Cataracts Disease Information

Cataracts are a prevalent ocular affliction which happens when the lens of the eye becomes foggy, leading to fuzzy vision. Cataracts can affect people of all ages, but are more frequent in elderly people. Causes of cataracts can range from age, heredity, and certain medications. Surgery is an option for treating cataracts, whereby the hazy lens is removed and replaced with an artificial one. This operation usually improves sight and can be done on either one or both eyes. It is essential to see an optometrist regularly to monitor any changes in visual acuity, as early detection and treatment of cataracts can help forestall vision loss.

1. Nuclear cataract: This type of cataract occurs when the nucleus, or center, of the lens becomes cloudy.
2. Cortical cataract: This type of cataract affects the lens cortex, or the outer edge of the lens.
3. Subcapsular cataract: This type of cataract affects the back surface of the lens.
4. Congenital cataract: This type of cataract is present at birth or develops shortly after birth.
5. Traumatic cataract: This type of cataract is caused by an injury to the eye.
6. Secondary cataract: This type of cataract is caused by another condition, such as diabetes or medications.

1. Blurry vision
2. Difficulty seeing at night
3. Glare or halos around lights
4. Faded colors
5. Double vision in one eye
6. Frequent changes in eyeglass prescription
7. Poor depth perception
8. Sensitivity to light
9. Cloudy or filmy vision

Cataracts are identified through a thorough eye examination that involves testing for visual clarity, refraction, and an inspection of the lens and other parts of the eye. Your eye doctor may also utilize a slit-lamp microscope to inspect the lens and other parts of the eye. In some cases, a sonogram or other imaging tests may be utilized to diagnose cataracts.

Cataracts are caused by a dimming of the eye's natural lens, which is composed of proteins and other materials that can be harmed with the passage of time. Usual sources of cataracts are aging, eye injury, heredity, exposure to ultraviolet light, smoking, and certain medical issues such as diabetes.

Cataracts are remedied via surgery. During the operation, the hazy lens of the eye is taken out and substituted with a synthetic intraocular lens (IOL). The IOL functions to concentrate light onto the retina, permitting for better vision. The surgery is normally done on an outpatient basis and is viewed as secure and successful.

1. Put on sunglasses when outside: Wearing sunglasses can shield your eyes from the sun's ultraviolet rays, which can exacerbate cataracts.
2. Consume a nutritious diet: Consuming foods that are full of antioxidants, such as fruits, vegetables, and fish, can help preserve your eyes from harm caused by free radicals.
3. Stop smoking: Smoking increases the chance of developing cataracts and can worsen their progression.
4. Exercise regularly: Regular exercise can help reduce the risk of developing cataracts.
5. Wear protective eyewear: Wearing protective eyewear, such as safety glasses or goggles, can help protect your eyes from injuries caused by flying objects or debris.
6. Undergo regular eye exams: Regular eye exams can help detect cataracts early and allow for early treatment.
7. Utilize artificial tears: Artificial tears can help keep your eyes lubricated and reduce the risk of developing cataracts.
8. Use magnifying lenses: Magnifying lenses can help improve vision if cataracts make it difficult to see.
