This study aimed to describe the effectiveness and stability of implantable collamer lens (ICL) rotation in reducing high postoperative vault.
This study was conducted in the Peking Union Medical College Hospital, Chinese Academy of Medical Sciences.
This is a retrospective case series.
Twenty-two eyes from 22 patients who had ICL (V4c EVO) implantation with high postoperative vault (>=750 μm) were recruited for our study. All the lenses were rotated from a horizontal to an oblique position. The vault, SSA, AOD500, AOD750, TISA500, and TISA750 at 180° and 0° were measured pre-rotation, 1-week post-rotation, and in the at-least 1-year-follow-up.
Twenty female patients and two male patients were recruited, with a mean age of 28.68 ± 6.08 years. The mean vault had declined significantly from 951.81 ± 154.26 μm pre-rotation to 772.27 ± 119.40 μm 1 week post-rotation ( < 0.001). The SSA, AOD500, AOD750, TISA500, and TISA750 at 180° and 0° pre-rotation and 1-week post-rotation were 30.40 ± 7.91° and 45.14 ± 6.75°, 32.37 ± 7.48° and 46.23 ± 6.39°, 303.27 ± 87.99 and 522.45 ± 122.16 μm, 323.81 ± 89.15 and 536.13 ± 121.66 μm, 387.95 ± 99.43 and 630.81 ± 133.59 μm, 435.68 ± 106.72 and 643.36 ± 132.82 μm, 0.109 ± 0.034 and 0.202 ± 0.053 mm, 0.123 ± 0.034 and 0.212 ± 0.051 mm, 0.194 ± 0.056 and 0.345 ± 0.083 mm, and 0.216 ± 0.055 and 0.358 ± 0.079 mm (all < 0.001). The mean vault value had changed from 747.50 ± 116.07 μm 1-week post-rotation to 586.87 ± 132.65 μm in the 1-year follow-up. However, the SSA, AOD500, AOD750, TISA500, and TISA750 at 180° and 0° had remained stable ( > 0.05).
Non-toric ICL rotation is a novel and effective technique in the treatment of high postoperative vault. Our results are more robust given the extended period of follow-up.
本研究旨在描述可植入式角膜接触镜（ICL）旋转在降低术后高拱高方面的有效性和稳定性。
本研究在中国医学科学院北京协和医院进行。
这是一项回顾性病例系列研究。
本研究纳入了22例接受ICL（V4c EVO）植入且术后拱高较高（≥750μm）的患者的22只眼睛。所有镜片均从水平位置旋转至倾斜位置。在旋转前、旋转后1周以及至少1年的随访中，测量180°和0°处的拱高、SSA、AOD500、AOD750、TISA500和TISA750。
纳入20例女性患者和2例男性患者，平均年龄为28.68±6.08岁。平均拱高从旋转前的951.81±154.26μm显著下降至旋转后1周的772.27±119.40μm（P<0.001）。旋转前和旋转后1周时，180°和0°处的SSA、AOD500、AOD750、TISA500和TISA750分别为30.40±7.91°和45.14±6.75°、32.37±7.48°和46.23±6.39°、303.27±87.99和522.45±122.16μm、323.81±89.15和536.13±121.66μm、387.95±99.43和630.81±133.59μm、435.68±106.72和643.36±132.82μm、0.109±0.034和0.202±0.053mm、0.123±0.034和0.212±0.051mm、0.194±0.056和0.345±0.083mm、0.216±0.055和0.358±0.079mm（均P<0.001）。旋转后1周时平均拱高值为747.50±116.07μm，在1年随访中变为586.87±132.65μm。然而，180°和0°处的SSA、AOD500、AOD750、TISA500和TISA750保持稳定（P>0.05）。
非散光型ICL旋转是治疗术后高拱高的一种新颖且有效的技术。鉴于随访时间延长，我们的结果更具说服力。
