Problem statement: According to the World Health Organization, cataracts are the leading cause of blindness in mid- and low income 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.
