Intraoperative measurement of intraocular pressure (IOP) opens up possibilities to investigate the influence of IOP on the stability of the eyeball during the performance of surgical maneuvers. Few techniques have been described, none of which are commercially available. This study investigated the use of sterilized probes for rebound tonometry, which could be used intraoperatively.
Tonometry was performed on 30 eyes using a noncontact tonometer and rebound tonometry with the iCare 100 and iCare 200 (iCare Finland Oy, Vantaa, Finland) in a sitting and in a supine position. When performing rebound tonometry probes from the package were used sequentially with sterilized probes. The comparability of sterilized and nonsterilized probes was investigated using different rebound tonometers and different settings.
Measurements on a sitting subject were comparable with sterilized and nonsterilized probes. Statistically significant comparability was also found in a supine position. Measurements with identically sterilized probes on identically positioned subjects were comparable with iCare 100 und iCare 200 (T2 vs. T4, p = 0.003 und T3 vs. T5 p < 0.001). The comparison of measurements of the original probe with the sterilized probe in a sitting and in a supine position were possible with statistical significance (p < 0.005). Measuring with the iCare 200 in a sitting position showed a slightly lower IOP with the sterilized probe with the difference being statistically significant.
Single autoclaving does not alter the probes' ability to measure IOP.
The use of probes which have been sterilized according to the regulations for other surgical instruments opens up new possibilities for the intraoperative measurement of IOP. This facilitates the use in scientific studies on surgical techniques. In the postoperative period the use of sterilized probes can reduce the risk of infection.
术中测量眼压（IOP）为研究手术操作过程中眼压对眼球稳定性的影响提供了可能。目前已描述的相关技术较少，且均未商业化。本研究探讨了可用于术中的经过消毒的回弹式眼压计探头的应用。
使用非接触眼压计以及iCare 100和iCare 200（芬兰iCare公司，万塔，芬兰）回弹式眼压计，对30只眼在坐位和仰卧位进行眼压测量。进行回弹式眼压测量时，依次使用包装内的探头和经过消毒的探头。使用不同的回弹式眼压计和不同设置，研究消毒探头与未消毒探头的可比性。
在坐位受试者中，消毒探头与未消毒探头的测量结果具有可比性。在仰卧位也发现了具有统计学意义的可比性。在相同位置的受试者上，使用相同消毒探头的测量结果与iCare 100和iCare 200具有可比性（T2与T4，p = 0.003；T3与T5，p < 0.001）。在坐位和仰卧位，将原始探头与消毒探头的测量结果进行比较具有统计学意义（p < 0.005）。在坐位使用iCare 200测量时，消毒探头测得的眼压略低，差异具有统计学意义。
单次高压灭菌不会改变探头测量眼压的能力。
按照其他手术器械的规定进行消毒的探头的使用，为术中眼压测量开辟了新的可能性。这便于在手术技术的科学研究中使用。在术后阶段，使用消毒探头可降低感染风险。
