Premium IOLs

implantFor New Jersey patients who undergo cataract surgery, the surgeons of Campus Eye Group offer the latest premium intraocular lens (IOLs) implants to replace the eye’s damaged natural lens. Traditional IOLs are “monovision,” meaning they allow focused vision at only one distance (near or far). However, the premium IOLs provided by the doctors at Campus Eye Group – such as Crystalens, ReSTOR, ReZoom and Toric – are able to correct various vision and errors, including myopia, hyperopia, presbyopia and astigmatism, allowing patients to see clearly at multiple distances. Due to their ability to correct presbyopia, premium IOLs are also referred to as presbyopia-correcting IOLs.

Multifocal IOLs

3d eye presbyopiaThere are two main types of premium IOLs: multifocal and accommodating. Multifocal IOLs have zones that focus at different distances, similar to progressive eyeglasses. They work because the brain learns which zone to look through to focus at whatever distance the eye needs to see – whether far, middle or near. The advantage of multifocal IOLs is that they allow for clear vision at multiple distances; the disadvantage is that they provide less contrast sensitivity (the ability to distinguish objects from their background) than monovision lenses, which may make it more difficult to see while driving at night. Various brands of multifocal lenses are available, including ReSTOR, ReZoom and Toric.

  • restorReSTOR is manufactured by Alcon and comes in two versions. The original version, approved by the FDA in 2005, permits the eye to focus on near, middle and distant objects by changing the way light enters the eye depending on the lens’ different focusing zones. A newer version of ReSTOR was approved by the FDA in 2008. It differs from the previous version in that it has a near power that allows for greater clarity at intermediate distances.
  • rezoomReZoom is manufactured by Abbott Medical Optics and was approved by the FDA in 2005. Like ReSTOR, it uses different zones (arranged in concentric circles) to focus the light entering the eye for clear vision at different distances.

  • toricToric is manufactured by Alcon and was approved by the FDA in 2005. Like ReSTOR and ReZoom, it is a multifocal lens that allows focused vision at near, distant and intermediate ranges. However, it has the added feature of correcting astigmatism for enhanced image quality. A new, aspheric version of Toric was approved in 2009. Alcon reports that patients receiving the new version are less likely to need a second surgery to realign the lens.

Accommodating IOLs

In contrast to multifocal lenses, accommodating lenses have only one focusing zone. However, they allow the eye to focus at different distances by shifting their position in the eye (thus “accommodating” the eye).

  • crystalensCrystalens is the only accommodating lens approved by the FDA (in 2003) for use in the United States. Its advantage is that it may produce fewer night vision problems – such as glare and halos – than multifocal lenses. However, it may provide a smaller range of focus (near to far) than multifocal lenses, thus necessitating the use of reading glasses.
