Astigmatism Correction Using SMILE
Asia - Pacific Journal of Ophthalmology, 2019 Small incision lenticule extraction (SMILE) was introduced in the recent decade for the treatment of myopia and myopic astigmatism. This flap-free technique has a high efficacy and safety profile and also carries potential advantages over laser in situ ...

Spin‐Orbit Photonics with Potato Starch Lenses
Advanced Optical Materials, EarlyView.Native potato starch spherulites are introduced as volumetric optical elements that modulate both dynamic and geometric phases of light. These spherulites focus light and generate optical vortices via spin‐orbit interaction, functioning as polarization‐sensitive microlenses. Their unique radial anisotropy enables applications in vortex beam generation,

Waveguide‐Based Retinal Projection Near‐Eye Display with Bidirectional Eyebox Expansion
Advanced Intelligent Systems, EarlyView.A waveguide‐type retinal projection display system with bidirectional extended eyebox is proposed. The two‐layer holographic optical elements (HOEs), with two eye reliefs of 11 and 12 mm in the axial direction, serve as the image combiner, and each layer of HOEs generates two viewpoints with a horizontal spacing of 5 mm. Based on the mechanism of human
