Clinical research of accommodating intraocular lens
The Crystalens® is an FDA-approved intraocular lens for the visual correction of adults with cataracts (clouding of the eye's natural lens secondary to age) with or without presbyopia, or lenses that have aged or become more rigid. Like the natural lens, it uses the eye muscle to flex and accommodate in order to focus on objects in the environment at all distances.The crystalens dynamically adjusts to your visual needs.The Crystalens represents the state-of-the-art in implantable lens design and is the result of over 50 years evolution in the treatment of cataracts.The medical procedure to implant the crystalens is the same safe, proven cataract surgery performed annually on over 7 million eyes globally.Intraocular lenses are used during cataract surgery to replace the damaged lens of the eye with an implant that clears up and corrects vision, oftentimes leaving patients with little to no dependence on glasses.Up until now, patients with astigmatism did not have the same opportunities that other cataract patients have had in correcting their condition with the types of IOL lenses that were available.A wide range of replacement lenses are available to cataract patients, each offering different advantages for post-surgery vision.The most effective lens to use depends on the patient’s individual preferences and goals for their vision.
In the past, cataract surgery only involved monofocal lenses, which could only focus on objects near or far, but could not adjust to accommodate varying distances.
The Crystalens IOL is made with flexible silicone that has hinges on each side allowing it to move with the eye muscle, flexing and accommodating seamlessly so you can focus on the objects around you at any distance.
In other words, it dynamically adjusts to your visual needs.
Accommodation is the ability to shift focus between nearby and distant objects, providing sharper vision at multiple distances in order to minimize the use of glasses.
Other IOLs are unable to accommodate and those patients may require additional vision correction with glasses or contact lenses.
