Summary
Researchers developed a low-cost, 3D-printed binocular indirect ophthalmoscope (BIO). This compact, wireless device meets safety standards and offers a portable solution for eye examinations in diverse settings.
Area of Science:
- Ophthalmology
- Biomedical Engineering
- Medical Device Design
Background:
- Existing binocular indirect ophthalmoscopes (BIOs) are often bulky and costly.
- There is a need for more accessible and portable ophthalmic diagnostic tools.
Purpose of the Study:
- To design and fabricate a compact, low-cost binocular indirect ophthalmoscope (BIO) using 3D printing technology.
- To evaluate the performance and safety of the 3D-printed BIO.
Main Methods:
- Utilized off-the-shelf electronics and optical components.
- Employed computer-aided design (CAD) and consumer-grade 3D printing for fabrication.
- Conducted ocular light safety testing using a spectrometer.
Main Results:
- The 3D-printed BIO cost $182.26 to assemble.
- The wireless, spectacle-style device weighed 120g, was more compact than commercial alternatives, and featured an integrated battery.
- The device met International Organization for Standardization (ISO) and American National Standards Institute (ANSI) safety standards.
Conclusions:
- High-quality, affordable binocular indirect ophthalmoscopes (BIOs) can be produced via CAD and 3D printing.
- This innovative 3D-printed BIO presents a viable option for both well-resourced and resource-limited clinical environments.
- The development facilitates improved accessibility to ophthalmic examination tools.
