Drug-Loaded Contact Lens-Based Drug Delivery System

CD Bioparticles is a provider of drug-carrying contact lenses. Our experts specialize in develop a new generation of non-invasive drug delivery technologies that can overcome the ocular barrier for sustained drug release.

Introduction to Drug-Loaded Contact Lens

Topical drug delivery is the most widely preferred route of administration for the treatment of keratitis, conjunctivitis, dry eye, glaucoma, uveitis and other ophthalmic diseases. Drug-loaded contact lenses are a novel method of drug delivery by loading drug-active molecules (APIs) on a rigid or soft polymer device in contact with the cornea, continuously releasing the drug from the lens to the tear film, prolonging the residence time of the drug on the ocular surface, and improving bioavailability. Compared to traditional ocular drug delivery methods (eye drops, gels, etc.), contact lens-based drug delivery systems have the advantages of low drug side effects, high bioavailability, and ease of use.

The specific features of drug-loaded contact lens:

  • Continuous drug delivery, reducing the total drug dose and prolonging the    duration of drug action.
  • Improve drug delivery efficiency and bioavailability.
  • Easy to control and convenient to use.
  • Improve patient compliance and minimize adverse systemic side effects.

The applications of drug-loaded contact lens:

  • For the treatment of bacterial, fungal, viral keratitis.
  • For the treatment of dry eye, glaucoma and other eye diseases.
  • For the treatment of eye allergic diseases, such as: allergic conjunctivitis.
