Your lens implant will determine whether you will need glasses or contact lenses after cataract surgery, and what your prescription will be if you do.Intraocular lenses have been around since the mid-1960s, but it wasn’t until 1981 that the FDA approved them for use.Intraocular lenses are the solution to these problems.
Unfortunately you must wear eyeglasses or contact lenses in order to be able to read, use a computer, or view objects in the middle distance, especially if you had been experiencing presbyopia (loss of clear close-up vision) before the cataract surgery.
Multifocal lenses, also known as accommodating lenses, are the newest type of IOL.
There is a debate, however, about how long this contrast sensitivity can last in older patients, since the ganglion cells of the retina play a major role in determining contrast sensitivity, and we gradually lose those cells as we age.
There are different options available if you and your doctor choose to use aspheric IOLs.
In small case studies this IOL has demonstrated the ability to restore focus at a range of 1.00 to 5.00 diopters, which is about twice that of a control group.
Just like regular contact lenses, toric IOLs are meant to correct astigmatism.
Staar Surgical IOL was the first toric IOL available in the United States.
The Staar toric IOL comes in a full range of distance vision powers, and in two versions: one that corrects up to 2.00 diopters, and another that corrects up to 3.50 diopters of astigmatism.
There are many potential causes for cataracts, including diabetes, but the most common cause is age.
The lens’s ability to be folded enables surgeons to make a small “no stitch” incision during cataract eye surgery, and results in a quicker recovery time.
