One of the most common eye problems among seniors, the development of cataracts can cause vision problems and vision loss. A cataract is a painless clouding of the lens in the eye that causes blurry vision.
It progresses slowly as we age. Causes of cataracts include aging, diabetes, trauma, some medications, and excessive UV light exposure.
Your doctor can see a cataract while doing a routine eye exam. Surgery is curative as the cloudy lens is removed and replaced with an artificial one, called an IOL or intraocular lens. There are many types of Intraocular lens and will determine where the eye is in focus following surgery.
Implanted during cataract surgery, iStent inject® W can effectively lower IOP, one of the most important risk factors for glaucoma, and may reduce your reliance on glaucoma medication.
istent inject is one of the smallest medical implants known to be inserted in the human body and can lower the intraocular pressure, one of the most important risk factors in glaucoma.
Once implanted in the eye, iStent inject® W can help restore normal pressure in the eye. It’s designed to restore your eye’s natural ability to drain the fluid that causes the increased pressure inside your eye. This may allow your doctor to reduce or eliminate your glaucoma medications.
Cataract Symptom: Blurry Vision
The most common symptom of cataracts is seeing blurry images at any distance. People may describe their vision as foggy, cloudy, or filmy.
Cataract Symptom: Glare
Glare, or sensitivity to light, is another symptom of cataracts. It can be difficult for a person with cataracts to see in bright sunlight. Indoor lights may begin to seem too bright, or they may appear to have halos around them. Glare from oncoming headlights cause problems with driving at night.
Cataract Symptom: Double Vision
Diplopia, or double vision, when looking with one eye can be another symptom of cataracts.
Cataract Symptom: Color Changes
Cataracts also affect color vision. Some colors may appear faded, and things may acquire a yellowish or brownish tint.
Cataract Symptom: Second Sight
The cataract acts as a stronger lens, temporarily improving the ability to see things at a close distance. Unfortunately this decreases as the cataract progresses.
Cataract Symptom: New Prescription
People with cataracts often need frequent changes in their eyeglasses or contact lenses because their vision deteriorates over time.
Excessive use of alcohol
Trauma to the eyes
Extended use of corticosteroids
Prolonged radiation or sun exposure
Cataracts can be diagnosed with an eye exam. The eye exam contains a vision test and an examination of your eyes using a slit lamp microscope. The pupils are dilated to rule out other pathology.
Surgery to remove cataracts may be required if the related vision loss cannot be corrected with glasses or contact lenses. Cataract surgery involves removing the cloudy natural lens and replacing it with an artificial lens.
New developments in cataract surgery allow for IOL s that correct both near and distance vision, reducing or even eliminating the need for glasses after the operation. Conventional "monofocal" lenses only correct one focal distance, so people still need reading or driving glasses after surgery. So-called "toric" implants are available to correct astigmatism. Multifocal and or Extended depth of focus lens “ Symfony”correct distance and near and some also astigmatism, to reduce dependence on glasses.
