Abstract

Background: To compare the measurements obtained from the Orbscan II, IOLMaster 700, Pentacam AXL, and Castroviejo caliper and their effects on calculating the recommended implantable collamer lens (ICL) size and postoperative vault measurements.

Methods: This is a retrospective cross-sectional study of patients who underwent ICL surgery by a single surgeon from March 1, 2018 to July 31, 2021. Records were reviewed for the anterior chamber depth (ACD) and white-to-white (WTW) measurements obtained from the Orbscan II, IOLMaster 700, Pentacam AXL, and Castroviejo caliper (WTW only). These were used to calculate the recommended ICL size. The actual ICL size implanted, and vault measurements obtained one month postoperatively were also collected.

Results: One hundred seven eyes with a mean age of 27.9 ± 7.7 years were included in the study. Mean WTW measurements were significantly different between devices (P < 0.0001), with the IOLMaster 700 having the highest value (12.14 ± 0.04 mm) and the caliper having the lowest value (11.45 ± 0.04 mm). Mean ACD measurements were the lowest in Orbscan II (3.12 ± 0.25 mm) and the highest in Pentacam AXL (3.16 ± 0.24 mm). The Pentacam AXL produced an ICL size similar to the Orbscan in 69.2% of eyes. The IOLMaster yielded an ICL measurement one size larger than Orbscan-based calculations in 64.5% of eyes. Using the Orbscan WTW and ACD, the desired vault of 0.25 to 0.75 mm and 0.25 to 1.00 mm was achieved in 70% and 91% of eyes, respectively. Substituting caliper WTW to IOLMaster 700 or Pentacam AXL WTW increases the percentage of achieving the desired vault to 80%, similar to the Orbscan.

Conclusions: The Orbscan II, IOLMaster 700, and Pentacam AXL cannot be used interchangeably for calculating ICL sizing. Combining the WTW from caliper measurement with the ACD of the IOLMaster 700 or Pentacam AXL could improve ICL sizing and achieve a higher percentage of eyes with the desired vault.

使用四种设备进行白对白测量的比较及其ICL尺寸的确定。

背景:比较Orbscan II、IOLMaster 700、Pentacam AXL和Castroviejo卡尺的测量结果，以及它们对计算推荐植入式晶体(ICL)尺寸和术后拱顶测量的影响。方法:这是一项回顾性横断面研究，对2018年3月1日至2021年7月31日期间接受单一外科医生ICL手术的患者进行研究。回顾了由Orbscan II、IOLMaster 700、Pentacam AXL和Castroviejo卡尺(仅限WTW)获得的前房深度(ACD)和白对白(WTW)测量记录。这些数据用于计算ICL的推荐尺寸。同时收集植入ICL的实际尺寸和术后1个月的穹窿测量值。结果:共纳入107只眼，平均年龄27.9±7.7岁。结论:Orbscan II、IOLMaster 700和Pentacam AXL不能互换用于计算ICL大小。将卡尺测量的WTW与IOLMaster 700或Pentacam AXL的ACD相结合，可以改善ICL的大小，并获得更高百分比的具有所需拱顶的眼睛。
