Canasol
Canasol, a ganja-based medicine that helps decrease intraocular pressure with none of the side effects caused by other treatments, was developed through the hard work and scientific research of two notable Jamaicans: pharmacologist Professor Manley West, and ophthalmologist Dr. Albert Lockhart. It was an important breakthrough drug as it was the first glaucoma eye medication in the Caribbean to be developed at the University of the West Indies, Mona.
The JaipurKnee
A young Jamaican native, Joel Sadler, co-developed the affordable prosthetic knee with his Stanford University teammate, Eric Thorsell, and the Jaipur Foot Group, a charity that provides prostheses to Indian amputees. The prosthetic knee is now being used by thousands of amputees in India. Time magazine rated the JaipurKnee No. 18 on its 50 best inventions of 2009 list. Sadler was only 25 years old at the time.
