In developed countries, vision care is taken for granted. Deteriorating eye sight can be remedied with glasses or contacts. More significant vision problem, such as cataracts or glaucoma, can be treated with the help of a specialist. In less developed countries the circumstance is quite different. In fact, for many patients it is often difficult, if not impossible, to obtain a routine eye exam. To address this need, Hong Sheng Chiong, a New Zealand-based ophthalmologist, has developed 3D printed eye examination tools to make eye exams more accessible. These tools can be used with an app and smart phone camera.
Typical exam equipment cost thousands of dollars. Chiong, realizing how expensive this can be, founded a research and development company specializing in mobile and low cost medical equipment for vision testing. The company, ODocs, has released a smartphone retinal imaging adapter and anterior segment adapter. These tools cost no more than $50 and have a 40° field view with 10x magnification. The parts can be 3D printed in about 4 hours and are readily assemble with only a few nuts and bolts.
Since its creation in 2014, oDocs has won several awards for innovation. Chiong and his team continue to work for results rather than praise. oDocs and the eye care industry look forward to seeing what this advancement will bring to those in developing countries around the globe.
*The equipment is open source so anyone can download it for free!
