Development of an Application for Aid in Cataract Screening

Cataract is the main cause of reversible vision impairment in developed countries, and at the age of 70, almost all of them will have developed some degree of it. `Cataract' is the name given to any congenital or acquired opacity in the natural lens capsule or substance of the eye. In this context, this paper presents TriOft, an embedded teleophthalmology system, which uses the smartphone, for cataract screening. This application makes possible using the cell phone as a tool, considering its easiness for handling and transporting, as well as the benefits for the more remote regions, where there is no an easy access to a doctor, specialized or not.
