Existing drug delivery methods used to treat the front and back of the eye often cause discomfort for patients. Researchers at the Centre for Eye and Vision Research (CEVR) are studying how to create effective, non-invasive drug solutions that will both improve patient experience and the overall effectiveness of treatments delivered to the eye.
To help increase drug delivery to the front of the eye, researchers are leveraging 3D printing technology and light-activated materials that support a time-controlled release of medication using ocular inserts and contact lenses. This way, instead of applying multiple drops each day, patients would apply an insert at the base of their eye or wear a drug-releasing contact lens for up to one week.
For the back of the eye, researchers are leveraging innovative laser technology that would eliminate the need for patients with eye diseases, such as age-related macular degeneration, to require regular needle injections. Using first-of-its-kind laser technology, practitioners would be able to non-invasively eliminate excess blood vessels, as well as effectively slow the progression of the disease.
Through this leading-edge research, researchers are helping find efficient and comfortable methods of drug delivery to the eye – an ongoing challenge for vision scientists.
