To assess the relationship between postoperative implantable collamer lens (ICL) vault and lens height obtained from two different measurements.
A retrospective case series study enrolled eyes with horizontally implanted ICL. Crystal lens rise (CLR) and the distance between STS plane and anterior crystalline lens surface (STSL) were measured in the horizontal and vertical directions using ultrasound biomicroscopy (UBM). We compared the differences in the parameters measured in both horizontal and vertical directions. The participants were categorized into three groups according to ciliary sulcus width (CSW) which is defined as the distance between the posterior angle of the iris and the anterior angle of the ciliary process: narrow CSW group (NSG); medium CSW group (MSG); and wide CSW group (WSG). The correlations between CLR/STSL and vault were examined in each of the three groups. Biased correlation analysis was used further to contrast the correlation between CLR/STSL and vault.
This retrospective study included 223 myopic eyes. Vertical STSL (VSTSL) and vertical CLR (VCLR) exhibited significantly greater values compared to their horizontal counterparts (both P < 0.05). None of the indicators were statistically different between the three groups. In both NSG and MSG, STSL/CLR correlated with vault, while in WSG, only STSL correlated with vault (r=-0.316, P = 0.013). In contrast to HCLR, the correlation between HSTSL and vault remained after controlling for HCLR (r=-0.162, P = 0.015).
STSL should deserve more attention in the preoperative evaluation of ICL compared to CLR especially when CSW is large.
评估两种不同测量方法得出的术后可植入 Collamer 透镜（ICL）拱高与晶状体高度之间的关系。
回顾性病例系列研究纳入了水平植入 ICL 的眼。使用超声生物显微镜（UBM）在水平和垂直方向上测量晶体状晶状体上升（CLR）和 STS 平面与前晶状体表面（STSL）之间的距离。我们比较了两种方向测量参数之间的差异。根据睫状沟宽度（CSW）将参与者分为三组：窄 CSW 组（NSG）；中 CSW 组（MSG）；宽 CSW 组（WSG）。检查了每组中 CLR/STSL 与拱高之间的相关性。进一步使用偏相关分析对比了 CLR/STSL 与拱高之间的相关性。
本回顾性研究纳入了 223 只近视眼。垂直 STSL（VSTSL）和垂直 CLR（VCLR）的值明显大于其水平对应值（均 P<0.05）。三组间的指标均无统计学差异。在 NSG 和 MSG 中，STSL/CLR 与拱高相关，而在 WSG 中，仅 STSL 与拱高相关（r=-0.316，P=0.013）。与 HCLR 相比，在校正 HCLR 后，HSTSL 与拱高之间的相关性仍然存在（r=-0.162，P=0.015）。
与 CLR 相比，在 ICL 的术前评估中，STSL 应受到更多关注，尤其是在 CSW 较大时。
