Setting your eye clarity
Cataracts, colloquially called curtains or whitewater, are the discoveries that occur in the lens of the eye. The lens of the eye is behind the iris and pupil. Its task is to ensure the formation of images on the retina, which covers the inner face of the back of the eye and is sensitive to light. If the lens begins to blur, vision may deteriorate as the passing of the Rays will be blocked.
The loss of transparency of the lens immediately behind the pupil is called cataract. A change in the chemical composition of the lens also occurs when cataracts occur. However, the causes of this chemical change are not yet known. Cataract occurs in old age is the most known. However, this type of cataract is also found at fifty or even younger ages. In addition, metabolic diseases such as diabetes, drugs and eye injuries with cataracts can occur. Children can be born with inherited cataracts, as well as cataracts can occur in the first years of their lives.
Cataracts usually occur slowly. No pain,watering, Flushing. Some cataracts do not reach a level that severely reduces vision, while others prevent vision in its entirety. How a cataract affects vision:
1) prevalence
2) intensity,
3) depends on where it occurs in the lens.
The patient's usually complaints may include:
- There is also foggy, hazy, blurred vision, sometimes double vision; however, this condition usually disappears as cataracts progress.
- The need to change glasses often arises. However, when cataracts exceed a certain point, changing the number of glasses cannot improve vision.
- Don't feel like there's smoke in front of your eyes, don't look like you're looking after a tulle or a waterfall. Anyone with cataracts often blinks to see better.
- It's the change in pupil color that's usually black. When examining the eye, the pupil may appear gray, yellow, or white, but these changes may not always go unnoticed.
- Light problems, such as driving at night, become increasingly difficult because the misty part of the lens disperses the incoming headlight rays, causing them to appear double or dazzle the eye. People with cataracts also complain about not finding enough light while reading or doing close-ups.
Who should have cataract surgery? When should I have cataract surgery?
Cataract surgery should be taken when the visual impairment progresses enough to disrupt the person's daily life. If the Cataract has fully matured and become opaque like frosted glass, it should be treated more urgently. It is possible for a mature cataract to swell and even dissipate within the eye. Such changes are in danger of permanent loss of vision.
In congenital cataracts, surgery should be performed immediately in all cases where vision is blocked. Other than that, cases requiring immediate cataract surgery are very rare. Let's not forget that cataracts often progress after they start. But the pace of progress is usually slow and we can't pre-determine. The patient should determine the timing of cataract surgery. The duty of the physician is to determine how much of the patient's vision complaints are due to cataracts and to inform the patient.
Visual acuity is not the only criterion for the necessity of cataract surgery. Many patients may not complain about low visual clarity. Or they report that they are very uncomfortable in different light conditions, even though they have good visual clarity. There are many patients who complain that they see less on the street on sunny days, as well as those who complain that car headlights, street lights make excessive glare and reflection and darken their world at night.
One of the visual complaints of cataracts is the loss of contrast between shades of grey and colors. Because this process takes a long time, the patient may not perceive this change in two eye cataracts. Failure to notice bumps or potholes can cause them to have accidents while climbing stairs or jumping the threshold. The ophthalmologist warns the patients in this direction and asks the patient to make a decision.Hypertension is an old age disease. I'm young and I don't have hypertension. Wrong! Because this disease can occur in young and old people. It is even more dangerous, especially in young people. Because of the lack of symptoms and the development of vascular stiffness, the incidence of heart attack and stroke/stroke and therefore the risk of death is higher in young people..
Is cataract surgery a simple procedure?
It is not a strenuous surgery for the patient. The eye is numbed with drops or with a small amount of drug injection, so no pain is heard. Surgery can be considered an easy surgery for the patient as it usually does not exceed half an hour. However, this should not mean the simplicity of the surgery. It should be considered by experienced eye surgeons as an attempt to be done with care, and surgery should be performed by providing the best conditions.
How is cataract surgery performed?
There are several techniques. Depending on the condition of the eye and the patient, the surgeon will decide which technique to use. The purpose of the surgery is to remove all of the infected intraocular lens or the material inside it. When an artificial lens is not replaced by this natural lens, the patient will be confined to thick glasses. For this reason, the artificial intraocular lens should be placed in most patients.
Do cataracts recur?
Cataracts do not occur again in those who have cataract surgery. With the operation, the membrane (capsule) into which the lens is placed may become dense over time. Although this is popularly called “secondary cataract", it is not actually cataract. This formation can be easily treated with laser in a very short time. On the other hand, it is widely known among the public that laser cataract surgery is performed, but this operation is phaco method. Laser cataract surgery can be done. However, it is not widely preferred because it does not differ with phaco as a surgical technique.
