The Pascal Dynamic Contour Tonometer (DCT) is a slit-lamp mounted device developed by Ziemer Ophthalmic Systems that measures intraocular pressure (IOP) directly and continuously, independent of corneal thickness or rigidity. It provides ocular pulse amplitude (OPA), a parameter linked to glaucoma risk.

帕斯卡尔动态轮廓眼压计（DCT），是瑞士Ziemer眼科系统研发、可装配于裂隙灯的专用设备，能够直接、连续测量眼压，不受角膜厚度与角膜硬度影响；同时可提供眼脉搏振幅（OPA）参数，该指标与青光眼发病风险密切相关。（机器翻译）
