We present a case of toric implantable collamer lens (TICL) spontaneous rotation in a patient with myopic astigmatism. A 23-year-old female underwent TICL implantation. Preoperative uncorrected visual acuity (UCVA) was 20/800 and 20/1200, respectively, with -7.75 -4.25 × 0° and -8.25 -5.25 × 180°. The left eye achieved an UCVA of 20/30. After 3 months of successful implantation of TICL in the left eye, the patient presented with a sudden decrease in visual acuity in the left eye. UCVA was 20/100 with a refraction of +2.50 -4.50 × 165°. We observed the toric marks with a 30° rotation from the original position and decided to reposition the TICL, obtaining a final UCVA of 20/25, which remained stable at 6 months' follow-up. TICL can present a considerable rotation that compromises visual acuity. The relocation of TICL is a safe and effective procedure to recover visual acuity due to significant spontaneous TICL rotation.
我们报告一例近视散光患者的有晶体眼散光型人工晶状体（TICL）自发旋转病例。一名23岁女性接受了TICL植入手术。术前裸眼视力（UCVA）分别为20/800和20/1200，散光度数分别为-7.75 -4.25×0°和-8.25 -5.25×180°。左眼术后UCVA达到20/30。左眼成功植入TICL 3个月后，患者左眼视力突然下降。UCVA为20/100，验光结果为+2.50 -4.50×165°。我们观察到有晶体眼散光型人工晶状体标记相对于初始位置旋转了30°，于是决定重新调整TICL位置，最终UCVA达到20/25，在6个月的随访中保持稳定。有晶体眼散光型人工晶状体可能会出现明显旋转，从而影响视力。对于因有晶体眼散光型人工晶状体显著自发旋转而导致视力下降的情况，重新调整其位置是一种安全有效的恢复视力的方法。
