Problem statement: According to the World Health Organization, cataracts are the leading cause of blindness in mid- and lowincome countries. India has the largest number of blind people globally—15 million—yet there is only one doctor for every 100,000 people, leaving the majority of cataract cases undetected.
Goal: To improve early cataract detection and free up the limited number of ophthalmologists to concentrate on surgery.
Solution: EyeCatra, a portable self-evaluation eye diagnostic tool that attaches to a cell phone and uses a light-scattering technique to scan and map the eye for cataracts. It can be used in rural homes, schools, pharmacies, and health clinics.
SDM contribution: SDM ’11 students Vivin Nath, Nirmalya Banerjee, and Rupreet Singh Soni are part of the EyeCatra team.
