Objective:

To introduce an ultra-low-cost, AI-powered portable scanning slit-light device for anterior-segment imaging and quantitative measurements.

Key Findings:

• The device costs under $500 and provides calibrated quantitative outputs.
• ACD measurements showed strong agreement with AS-OCT, with mean differences close to zero.
• Central corneal thickness (CCT) measurements exhibited wider variability due to spatial resolution constraints, approximately 40 µm per pixel.
• The device captures full-color anterior-segment images for qualitative assessment.

Interpretation:

The device may serve as a viable screening tool, approaching interchangeability with gold-standard imaging for ACD, while offering additional qualitative insights, particularly in community screening and teleophthalmology.

Limitations:

• Current prototype's performance for CCT is limited due to spatial resolution constraints, which may affect clinical decision-making.
• Intended as a screening tool, not a replacement for high-resolution imaging.

Conclusion:

This AI-driven platform represents a significant advancement in affordable anterior-segment diagnostics, particularly beneficial in resource-limited settings.
