Low‐Cost 3D‐Printed Binocular Indirect Ophthalmoscope

Year: 2025

Type: article

Abstract: Background Currently available binocular indirect ophthalmoscopes are large and expensive. We sought to create a compact, low-cost 3D printed binocular indirect ophthalmoscope (BIO).Methods The BIO was made with off-the-shelf electronics and optical components, computer-aided design and a consumer-grade 3D printer. Ocular light safety was tested with a spectrometer.Results The component cost of the 3D printed BIO was $182.26. The wireless, spectacle-style BIO weighed 120 grams and was smaller than commercially available BIO’s, with the advantage of a battery incorporated into the frame. The BIO met the International Organization for Standardization’s standards for indirect ophthalmoscopes, as well as the American National Standards Institute’s Group 1 light hazard protection standards for ophthalmic instruments.Conclusions It is possible to produce a high-quality, low-cost BIO using computer-aided design and 3D printing. Such a BIO may be useful in both resource-rich and resource-limited settings.
