top of the bag and then a second optic is put in with the haptics that fixate in the sulcus," he said.

D., medical director, Laurel Eye Clinic, Brookville, Pa. Eye World had a heart- to-heart with practitioners already versed in the lenses to find out the intimate details of what gives these lenses their unique personalities.Institute of Vision and Optics (IVO), University of Crete, Medical School, Heraklion, 71003 Crete, Greece Received 7 March 2011; Revised 5 July 2011; Accepted 12 July 2011Academic Editor: Rupert M. In the attempt to manage presbyopia, different intraocular lens designs have been proposed such as monofocal IOLs with monovision or multifocal IOLs.
