3DEyes Created for Training

Students of engineering at the University of Toronto have created a 3D-printed eye they believe could be used to help ophthalmology students train on ultrasound eye exams.

The students came up with the concept when working on the Innovation, Hammers & Nails Initiative, a collaboration between the Institute of Biomaterials & Biomedical Engineering (IBBME) and the Hospital for Sick Children (SickKids) launched in 2015.

‘Nails’ refer to challenges faced every day at hospitals and ‘hammers’ are the new devices, systems and solutions designed by IBBME researchers. Anyone from the hospital is able to propose a challenge.

Student Rachel Reding conceived the 3D eye having observed the procedure of doing an ultrasound diagnosis on the eye.

“The training that they use right now involves doctors examining each other or healthy volunteers, which doesn’t really give them the chance to see the symptoms of eye diseases,” she said.

Ms. Reding and her team used a 3D printer to create a plastic human face and a series of removable eye models. When filled with water, the simulated eyes reacted to ultrasound in a very similar way real eyes. Printed physical features on the inside of the eye mimicked the telltale signs of various conditions: for example, a mushroom-like shape is indicative of melanoma. The model featured a pulley system that could move the eyes left, right, up and down, allowing the user to focus on different parts of the eye.
