To assess axis alignment and stability of the Toric Implantable Collamer Lens (TICL; STAAR Surgical Co) over time.
Thirty-five consecutive eyes of 19 patients received the TICL for treatment of myopic astigmatism. Manifest refraction spherical equivalent (MRSE) and manifest refractive cylinder were measured preoperatively and at 3 months postoperatively. The axis alignment of the TICL was measured using the internal OPD map obtained with the OPD-Scan II (NIDEK Co Ltd).
Mean refractive cylinder was reduced from 2.80+/-1.45 diopters (D) preoperatively to 0.63+/-0.75 D at 3 months postoperatively; MRSE was -7.61+/-4.02 D preoperatively and -0.14+/-0.38 D at 3 months. Mean absolute value of the measured axis misalignment from baseline (day 1) to 1 month was 2.90+/-2.11 degrees and from 1 month to 3 months was 4.6+/-11.2 degrees. Mean absolute value of the measured changes in axis misalignment from baseline to 3 months was 2.68+/-2.11 degrees (after excluding one eye that required repositioning due to TICL rotation). At 3 months postoperatively, 96.8% (30/31) eyes had <or=8 degrees and 90.3% (28/31) had <or=5 degrees of axis misalignment.
The TICL showed minimal axis misalignment after implantation and remained stable 3 months postoperatively.
评估有晶体眼散光型人工晶状体（TICL；STAAR Surgical公司）随时间推移的轴位对准情况和稳定性。
19例患者的35只连续眼睛接受了TICL植入术以治疗近视散光。术前及术后3个月测量了显验光球镜等效度（MRSE）和显验光柱镜度数。使用OPD-Scan II（尼德克公司）获得的内部OPD图测量TICL的轴位对准情况。
平均柱镜度数从术前的2.80±1.45屈光度（D）降至术后3个月的0.63±0.75 D；MRSE术前为-7.61±4.02 D，术后3个月为-0.14±0.38 D。从基线（第1天）到1个月测量的轴位偏差平均绝对值为2.90±2.11度，从1个月到3个月为4.6±11.2度。从基线到3个月测量的轴位偏差变化平均绝对值为2.68±2.11度（排除一只因TICL旋转需要重新定位的眼睛后）。术后3个月，96.8%（30/31）的眼睛轴位偏差≤8度，90.3%（28/31）的眼睛轴位偏差≤5度。
TICL植入后轴位偏差最小，术后3个月保持稳定。
