Mechanism of action

Suppresses holding not only pain, but also impulses of other modalities. The action develops in 20-30 seconds after application and lasts up to 15 minutes.

Indications and usage

Dosage and administration

When performing tonometry and other procedures of a short duration, 1-2 drops are instilled immediately before the examination.

With prolonged anesthesia (during cataract removal) - 1-2 drops every 5-10 minutes (3-5 doses). After surgical manipulation it is necessary to cover the eye with a bandage, since The blink reflex is temporarily eliminated.
