PURPOSE
To describe the good outcome of implantable collamer lens (ICL) rotation to reduce post-operative vault.
METHODS
Retrospective analysis of case report. A 43-year-old woman had V4c EVO + myopic non-toric ICL implantation and post-operatively she presented with anisocoria and high vault. She underwent surgery to rotate the ICL 90 degrees to a vertical orientation.
RESULTS
We achieved a reduction in the vault from 1020 to 486 μm after vertical ICL rotation. Satisfactory refractive outcome and optimal vault were achieved and maintained during the period of follow-up.
CONCLUSION
Optimal ICL sizing is important as too high vault/clearance is associated with problems such as angle closure glaucoma, pupil dilatation and anisocoria and too low vault/clearance to increased risk of cataract formation. Non-toric ICL rotation can be a simple surgical technique to deal with oversized lenses thus avoiding ICL exchange.
目的
描述可植入式胶原晶状体（ICL）旋转以减少术后房高的良好效果。
方法
病例报告的回顾性分析。一名43岁女性接受了V4c EVO + 近视非散光型ICL植入术，术后出现瞳孔不等大和高房高。她接受了手术，将ICL旋转90度至垂直方向。
结果
ICL垂直旋转后，房高从1020μm降至486μm。在随访期间获得并维持了满意的屈光效果和最佳房高。
结论
合适的ICL尺寸很重要，因为过高的房高/间隙与诸如闭角型青光眼、瞳孔散大和瞳孔不等大等问题相关，而过低的房高/间隙会增加白内障形成的风险。非散光型ICL旋转可以是一种简单的手术技术，用于处理过大的晶状体，从而避免ICL置换。
