This file is part of a project developing 3D printed eye models for training clinical ophthalmology skills, including direct ophthalmoscopy and the Red Reflex Test. The major dimensions of the eye are based on MRI images of an infant eye. This posterior segment is fitted to an anterior cap, and can be modified to display a normative fundus or a variety of pathologies. This particular mesh presents with a central retinoblastoma tumor. Collectively, the anterior and posterior components are intended to be assembled and filled with water, resulting in an eye model with similar optical power to a slightly hypertropic eye (normal for healthy infants). 

We used the Vero family of photopolymers for printing, allowing for colour customization of the components. The model was designed in SolidWorks, therefore, metadata informing colour and material selection cannot be included in these STL files. To receive SolidWorks files with metadata, please contact Dr. Ashwin Mallipatna at ashwin.mallipatna@sickkids.ca 

Our prototype was printed using a Stratasys J750 Digital Anatomy printer. Details about development of the 3D model can be found in: Jane Walter, Kelvin Chau, Joshua Craig, Thomas Looi, Lothar Lilge, Ashwin Mallipatna, "3D-printed eye phantoms as physiological and pathological standards for training and instrument development," Proc.

This model was created by the Mallipatna Lab at the Hospital for Sick Children, Toronto, ON, Canada. Research for the validation of this model as an educational tool is ongoing. As such, the current version is not intended to be used as a replacement for validated clinical medical training.
