The Ex Vivo Eye Irritation Test (EVEIT) in evaluation of artificial tears: Purite®-preserved versus unpreserved eye drops

摘要

Preservatives in artificial tears cause controversy. New developments such as the Purite® system have been introduced into the market, with the promise of little damage to the corneal surface. We wanted to give insight into the differences in the effect of preserved and unpreserved artifical tears on rabbit corneas cultured with the Ex Vivo Eye Irritation Test (EVEIT) system.
