Unit-Dose Vials Displace Conventional Multi-Dose Bottles
Preservative-free unit-dose vials are increasingly displacing conventional multi-dose eye drop bottles as ophthalmic manufacturers seek documented formulation preservation alongside meaningfully reduced ocular irritation relative to conventional preservative-containing approaches. AptarGroup and Gerresheimer have both expanded unit-dose production capacity since 2023, targeting manufacturers that want validated sterile barrier data supporting reduced irritation risk relative to conventional multi-dose bottles. Smaller manufacturers are adopting this technology more slowly, constrained by the tooling investment required, but adoption is broadening steadily across major ophthalmic markets worldwide. Industry surveys suggest unit-dose conversion could accelerate further as reimbursement pathways clarify across the next several years.
