摘要

To assess a possible signal drift, noise and influences of electromagnetic radiation on the measurement behaviour of the Triggerfish? contact lens sensor, which might be mistaken as IOP fluctuations. Contact lens sensors (Triggerfish?, SENSIMED AG, Lausanne, Switzerland) were fixed in a water bath. To reduce any external electromagnetic impulses, all plugs were removed from the sockets, no lights were switched on and no electronic devices, except a temperature logger were left in the test room. For 24?h signal drift, noise and the influences of a cordless telephone (Ascom d43 DECT Handset, EU DECT 1880-1900?MHz, Ascom Wireless, Baar, Switzerland), a smartphone (Sony Xperia Go ST27i, Sony Corporation, Tokyo, Japan) and a computer (Hewlett-Packard ProBook 650 15,6″ - D9S33AV, Hewlett-Packard Inc., Palo Alto, USA) on the measuring profile were analysed. Twenty-four-hour measurements without provoked external electromagnetic impulses yielded a profile without any signal drift and 8.2?mV?eq noise. During the activation of the cordless telephone a maximum measurement variation of 3.2?mV?eq. (4.1-7.3), smartphone 1.8?mV?eq. (4.7-6.5) and computer 1.4?mV?eq. (6.3-7.7) were observed. During 24-h measurements there was no signal drift and a very low noise. Patients concerned about electronic devices possibly interfering with the measurements of the contact lens sensor, can be informed, that the use of their cordless telephone, smartphone or computer does not cause any problems. The amount of the signal noise might help to define actual IOP fluctuations. Temperature fluctuations might influence the measuring profile.
