目的：探讨先天性上睑下垂矫正术后患者眼球散光的变化规律以及上睑下垂严重程度对散光的影响。方法回顾性分析行重度先天性上睑下垂矫正术的患者29例（30眼）术前及术后3~6个月眼球散光的变化。根据术前提上睑肌肌力的大小将患者分为两组（肌力≥3mm组和肌力＜3mm组）。结果先天性上睑下垂术后，患眼术前眼球总散光量为（1.78±1.02）D，术后为（1.49±0.84）D，术后散光量平均下降0.29D，与术前比较具有统计学差异（P＜0.05）。73.0%（22/30）的患眼散光轴向发生变化，但无统计学差异（P＞0.05）。健眼眼球总散光量术前为（0.56±0.54）D，术后为（0.49±0.48）D，散光量平均下降0.07D，与术前比较无统计学差异（P＞0.05），68.0%（17/25）健眼轴向发生变化，但无统计学差异（P＞0.05）。术后提上睑肌肌力≥3mm组患眼的散光量改变为（0.56±0.57） D，提上睑肌肌力＜3mm组的散光量改变为（0.11±0.45）D，两组间比较具有统计学差异（P＜0.05）。结论先天性上睑下垂矫正术后眼球散光量较术前显著下降，但散光性质无明显改变。术后散光量的变化与术前提上睑肌肌力的大小相关。

Objective To assess the astigmatism changes after surgery for congenital ptosis. Methods The data of 29 severe congenital ptosis patients(30 eyes) who underwent surgical correction were reviewed. The preoperative and postoperative astigmatism were analyzed. The patients were divided into two groups (levator force≥3mm and levator force<3mm) depending on the levator force before surgery. Results The mean astigmatism in operated eye was (1.78 ±1.02)D preoperatively and (1.49±0.84)D postoperatively. The mean change of astigmatism after surgery was 0.29D (P<0.05). The astigmatic axis had no significant change (P>0.05). The mean astigmatism in healthy eye was (0.56±0.54)D preoperatively and (0.49±0.48)D postop-eratively. The mean change of astigmatism was 0.07D(P>0.05). The astigmatic axis was no significantly changed(P>0.05). The astigmatic changes were (0.56±0.57)D in patients with levator force≥3mm and (0.11±0.45)D in those with levator force<3mm (P<0.05). Conclusion Astigmatism was significantly reduced after surgical correction in congenital ptosis patients. The changes of astigmatism are associated with the levator force before surgery.
