The change in refractive status of an eye that has undergone muscle surgery appears to be due to cornea changes. While not all patients are affected, a moderate number will show enough change in astigmatism to cause a decrease in the visual acuity from a few letters to two lines difference. These changes, more commonly an increase in with the rule astigmatism, tend to disappear in time, although in an occasional patient they may persist. Such a change is especially noted when two nonadjacent recti muscles are operated on the same eye. One advantage in operating on the fixing eye is that of allowing a surgically induced amblyopic therapy to continue into the postoperative period. A noncycloplegic or "dry" retinoscopy seems to be a quick and effective way of determining the existence, though not the amount, of such a change in the refractive status.
接受过肌肉手术的眼睛屈光状态的变化似乎是由角膜变化引起的。虽然并非所有患者都会受到影响，但有相当一部分患者会出现足够的散光变化，导致视力下降几个字母到两行的差异。这些变化，更常见的是顺规散光增加，往往会随着时间消失，尽管在个别患者中可能会持续存在。当同一只眼睛的两条不相邻直肌接受手术时，这种变化尤为明显。对注视眼进行手术的一个优点是，允许手术诱发的弱视治疗持续到术后阶段。非睫状肌麻痹或“干式”检影法似乎是一种快速有效的方法，可确定屈光状态是否存在这种变化，尽管无法确定变化的程度。
