Background

SIGNIFICANCE: The slit lamp is the gold standard ophthalmic instrument for examining the anterior segment of the eye.

Purpose

We demonstrate an autonomously aligning, contactless slit lamp enabled by a vision-guided robot to acquire anterior segment images without mechanical patient stabilization.

Results
86
ms
eye tracking kept the alignment beam locked on target almost instantly
More results

The device autonomously aligned to the eyes of in vivo human subjects, and we collected color images of the anterior segment during alignment.

“
Conclusion

These results demonstrate the feasibility of autonomous, contactless slit-lamp imaging through the use of robotic alignment and dynamic illumination. Such advancements could expand access to anterior segment diagnostic imaging.
