In this report, we have utilized a smartphone-based innovative tool named anterior segment photography with an intraocular lens (ASPI) with a cobalt blue filter on the smartphone flash for photographing fluorescein-stained corneas. An intraocular lens along with a cobalt blue filter was attached to the smartphone camera to achieve this purpose. The filter could block out all wavelengths of light except the blue wavelength (450-490 nm) emerging from the smartphone camera. A pilot study was conducted on 27 eyes of 25 patients where images of various corneal pathologies were obtained using ASPI blue light imaging. The images were clear and highly magnified and could be used for documentation, teleconsultation for expert opinion, education, and monitoring of disease progression. ASPI-aided blue light imaging could be easily fabricated and is a frugal inexpensive device, which is used by different ophthalmic personnel to obtain fluorescein-stained corneal images.
在本报告中，我们利用了一种基于智能手机的创新工具，名为前节照相与人工晶状体（ASPI），在智能手机闪光灯上使用钴蓝色滤光片拍摄荧光素染色的角膜。将人工晶状体和钴蓝色滤光片连接到智能手机相机上以实现这一目的。该滤光片可以阻挡除了从智能手机相机发出的蓝色波长（450-490nm）以外的所有波长的光。在 25 名患者的 27 只眼中进行了一项初步研究，使用 ASPI 蓝光成像获得了各种角膜病变的图像。这些图像清晰且高度放大，可以用于记录、远程咨询专家意见、教育和监测疾病进展。ASPI 辅助的蓝光成像可以很容易地制作，是一种廉价的设备，不同的眼科医务人员都可以使用它来获取荧光素染色的角膜图像。
