The increasing number of cataract sufferer is a serious problem because cataracts are a leading cause of blindness in the world. To avoid blindness from cataracts we need to detect them early.

Unfortunately, a lot of developing countries have a limited number of ophthalmologists and health facilities, while a lot of cataract sufferers live in developing countries. In our system, once a user simply takes a patient’s photograph of an eye, the system will automatically analyze the image and distinguish between serious and non-serious conditions.

Our system performance is promising for further development.
