摘要
眼压(IOP)24 h的波动参数是眼科的一个重要的基础指标,目前传统的单个时间点的眼压测量无法有效地实现眼压的持续检测。基于眼压大小与眼角膜曲率的相关性,结合微机电系统(MEMS)微加工工艺和压模工艺,设计了一种基于电感的镜片式眼压传感器,在体外猪眼的实验结果证明了此传感器在眼压一定范围内(12~27 mm Hg)可以准确地反映眼压波动情况。
Fluctuation parameters of intraocular pressure（ IOP） is a key parameter in ophtalmology,current traditional single-time point measurement of IOP is unable to effectively realize continuous monitoring. An inductance-based soft contact lens IOP sensor is designed,combined with micro-electro-mechanical system（ MEMS） fabrication technology and molding transfer technology. Results in vitro test on cannulated porcine eyes shows that the sensor can accurately reflect the IOP fluctuations during certain range of 12- 27 mmHg.
