Beautiful Article on Dr. V, the catarct surgeon from India. This is a slightly older article. But recently he was discovered by a San Francisco businessman and investor named David Greene. David learned that Dr. V used his profits from cataract surgeries to fund the charitable surgeries that he did for free. They also discussed his business model and found that he spent about 600$ for each pair of artificial lenses he installs on his patients. David Greene then setup a manufacturing plant, which manufactures and sells these lenses to Dr. V for a little over 4$ and still makes a profit. This means that Dr. V now can put in $596/- more of profit towards charities. He has done well over a quarter million free cataract surgeries and restored eyesight for the poor in Southern India. Just simply beautiful.
