The human eye has an interesting and complex structure. The work of the visual apparatus directly depends on how closely a person monitors his he alth. If you do not contact a specialist in time, postpone visiting a doctor "on the back burner" when discomfort occurs, you can seriously harm the visual system.
In the era of progress, when almost every workplace has a computer, and at home there are TVs in all rooms, the eyes are under enormous strain. Constant tension and continuous contact with a bright screen leads to drying of the mucous membrane of the eye. The main symptom of a violation of the secretion of the lacrimal glands is a burning sensation, a feeling of sand under the eyelids.
To avoid dire consequences, ophthalmologists advise using tear fluid substitutes. These include the Vidisik gel.
High molecular polyacrylate in ophthalmology
Along with anti-inflammatory drugsprocesses, doctors began to prescribe Vidisik. Instructions for use of the gel says that this dosage form is used to protect the mucous membrane of the eye, as a replacement therapy.
Due to its interesting composition, Vidisik gel interacts with the mucins of the mucous glands of the eye, forming a thin film that protects the sclera from external stimuli.
Carbomer or Carbopol, is the main active ingredient, as well as a derivative of acrylic acid. To obtain a gel-like mass, the polymer is prepared in a special way in pharmaceutical factories. The resulting paste is used to prepare soft-based medicines.
What is it for?
The main specificity of all drugs used in ophthalmic practice is considered to be full compliance with the physiological characteristics of the mucosa. The film obtained during application becomes an excellent remedy for people suffering from dry eye syndrome, mucosal irritation and inflammatory diseases of the conjunctiva.
In addition, "Vidisik" gel is an adjuvant for violations of the production of lacrimal fluid, to restore the mucosa after injuries.
How to use
The period of interaction between carbomer and cornea is one and a half hours. It can be used up to five times a day, or even more, one or two drops in each eye. Before going to bed, it is advisable to carry out the procedure half an hour before bedtime.
But don'tforget that the duration of treatment depends on the problem, and the attending ophthalmologist prescribes the gel.
Overdose and side effects
Information about an overdose of this drug has not been reported, since the active substance in the gel is in a small amount.
But there is a possibility of a temporary worsening of symptoms: burning, pain. This is due to the presence of a preservative, which, with prolonged use, can give a similar result in the form of irritation, damage to epithelial cells on the mucous membrane of the eye.
Manufacturer advises people who constantly use moisturizers to change it to a dosage form without preservatives.
Interaction
As you know, any barrier agent affects the ability to be absorbed from other substances. Vidisik is no exception. Given its ability to retain moisture, it can prolong the effect of drugs used in the complex therapy of "eye" diseases.
Therefore, the interval for taking various drops together with Vidisik gel in the instructions for use is indicated - at least five minutes. Ideally fifteen. The main point: the gel is applied last.
Pregnant, lactating and children
Expectant mothers can use Vidisik gel. The instructions for use say that its use is possible if the expected benefit outweighs the risk to the fetus. Although the composition of the drug includes substances that have almost no effect on the functioning of internal organs and systems.
Clinical research on thiscategories of the population have not been conducted, but given the chemical properties of the substance, after consultation with a doctor and under his supervision, admission is possible.
If there is no "Vidisika" in the pharmacy
Few people have not encountered such a situation when, having come to the pharmacy, they could not get the right drug, and there is simply no time to look for it. You can purchase an analogue that, in terms of pharmacological properties, resembles Vidisik. The pharmacy sells various products that can partially or completely replace the gel.
All preparations containing carbomer are produced in Europe and America, therefore the quality standards of these dosage forms are high.
Full analogues of Vidisik gel should contain only carbomer, have a gel-like consistency. These include:
- "Sikapos". Eye gel made in Germany in a small tube weighing ten grams. Contains carbomer. Used up to five times a day, one to three drops. The peculiarity of the product is that when interacting with the lacrimal fluid, the base dissolves under the action of s alts, and the sclera is moistened with the active substance, relieving inflammation and irritation of the mucosa.
- Oftagel. The difference between this remedy and others is that, in addition to carbomer in a larger amount (2.5 mg per gram of the drug), it contains benzalkonium chloride, which is not recommended for use with contact lenses. Before instillation, it is advisable to remove the lenses, and after the procedure, wait fifteen minutes. Applied one to four times a day for treatment"dry eye syndrome", inflammation of the conjunctiva and cornea of the eye. Produced in Finland. If there are no complete analogues in the pharmacy, then you can replace it with other means that do not differ from the Vidisik gel by indications, but contain hypromellose.
- "Artificial tear". It is produced by the Belgian company Alcon, which has long been known in the pharmaceutical market as a company dealing exclusively with eye preparations.

Since the product has only barrier properties, it can be used by pregnant and lactating women, as well as children with caution. It is prescribed for dry mucous membranes, burning sensation, discomfort and pain. Adults are given one or two drops as needed.
