EYE-GO’s MistGo® Offers a BAK-Free Answer as Denmark Debates Toxic Eye Drop Preservative

A new DR article reports that Danish political parties, alongside Professor Miriam Kolko and the Danish Eye Association, are pushing for a ban on BAK (benzalkonium chloride) in eye drops. The preservative — found in an estimated 30–40% of multi-dose artificial tears sold in Denmark — is linked to eye surface damage, irritation, and worsened symptoms in long-term users.

The debate highlights a structural problem: most multi-dose eye drop bottles rely on preservatives like BAK to prevent contamination once opened. For patients on chronic eye medication, that trade-off can mean daily exposure to an irritant for months or years.

MistGo® was engineered with this challenge in mind. Our precision micro-dosing device enables multi-dose eye medication without dependence on BAK or similar preservatives — giving pharma partners a delivery format that supports both patient comfort and long-term adherence.

As the regulatory conversation around BAK continues, EYE-GO already offers a solution aligned with where the science — and now the political will — is heading.
