Intraoperative measurement of intraocular pressure using a handheld rebound tonometer with sterilized probes: simple method for intraoperative tonometry

Abstract

This article describes the utilization of a commercially available device for intraoperative measurement of intraocular pressure (IOP). The presented technique will enable a better understanding of intraoperative dynamics using a commercially available device. 261 phakic eyes were included. Measurements were conducted using the iCare 200. The probes were autoclaved at 134°C for 5 minutes. A successful measurement was achieved in 100% of cases. In 2 cases (0.67%), the initially used probe had to be replaced to conduct a successful measurement. The use of sterilized probes in rebound tonometry is a safe and valid method for intraoperative IOP measurement. This enables, for the first time to the authors' knowledge, precise measurements according to modern standards using commercially available devices. This method will support further investigations into surgical techniques and materials, as well as surgical education.
