Drug Coating Technology for Therapeutic Contact Lenses Drug Coating Technology for Therapeutic Contact Lenses

Current treatment of ocular diseases such as glaucoma is predominantly managed using eye drops which have an extremely poor bioavailability (only 1-5% of the drug reaches its target) and are subject to poor patient adherence. With increased numbers of contact lenses users coming through into the population of newly diagnosed patients with chronic ocular conditions, using contact lenses as a means for delivery drug to the eye is an attractive approach to improve the drug absorption and therapeutic efficiency.

Overview

Researchers at The University of East Anglia have developed a novel method for printing drugs onto contact lenses to allow local and controlled drug release to the eye to significantly improve the management of chronic ocular diseases and patient adherence.

This technology allows the drug printing on existing commercially available disposable contact lenses that potentially would not affect vision. It can provide full control over multiple drug and dose combinations giving the potential for the development of personalised treatment and potentially treating multiple ocular conditions.

Advantages

  • Potential for personalised medicated contact lenses
  • Allows use with existing commercially available contact lenses
  • Little drug waste during drug printing
  • Patterned printing to avoid version disruption
  • Minimal effect on patient appearance

Applications

Pharmaceutical (ocular disease treatment and prevention).

Opportunity

The University of East Anglia is seeking co-development partners.
