Your eye has a clear lens through which light passes, allowing you to see. When the lens loses its transparency, the cloudy tissue that develops is known as a cataract.
Cataracts cause progressive, painless loss of vision. The lens clouds naturally as we age, so people over the age of 65 usually see a gradual reduction of vision. No one is exactly sure what causes cataracts. In younger people they can result from an injury, certain medications, or illnesses such as diabetes. Prolonged exposure to ultraviolet light may also play a role in the formation of cataracts. Studies have also shown that people who smoke cigarettes have a higher risk of developing cataracts than non-smokers.
Although cataracts usually develop without apparent pain, some indications that a cataract may be forming are:
- Blurred or hazy vision
- Double vision
- Poor vision in bright light
- Seeing halos around lights
- Poor vision at night
- Yellowish tinged vision
- Frequent changes in eyeglasses or contact lens prescription
Premium Lens Implants
If you have cloudy vision due to cataracts, intraocular lenses (IOLs) are an effective way to restore your vision. While standard IOLs correct your eyesight at only one distance, premium IOLs are designed to improve near and long-distance vision. This means patients, who choose a standard IOL, might still require glasses for reading or driving. Individuals that are interested in a more overall improvement can get a Premium IOL that will allow them to see clearly at near, mid, and long ranges. A Premium IOL may eliminate the need for visual aids altogether.
There are several different IOLs available to help each patient achieve the best possible results from his/her cataract surgery.
In the past, cataract lenses were only able to correct distance vision, often leaving patients with the need for reading glasses. Multifocal IOLs offer patients freedom from glasses after cataract surgery by improving vision at all distances and at any time of day. These lenses can quickly change focus to accommodate your vision needs. Up to 80 percent of patients do not need to rely on glasses with multifocal IOLs.
Accommodative IOLs offer a full range of restored vision for cataract patients. Many people experience a loss of near vision with age and often need to rely on glasses after cataract surgery. Accommodative IOLs such as Crystalens® replace the natural eye’s natural lens and mimics its accommodation capabilities, allowing you to see clearly across a wide range of distances.
Toric IOLs are specifically designed for patients with astigmatism. In the past, patients with astigmatism would need eyeglasses or contact lenses even after cataract surgery in order to correct the problem. Toric IOLs such as AcrySof Toric corrects cataracts and astigmatism with just one lens, providing a more convenient and affordable solution to your vision needs.
