摘要

背景：比较IOLMaster和Pentacam在干眼症中的角膜测量结果。方法：对95例年龄相关性白内障干眼病患者122只眼进行研究。使用IOLMaster和Pentacam进行角膜测量，包括平角和陡角角膜测量(K)、平均角膜测量、平角轴、角膜前表面散光（A-ACS）。第二组检查在人工泪液注入1分钟后进行。比较使用人工泪液前后两种仪器的角膜测量值。分析了上述参数在各装置中的变化情况。结果：IOLMaster的平均平K值明显低于Pentacam。IOLMaster组a - acs明显大于Pentacam组，平均差异为0.46 D， 95% LoA上限为1.48 D，平K轴的95% LoA也超过了临床相关界限。人工泪液注入后，角膜测定仪和A-ACS测量值有明显改变。除A-ACS外，上述参数在两种设备间均无显著差异，平均差异降至0.17 D， 95% LoA为-0.20 ~ 0.54 D。设备内比较显示，IOLMaster测量的A-ACS及平K轴的变化大于Pentacam。结论：IOLMaster对干眼症角膜测量的影响明显大于Pentacam。对于两个装置之间A-ACS超过0.5 D的病例，建议在进行生物识别之前使用人工泪液。

Comparison of keratometry assessment between IOLMaster and Pentacam in dry eyes

Background

To compare the keratometry measurements between IOLMaster and Pentacam in dry eyes.

Methods

A total of 122 eyes of 95 age-related cataract patients with dry eye disease were enrolled in this study. Keratometry measurements including flat and steep keratometry (K), mean keratometry, axis of the flat K, astigmatism of anterior corneal surface (A-ACS) were obtained using IOLMaster and Pentacam. A second series of examinations were performed 1 min after instillation of artificial tears. Values of keratometry measured by two devices were compared both before and after using artificial tears. Changes of the above parameters in each device were also analyzed.

Results

The mean flat K of IOLMaster was significantly lower than Pentacam. A-ACS was significantly larger in IOLMaster than in Pentacam, with a mean discrepancy of 0.46 D and an upper limit of 95 % LoA of 1.48 D. The 95 % LoA for flat K axis also exceeded the clinically relevant margin. Keratometry and A-ACS measurements were significantly modified after instillation of artificial tears. None of the above parameters showed significant difference between two devices except for A-ACS, with the mean difference decreased to 0.17 D with 95 % LoA of -0.20 to 0.54 D. Intra device comparison showed that changes of A-ACS and flat K axis measured with IOLMaster were greater than those measured with Pentacam.

Conclusion

Dry eye has significantly greater impact on keratometry measured with IOLMaster than with Pentacam. For cases with A-ACS between the two devices over 0.5 D, artificial tears are recommended before performing biometry.
