Contact Lens as Ocular Drug Delivery Device

More about the book

The potential for soft contact lenses to deliver drugs to the eye was first described by Sedlacek. Since then many studies have been investigated the ability of contact lenses to improve the corneal permeation and bioavailability of topically applied pharmaceutical agents. Lenses soaked in drug solution could be applied to the eye. This method could be employed with antibiotics for severe infections. The said approach could prolong the contact time of the drug with the cornea and thus improve penetration of drug through the cornea.
