Contact Lenses Developed to Treat Glaucoma, Halt Vision Loss


Glaucoma is a silent stealer of sight. It’s the second leading cause of blindness, but currently there is no known cure for the disease. However, scientists have developed new contact lenses containing a nanodiamond medicine gel to deliver glaucoma drugs to the eye and stop vision loss.

Understanding glaucoma
Glaucoma is considered a complicated disease. It attacks the optic nerve by causing a buildup of fluid in the eye, damaging tissue that regulates fluid drainage and creating irreversible vision loss. According to the Glaucoma Research Foundation, the disease affects more than 2.2 million Americans. Most people with glaucoma do not experience any early warning signs or symptom. If not treated promptly, victims may experience vision loss or permanent blindness.

New treatment solution
In the past, medical professionals treated glaucoma patients with eye drops designed to reduce fluid and help drain it from the eye. However, researchers found that as little as 5 percent of the drops actually reach the affected area.

Recently researchers at the University of California, Los Angeles created contact lenses embedded with a nanodiamond medicine gel designed to interact with the patient’s tears and treat glaucoma. The research team explains that nanodiamonds are shaped like small soccer balls, about 5 nanometers in diameter.

Although nanodiamond-embedded contact lenses are considered a more effective option for treating glaucoma, researchers continue to explore ways to eradicate the disease.
