Besides correcting vision, contact lenses may be potential treatment devices to relieve eye pain, help the cornea to heal from injury, protect and hydrate the surface of the cornea from dry eye disease, and deliver medications to the eye.

Many ocular conditions like allergic conjunctivitis, dry eye, and glaucoma are treated using eye drops. It is estimated that 95% of the active ingredient in the medication may be lost through tear drainage. Technological advancements have made it possible to use soft contact lenses to deliver a continuous release of medication over a duration of time to treat ocular conditions and disease.

The ability of the soft contact lens to absorb and release a drug is based on the contact lens material. Their potential as a treatment depends on the water content, the thickness of the lens, the molecular weight of the drug, the drug concentration, and the time it remains within the lens. 

Topical eye drops can be an inconvenient burden for patients. Delivering medication by way of a contact lens has many benefits and offers a glimpse into the future of treatment.

Let’s look at the potential benefits of using contact lenses to deliver medication to your eyes.
