What is cataract

A cataract is called turbidity of a special optical lens located inside the eye and responsible for the refraction of the rays - the lens.If the problem arises, then the key property of the lens, transparency, disappears, it becomes cloudy.

It is interesting that this disease is translated from the Greek only as a "waterfall". But it's not just that. The fact is that a person suffering from a disease sees everything as if through a flowing stream of water, his perception of the surrounding reality is visibly distorted.

Causes of appearance and symptoms

Cataract can be both congenital and acquired disease, it can develop both on one eye, and immediately on both.In a congenital variant, it is usually the case that during pregnancy, the mother suffered a severe infectious disease and / or took potent medicines.

The purchased option most often develops in the following situations:

  • trauma to the eye;
  • operations affecting the head;
  • glucocorticoid or radiation therapy;
  • diabetes;
  • age changes.

The latter reason is the most common, because approximately every second person has a clouding of the lens after reaching 50 years of age.

The symptomatology of this pathology is problematic enough to track, because it manifests itself very smoothly, gradually, it is very difficult to detect if you do not previously consult a specialist.A person simply begins to gradually realize that something is wrong with his vision, he begins to see that he has stripes and white spots flashing before his eyes, the image begins to double. When reading, the eyes begin to get tired very quickly, and the work with small objects begins to be problematic.

If the problem is too much started, then it can be seen even from the side, because the color of the pupil changes from black to white.

The development of the disease can take a very long time, sometimes it develops to fifteen years.And if it developed so much, then it is necessary to provide surgical treatment, which is carried out through surgical intervention.

Cataract removal

If the disease is highly developed, then the removal of cataracts is simply necessary, which is almost always understood as surgical removal.

Methods of treatment

The simplest method of treating cataracts is medication.It is carried out quite simply, you only need to use drops that contain antioxidants, potassium iodide, amino acids, necessary vitamins and so on.This treatment can be effective only at very early stages, it can slow the progression of the disease, but not completely prevent it. In any case, you can use the reviews on cataract treatment, and what people specifically came up with.

It is recommended not to avoid more radical treatment, because it is more effective.

Surgical intervention

Where it is better to get rid of the problem with surgical intervention? This is a fairly simple operation that can be carried out in any ophthalmological clinic.The bottom line is that the affected lens is replaced with a special artificial lens. Cataract is removed by several different methods - either with ultrasound or with a special laser.The operation is called "phacoemulsification". To do this, make local anesthesia with drops. This anesthetic is very well tolerated. The only thing is that the prices for cataract surgery are quite large, that's why surgical intervention is used last.

Possible complications

In most cases, the operation is successful, no problems arise.But nevertheless there are various complications which in rather rare or infrequent cases are shown. These include:

  • Hemorrhage in the anterior chamber.This problem occurs rarely, only if the iris is damaged. Blood dissolves without outside interference for several days.
  • Detachment of the retina.This is a rather serious complication, which most often occurs in short-sighted people. Requires re-intervention to eliminate.
  • Elevation of intraocular pressure.The reason is the clogging of the drainage system. It is often solved by drops, sometimes by physical intervention.
  • Lens shift.This is a serious deviation, which requires lifting the lens.
  • Secondary cataract.It is corrected with the help of capsulotomy.

Do not be afraid of these complications. Virtually all of them can be fixed and are only temporary inconveniences.
