Experimental lens design delivers medicine from the periphery.
Researchers say contact lens-based medicine could benefit patients who suffer from glaucoma, The Telegraph reports. According to the article, the technology delivers medication gradually and with more precision and comfort than eye drops. "We found that a lower-dose contact lens delivered the same amount of pressure reduction as the latanoprost drops, and a higher-dose lens, interestingly enough, had better pressure reduction than the drops in our small study," says Harvard Medical School ophthalmologist Joseph Ciolino. The experimental contact design dispenses medicine from its periphery, so the center of the lens is clear. The researchers are designing clinical trials for humans.
