Crystalens studies accommodating lens
Cataract surgery is the most commonly performed surgery in the United States, with well over 2 million Americans having the procedure every year.
Performed almost exclusively on an outpatient basis, cataract surgery is microsurgery, whereby the natural lens is removed and replaced with what is called an intraocular lens (IOL).
Crystalens is known as a 'Premium Intraocular Lens' and is particularly suited to those over the age of 40 who have presbyopia.
This condition lengthens eyesight as the focusing system becomes less flexible with age and near sight becomes more difficult.
This makes it less likely to produce side effects such as halos and glare.
However the Crystalens may not provide such a range of focus as a multifocal lens and therefore reading glasses may still be required.
As we age, these changes occurring to the natural crystalline lens can lead to the development of cataracts.
The Crystalens belongs to a select category of high tech intraocular lenses commonly called 'multifocual intraocular lenses'.This condition - for most, a natural consequence of aging - is called presbyopia.Some people begin experiencing the early effects of presbyopia (such as gradual loss of near vision) in their mid-40s.Also, there are other side effects associated with Crystalens, such as astigmatism, which can happen if the lens shifts position in the eye during the healing process.Like accommodating lenses, multifocal lenses are considered an optional, premium lens, cost more than standard monofocal lenses, and are usually not covered by vision insurance.
