Above all, eye drops should have good tolerability and be germ-free in order to protect sensitive eyes. Eye drops can contain preserving agents such as benzalkonium chloride in order to prevent them from being contaminated with germs. However, these additives are not harmless: they can cause allergies, impede the regeneration of eye tissue and further reinforce the symptoms of dry eyes.
In order to avoid this problem, URSAPHARM has developed the innovative COMOD® system entwickelt: it keeps the liquid sterile as well as sealed airtight and thereby makes it possible to do completely without preservatives of any kind. All eye drops in the HYLO® EYE CARE family are supplied in COMOD® system bottles and are therefore preservative-free, have a long life and can also be accurately dispensed.
This is how the COMOD® system works: sterile without preserving agents
Our innovative COMOD® dosage system is purely mechanical. The liquid on the inside is packed in a flexible, airtight sachet and at no point comes into contact with the surrounding air. By operating the pump system, the sachet on the inside collapses gradually. The pressure equalization is effected by the intake of air into the space between the inner sachet and the container wall. In this way, the internal sachet stays sealed and the liquid is protected against contamination from the air. The contents remain sterile for a period of use of 6 months – all without preservatives.
Drop-by-drop dosage with the COMOD® system
In addition, the COMOD® dosage system makes it possible to dispense exactly one drop per pump stroke. This means the contents go a long way. Each bottle with 10 ml content can provide at least 300 drops. The output of liquid is precisely dosed by the valve system. Every time it is used, the drop dispensed is the same size so that a constant, reliable effect is produced.
COMOD® system or single-dose container?
The COMOD® system system offers more benefits when compared to single-dose containers, which are produced for one-time use. The high-quality COMOD® bottles have a smooth dropper tip. In contrast, ripping open the single-dose containers creates sharp-edged drop openings which increase the risk of injury to the eyelid margin or the eye. The COMOD® system thus provides additional safety for your eyes. The COMOD® system also has benefits with regard to the environment: compared with single-dose containers, the COMOD® bottles produce less packaging waste.
How to use the COMOD® bottles
