Fluidvision accommodating iol power vision validating software estimates
Keen intellects have been trying to tackle the problem of presbyopia at least since the time of Benjamin Franklin, who wrote in 1784 that he was “happy in the invention of double spectacles, which serving for distant objects as well as near ones, make my eyes as useful to me as ever they were.” Many people today remain just as happy with modern descendants of that same approach, but that hasn’t stopped researchers from continuing to explore innovative approaches, so that the billions of presbyopes in the world can each find a solution that suits them.
Here is a look at the latest emerging options to address this all-but-inevitable human need. The advent of stable lens platforms such as hybrid and scleral lenses is also good news for presbyopes with corneal astigmatism, adds Clark Chang, OD, director of the specialty contact lens service at the Cornea and Laser Eye Institute in Teaneck, NJ.
Intra-Ocular Lenses (IOLs) are a common necessity in complex ophthalmic operations, especially those involving glaucoma and cataracts. Alió, MD, Ph D, a consultant to Akkolens and Oculentis, multifocal lenses would soon give way to these IOLs. Jorge at the meeting of the European Society of Ophthalmology, “Once accommodative IOLs are developed adequately, multifocal IOLs will be unable to compete.
It has also had positive reviews in independent studies, including one study involving post-refractive patients, a group with surgically altered corneas for whom it is difficult to achieve target outcomes in cataract surgery.
The big test may come late in 2015, when Calhoun Vision (Pasadena, Calif.) seeks FDA approval of an IOL different than anything the FDA has seen before.
He noted that the IOL has 6.0mm optic and an overall diameter of 10mm.
hat do a Nobel laureate in chemistry and a professor of chemical engineering from the California Institute of Technology have to do with developing a new type of intraocular lens? That’s because the unique concept behind the Calhoun Light-Adjustable-Lens is to produce a chemical reaction that changes the shape of the lens which allows it to be adjusted once it is already in the eye.
In addition, the mean amplitude of accommodation as measured by defocus curves in those implanted monocularly was about 3.0D throughout follow-up, he said.
