PURPOSE
To evaluate the magnitude of IOL transversal shift (ITS) after phacoemulsification and to analyse the factors contributing to IOL decentration and ITS.
METHODS
94 consecutive patients who underwent cataract surgery and IOL implantation was enrolled. Each patient underwent anterior segment optical coherence tomography with CASIA 2 (Tomey, Nagoya, Japan) to assess crystalline lens decentration, thickness and diameter seven days preoperatively and at one and sixty days postoperatively. Univariate and multivariate linear regression analysis were performed to evaluate the determinants of ITS and final decentration.
RESULTS
The preoperative crystalline lens diameter was associated with the ITS and with the IOL final decentration. A positive association between the final IOL decentration and the first post-surgical day decentration was found (p < 0.0001).
CONCLUSION
Greater crystalline lens diameter was associated with greater decentration and with greater ITS. Day-one IOL decentration seems to be the main determinant of final IOL decentration.
目的
评估白内障超声乳化术后人工晶状体横向移位（ITS）的幅度，并分析导致人工晶状体偏心和 ITS 的因素。
方法
本研究纳入了 94 例连续接受白内障手术和人工晶状体植入术的患者。每位患者均接受了前节光学相干断层扫描（CASIA 2，Tomey，日本名古屋），以评估术前 7 天、术后 1 天和 60 天晶状体偏心、厚度和直径。采用单因素和多因素线性回归分析评估 ITS 和最终偏心的决定因素。
结果
术前晶状体直径与 ITS 和人工晶状体最终偏心有关。术后第 1 天的最终人工晶状体偏心与术后第 1 天的偏心呈正相关（p<0.0001）。
结论
更大的晶状体直径与更大的偏心和更大的 ITS 有关。第 1 天的人工晶状体偏心似乎是最终人工晶状体偏心的主要决定因素。
