The changes of higher-order aberrations (HOAs) after bilateral lateral rectus muscle recession were evaluated. Forty eyes of 20 children were enrolled and their wavefront information was assessed until postoperative 3 months. Even though the root mean square (RMS) of total aberration was not changed, the RMS of HOA was transiently increased at postoperative 1 week and returned to baseline level after 1 month. Among individual Zernike coefficient, secondary astigmatism, quadrafoil, secondary coma, secondary trefoil, and pentafoil showed similar tendency with the RMS of HOA. However, coma, trefoil, and spherical aberration were not changed. Regarding recession amount, it did not correlate with any Zernike coefficient. In summary, our data imply that the HOAs are transiently increased after lateral rectus recession surgery. These results are in collusion with previous reports that strabismus surgery induced transient corneal astigmatism.
评估了双侧外直肌后退术后高阶像差（HOAs）的变化。纳入 20 名儿童的 40 只眼，并在术后 3 个月内评估其波前信息。尽管总像差均方根（RMS）没有变化，但术后 1 周时 HOAs 的 RMS 一过性增加，1 个月后恢复基线水平。在个别泽尼克系数中，二次散光、四叶草、二次彗差、二次三叶、和五叶显示出与 HOAs 的 RMS 相似的趋势。然而，彗差、三叶和球差没有变化。关于后退量，它与任何泽尼克系数都没有相关性。总之，我们的数据表明，外直肌后退术后 HOAs 一过性增加。这些结果与先前报道的斜视手术后引起的瞬态角膜散光一致。
