Is that cataract? Cataracts are changes in the lens of the eye which should be clear and translucent, becoming cloudy so that the view is blurred and the patient cannot see clearly.
Cataracts occur slowly so that vision is disturbed in varying degrees according to the degree of lens opacification. The speed of cataract disorders in a person is unpredictable, because cataracts in each individual are different, even the development is different from one eye to the other.
The stages of cataract are divided into 3, namely:
- Immature cataract.
- Mature cataract.
- Hipermatur cataracts.
What Causes Cataracts
The process of moaning the lens when experiencing aging has not been clearly known. However, there are several factors that can increase a person’s risk of developing cataracts, including:
- Congenital or congenital, because his mother was infected with the virus during young pregnancy.
- As a result of inflammation or eye infection.
- As a result of diabetes mellitus.
- Use of steroid drugs.
- Eye injury.
- Too long exposure to UV light.
Symptoms of cataracts
Symptoms are blurred vision and like a hindering haze. Easy to glare in a bright place, double vision, the size of the glasses change. If these symptoms appear, it is recommended for a thorough examination by an ophthalmologist.
Keep in mind, that the symptoms of cataracts generally develop slowly. At first the patient will not realize there is a visual impairment, because only a small portion of the lens of the eye has cataracts. But over time, cataracts will worsen and produce the following symptoms:
- Double visible object.
- It’s hard to see clearly at night.
- Eyeglass lens sizes that change frequently.
- See halos around the light source.
Generally, cataracts do not cause eye pain, but sufferers can feel pain in the eyes, especially if the cataracts that are experienced are severe or have other eye disorders.
When should cataract be operated on?
Until now there are no medicines or foods that can cure cataracts. The only effective way is surgery. As for the prevention, protect the eyes so they are not exposed to UV light.
Surgery needs to be done if the cataract has disrupted daily routine activities and if the glasses are no longer helping. Cataract surgery can be done with local anesthesia or drops and without hospitalization.
In cataract surgery, a cloudy lens will be removed and replaced with an artificial lens. This artificial lens is made of plastic or silicon, and can be used for a lifetime. Whereas in conditions where artificial lenses cannot be installed, patients must wear glasses or contact lenses after cataract surgery to improve vision.
Cataract surgery is performed under local anesthesia so that the eyes become numb, and usually without hospitalization. Discomfort in the eyes is generally felt up to a few days after surgery. In patients with cataracts in both eyes, surgery is performed separately until the patient recovers from the first surgery, which is about 6-12 weeks.
Post Cataract Surgery
- The success rate of cataract surgery is quite high. More than 90% show improved vision if there are no disturbances or other problems in the eye.
- Most sufferers no longer need glasses after surgery to look far away, but some need the help of (but thin) glasses both to see far and near.
- Complications, although very rare, can occur during surgery or after surgery. If you experience discomfort in the eyes, see a doctor immediately.
- Sometimes the cataract is very cloudy, so that abnormalities in the back of the eye (eye nerves) are not seen during the examination. If this happens, even if the operation is successful, the vision does not necessarily mean significant improvement.
