About dispensing eye-drops
The eye-care industry has seen significant improvements both in formulations as well as in new dispenser technology for eye drops. The preservative most commonly used in eye drops is benzalkonium chloride, BAC, that was demonstrated to be harmful to corneal epithelial cells. Initially, unpreserved formulations were offered in mono-doses for single-use, today multi-dose preservative-free products have taken over significant market share. They offer more economical solutions and may be designed more ergonomically compared to single-unit doses.
With digitization the drug application as well as the remainder of the drug in the dispenser are monitored electronically, improving patient compliance.
