摘 要：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 ***:This is a retrospective cross-sectional study of patients who underwent ICL surgery by a single surgeon from March 1,2018 to July 31,*** 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 *** actual ICL size implanted,and vault measurements obtained one month postoperatively were also ***:One hundred seven eyes with a mean age of 27.9±7.7 years were included in the *** WTW measurements were significantly different between devices(P0.0001),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 *** IOLMaster yielded an ICL measurement one size larger than Orbscan-based calculations in 64.5%of *** 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,*** caliper WTW to IOLMaster 700 or Pentacam AXL WTW increases the percentage of achieving the desired vault to 80%,similar to the ***:The Orbscan II,IOLMaster 700,and Pentacam AXL cannot be used interchangeably for calculating ICL *** 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.
