Fig. 6: Evaluations of contact lens sensor in the human eye.
From: LC contact lens sensor for ultrasensitive intraocular pressure monitoring
a Photograph of the human eye wearing the contact lens sensor. b Slit-lamp fluorescence examination of the corneal surface after 6 h wear of the contact lens sensor. c Time-varying changes in resonance frequencies and Icare IOPs under the head-down bed-rest experiment. d Calibration of the sensor resonant frequencies (Mean ± SD) versus with IOPs in the human eye. e Time-varying changes in IOPs (Mean ± SD) obtained with the contact lens sensor and Icare tonometer, respectively, for 5 h. Figure 6a was created by authors Hongbin An, Xian Wang, Zhikang Liao, Hui Zhao, and Yingyun Yang. In which, Hongbin An wore the contact lens sensor, Xian Wang and Zhikang Liao performed the LC signal acquisitions and IOP measurement, Yingyun Yang and Hui Zhao assisted and took the photograph. Figure 6b was created by author Yingyun Yang using the slit-lamp microscope (SL-D7; Topcon Medical System, Tokyo, Japan). Figure 6c–e were created by author Hongbin An and the results were discussed with Hui Zhao, Yingyun Yang, Jizhou Song, and Yinji Ma.
