Cataract - the essence of the disease

The term "cataract" (from the Greek. Kataraktes) means "waterfall". Under it means the defeat of the natural lens of the human eye - the lens. Representing a transparent biconvex formation, the lens is located in the eyeball. Its back is in contact with the vitreous body. Ahead is the iris.

The main function of the lens is to skip and refract light rays.

The effect of cataracts on visionThe lens is elastic. He is able, by changing the shape, to bring the focus almost at lightning speed. Due to this, an equally good visibility of objects near and far is ensured. However, as the aging blood supply is disturbed.The lens, deprived of good nutrition, becomes cloudy, losing transparency. As a result, less light enters the eye. This is the main cause of the disease called cataracts.

Eyesight, gradually weakening, becomes blurred, fuzzy. If you do not start treatment, the deterioration will progress. Often the neglected form leads to complete blindness. According to official data, this fate has not been avoided by 20 million people.

The main signs of the disease

To summarize, the symptoms of cataracts can be reduced to several points:

  • Manifestation of cataracts"Foggy" vision - a person sees as if through a waterfall or muddy glass;

  • in bright light around the objects are formed halos;
  • images split apart;
  • photophobia develops;
  • reading, writing and working with small objects is difficult;
  • in severe cases, the pupil becomes white.

Why does a cataract develop?

A number of negative factors can provoke the occurrence of the cataracts described above. The most common causes are:

  • Elderly woman with glassesnatural result of aging;
  • genetic (genetic) predisposition;
  • eye injury due to chemical or mechanical effects;
  • the result of other eye diseases - myopia of advanced form, glaucoma;
  • due to the general deterioration of the body condition - avitaminosis, diabetes, impaired metabolism;
  • Unfavorable ecological situationThe most common cause is poisoning by toxins, including: mercury, thallium, naphthalene, etc .;
  • smoking has a negative effect on vision, which is important to remember;
  • long-term use of strong medicines, including steroids;
  • exposure to radiation, infrared, ultraviolet radiation, microwave;
  • the cause of modernity is an unfavorable ecological situation.

Types of cataractsVarieties of cataracts

The disease has a peculiar classification:

  1. Nuclear cataract. Starts in the center of the core. Brown pigment can accumulate inside the lens. This symptom was the reason that the described form is also called brown cataract.
  2. Posterior cataract.The area under the back capsule of the lens becomes cloudy. Vision deteriorates quickly. Usually this type of disease is fixed in people of younger age - up to 60 years.
  3. Cortical cataract. Lens substance undergoes turbidity.Images of objects become blurry.

How is the most common form of the disease?

During the period of cataract development, if not treated, goes through several stages. Briefly about each of them:

  1. Initial stage. Most often manifested after 50 years. Duration in each case is individual: from several months to decades. At this stage, there is a clouding of the lens outside its optical part. The intensity of turbidity on the periphery, in different areas, is different. Usually a person does not notice that something is wrong with his vision. Many do not immediately sound the alarm, watching symptoms like doubling of luminous objects, flashing flies.
  2. Stages of development of the diseaseImmature (swelling) form. Opacities are observed in the central part of the lens. The vision drops noticeably, which the patient already clearly feels. The color of the pupil becomes grayish-white. The duration of this stage can be long.
  3. Mature form. The lens becomes completely cloudy, compacted. Vision decreases so much that a person feels only light. He is no longer able to distinguish objects. Treatment is needed, which means surgery to remove the lens.
  4. Overripe form. The lens fibers of the human eye are falling apart.The lens becomes less dense, is converted into a liquefied mass, within which the nucleus floats. The main symptom - its color becomes pure white. This is the last stage of the cataract.

Each case of cataract is individual, which requires a specific treatment. And yet the observations of doctors revealed some regularity.

In most patients, the stage requiring surgery comes after 6-10 years since the first symptoms appeared.

In some cases, the disease matures quickly (4-6 years) or vice versa - slowly (10-15 years).

How to recognize a cataract in time?

A cataract can develop over the years, but people do not even suspect it. Young people usually tend to ignore the first symptoms. Only when the disease is gaining momentum, many turn to the doctor.

Examination of the fundusThe best prevention of cataracts - periodic eye fundus examinations by oculists. The specialist conducts a survey using a slit lamp, which is also called a light. Having identified the disease, it determines its phase, measures intraocular pressure. If necessary, additional examinations are carried out.

Only when the diagnosis is known, the causes and degree of cataracts are clarified, is the treatment prescribed.

The main methods of treatment

Traditional treatment of the disease involves the use of an ultrasound method. Femtosecond laser is also widely used. The essence of the technique is the implantation of an artificial lens into the patient's eye. By such means intraocular lens, folding of the reference and optical segments.

IOL MasterBefore the operation, based on the symptoms revealed by the diagnosis, the doctor calculates the strength of the intraocular lens. Using the device "IOL-master"(Shown in the photo) records data on the length of the eye, the depth of the anterior chamber, etc.

During the operation, the opaque lens of the eye is replaced with an artificial lens. From now on, it will perform the function of refraction of light rays and imaging on the retina. The lens is made of a material that is biocompatible with eye tissues. Due to the supporting part, it is fixed inside the eye.

Surgical treatment is accompanied by the use of local drip anesthesia. Practice has shown that most patients easily tolerate it, regardless of age.

Ways of traditional medicine

At the initial stages of cataract development, many prefer to use folk remedies. Such a treatment is indeed successful. This is an effective prevention of the occurrence of complications.

However, blindly turn to alternative medicine is not worth it. It would be reasonable to consult an ophthalmologist on this matter. Based on what causes the lens of the eye, a set of procedures is appointed. As an addition to them, treatment with folk remedies can bring tangible benefits.

Girl applies eye dropsTreatment of folk remedies is presented very extensively and diversely. Eye drops are made from various plant components. These can be chamomile flowers and burdock leaves, onion or carrot juice, honey. Often used spring juice from pruned grapes. For rinsing the eye has proven itself tincture of calendula. Positive results help to achieve parsley juice, spinach, sage infusion.

All non-traditional means on which prevention of the development of the disease is based are not listed. Nature is rich in natural medicines, the healing power of which is amazing.

However, it should be emphasized once again: it is impossible to self-cure by one or another folk remedy. It is worth contacting the clinic so that the result of getting rid of a cataract problem is effective.
