In the summer of 2016, I worked at the Srujana Innovation Center at LV Prasad Eye Institute (LVPEI) in Hyderabad, India. I worked on my own project, titled Bullseye, which is a cost effective corneal topography device

that attaches to smartphones for rapid imaging of the surface of the cornea. 

Bullseye was developed to bring corneal topography technology, which is used to diagnose keratoconus, to rural clinics that would otherwise have no access. Bullseye is very small and attaches to any smartphone, only using the phone’s camera and flash to get images of the cornea that can be interpreted through corneal topography software. The project received the Tej Kohli Cornea Institute (TKCI) - Srujana Innovation Award, providing it with the funding and resources for the project to be brought to market within a year.

My Contribution

I was the only person working on this project during my internship at LVPEI. I fabricated the prototypes using 3D printing and tested the design using my iPhone camera. However, there was a weeklong workshop at the end of my internship, Engineering the Eye, where participants came from all over India to collaborate with Srujana. The interns were all team mentors for their projects, so I mentored a team of five people who mainly worked on app development for Bullseye.
