Crystalens accomodating

Ever since their conception, multifocal intraocular lenses (IOLs) have been measured against their predecessor, monofocal lenses.

Petersburg, Fla.), which is in Phase III of the FDA clinical trials, is Dr. “With this lens I get on average about 2.0 diopters of accommodation, with some patients getting up to 3.

It’s got a large optic, 5.75mm, so I don’t have issues with glare with the lens and I find that of the two accommodating lenses, [it is the easier one] to put in. Dougherty, principal investigator in the FDA trials, said that there are no issues with anterior vaulting, unlike the Crystalens since the Tetraflex is a 5 degrees anteriorly vaulted accommodating lens that works by contraction of the ciliary muscles to increase vitreous pressure. Dougherty said he likes about the lens is that because there’s a known distance from the optic to the focal point as it does not have hinges, his lens calculations are identical to what he would get with a standard monofocal lens.

The Crystalens AO IOL (Intraocular lens) is the first lens of its kind to mimic the contraction of eye muscles to accommodate and focus at near, immediate and far distances.

The main difference between the Crystalens AO and other multifocal lenses is that the Crystalens uses technology to accommodate and allow clear vision at all distances, instead of just multiple distances with multifocal lenses, which are divided into zones of vision.

Some of them don’t wear glasses but I don’t want to promise that. to insert the Crystalens as well as the medical director involved in attaining Food & Drug Administration (FDA) approval of the lens, explained: “I don’t think there’s any downside in terms of risk or decreased quality of vision or anything compared to us using the very best monofocal IOL.

“The advantage to the accommodating lens and the reason why we wind up doing mostly Crystalens (eyeonics, Aliso Viejo, Calif.) [in my practice] is that I don’t see a downside to the Crystalens compared to a normal IOL.” Dr. And you may get a good percentage of people who will get a reduced dependence upon glasses.” Although multifocals offer a good chance of patients not needing to wear glasses, Dr.

Eye World takes a look at the pros and cons of the lenses. D., Nashville, agreed, “The Re STOR is definitely the best near vision lens on the planet.” However, Dr.

A big advantage of multifocal lenses, said Stephen G. D., Houston, is that the Re STOR lens (Alcon, Fort Worth, Texas) has the best near vision of any of the lenses. Slade said, “The disadvantage [of multifocal lenses] is that some patients, not very many, but some have problems with the quality of vision, either glare or halos or they describe waxy vision or things like that.” Paul J. D., clinical instructor of ophthalmology, Jules Stein Eye Institute, University of California at Los Angeles, said of the two multifocals, his preferred lens is the Re STOR Aspheric because it tends to be the most effective at eliminating the need for glasses for distance and near.
