Contact Lens with Moiré Patterns for High‐Precision Eye Tracking

Advanced Functional Materials, Volume 36, Issue 29, 9 April 2026.
This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.

Knowledge based automated planning for non‐coplanar VMAT stereotactic radiosurgery in ocular malignancies

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background and purpose Stereotactic radiosurgery/radiotherapy (SRS/SRT) has emerged as a less invasive alternative to enucleation in the management of ocular malignancies. SRS/SRT planning is time‐consuming, complex, and the plan quality depends on the experience of the treatment planner.

Dynamic Retinal Pathology in Glaucoma Progression Revealed by High‐Resolution Functional Imaging In Vivo

Laser &Photonics Reviews, Volume 20, Issue 5, 6 March 2026.
In this work, we investigated the dynamic retinal pathology of glaucoma from onset to late stages through longitudinal in vivo high‐resolution imaging in a silicone oil‐induced ocular hypertension (SOHU) glaucoma mouse model. We developed an optimized adaptive optics two‐photon excitation fluorescence microscopy (AO‐TPEFM) technique for morphological ...
