识别和计算结膜充血和睫状淤血的百分比,并评估眼淤血的严重程度。

脂质层厚度

与标准模板相比,通过视频录制观察动态脂质层和分布。它有助于判断MGD。


眼睑边缘

高分辨率图像支持放大,以满足眼睑边缘整体形状及其轻微变化的检查要求。


角膜荧光素钠染色

专门设计的内置黄色滤光片,采用钴蓝色照明,可改善角膜钠荧光素的图像对比度。有效增加早期角膜上皮染色的阳性率。




角膜地形

勾勒角膜的轮廓

Lens Fitting

A simulated fluorescein image will be created based on patient’s cornea. The system will recommend several suitable lens for choose, which accelerates work flow and excludes unfit lens to save the trouble for patient to do real several fluorescein staining.


Research and develop with team SOS from EYE&ENT Hospital of Fudan University. Recommend the most precise lens based on the patient documentation.



Aberration & Simulation

Zernike wavefront aberration analysis makes plan of cataract and refractive surgeries visualized and ensures patient’s postoperative vision quality.
