The drug Kvinaks ophthalmologist prescribes in case it detects the patient's cataract . This disease is a clouding of the lens due to the denaturation of the protein that is part of its composition. A person with cataracts begins to see worse, feels turbidity in the eye. In extreme cases, the disease can lead to a complete loss of vision.
90% of cases of cataracts are recorded in people of senile age. Sometimes the opacity of the lens is congenital. Often cataracts result from mechanical damage to the eye, the action of infrared or x-rays, inflammatory eye diseases or diabetes, hypothyroidism .
Effect of the drug
Eye drops Quinaks readings have the following: cataract traumatic, congenital, senile, secondary. The main active ingredient is azapentacene, which contains 15 mg per 1 ml of the solution (ie, the concentration is 0.015%).
Included in the composition of Kvinax drops and such auxiliary substances as:
- propylparaben;
- boric acid;
- sodium borate;

- methylparaben;
- thiomersal.
The medicine is produced in sterile bottles and has a dispenser for convenient instillation of the eyes (instillation). It is a transparent liquid of red color.
According to the instruction, Quinax refers to substances that can regulate water-electrolyte, carbohydrate and protein exchange processes. Due to the action on the proteolytic enzymes of the anterior chamber of the eye, opaque proteins dissolve, and the clarity of the lens improves. Antioxidant effect of eye drops Quinax protects the sulfhydryl groups of the lens from oxidation.
Application of the drug
Use drops for the eyes of Quinax exclusively from the appointment of an ophthalmologist - the doctor orders the scheme of instillation individually.

Precautionary measures
For people wearing contact lenses, it is necessary to remove them before instillation, and to put on again only after 15 to 30 minutes.
