The unique* lipid replacement
EvoTears® OMEGA eye drops are the world’s first eye drops with the innovative substance perfluorohexyloctane and also the first water-free drops for the treatment of dry eyes. They are offered in a handy dropper bottle.
The EvoTears® OMEGA eye drops form a protective layer over the tear film. Consequently, they quickly and reliably prevent premature evaporation of the tear film and thus dry eyes. At the same time, vision is not impaired. As the products are free of additives they are very well tolerated.
Dry eyes are caused, for instance
- by a compromised lipid layer, i.e. premature evaporation of the tear film. In 58 % of dry eye patients this is the sole cause1,
- by a combination of compromised lipid layer and volume deficiency. This affects
31 % of dry eye patients1.
Because the EvoTears® OMEGA eye drops specifically address the problem with the lipid layer, they are suitable for almost 90 % of dry eye patients.

The EvoTears® OMEGA eye drops convince with decisive advantages:
1. EvoTears® OMEGA eye drops take on the function of the lipid layer
The lipophilic, i.e. oil-like property of perfluorohexyloctane allows it to take on the function of the lipid layer. The resulting effective protection against evaporation leads to patient satisfaction. In addition, the aqueous phase of the tear film is stabilised and watery eyes are prevented.
Thanks to the lipophilic property, a velvet-like feeling occurs when the drop spreads over the ocular surface.
2. Rapid spreading over the tear
Due to the low surface tension of perfluorohexyloctane, the drop spreads rapidly and quickly forms a protective layer over the tear film
3. High yield
The extremely low surface tension leads to the dispensing of a very small drop (about 10 μl). Consequently, with up to 280 drops per 3 ml content the product has a very high yield. In addition the drop volume corresponds to the capacity of the conjunctival sac. This ensures a pleasant application as little or no product will run out of the eye.
4. Long treatment duration
Thanks to the prolonged ocular retention time, the protection of the eye against evaporation is long-lasting. Combined with the high yield a bottle containing 3 ml offers a treatment duration of 35 or 70 days when applied 4 -times or twice a day respectively.
Due to perfluorohexyloctane, EvoTears® OMEGA eye drops are water-free. Microorganisms on the other hand depend on water for survival. Therefore, the products can be offered in a handy dropper bottle, even without the addition of preservatives.
6. No need for phosphates
The EvoTears® OMEGA eye drops, being water-free, do not have a pH and therefore do not need to be buffered. A pH outside the physiological range can cause a burning sensation. As buffer phosphate-containing compounds are often used, which, on an irritated ocular surface can lead to damage and thus visual impairment.
7. No need for emulsifiers
As EvoTears® OMEGA eye drops are not oil-in-water-mixtures there is no need for emulsifiers.
8. No visual impairment
The refractive index of EvoTears® OMEGA eye drops is equal to that of the tear and therefore they cannot impair vision.
9. No osmotic stress
Due to being water-free the EvoTears® OMEGA eye drops have no osmolarity. This prevents the ocular surface from being subjected to osmotic stress that can cause inflammation.
