Overcorrection is a significant complication following radial keratotomy (RK). This study using human cadaver eyes demonstrates that the use of interrupted sutures placed across radial incisions coincident with a 7-mm optical zone mark can induce a wide range of central corneal steepening and can therefore correct varying amounts of hyperopia following RK. A case presentation confirms the effectiveness of using interrupted sutures to steepen the cornea following RK, but it also shows that significant regression of the effect must be considered at the time of suture placement. Since placement of interrupted corneal sutures is a routine procedure, it is a very convenient technique for treating overcorrection following RK.
过矫是放射状角膜切开术（RK）后的一种重要并发症。这项使用人类尸体眼睛的研究表明，在与7毫米光学区标记重合的放射状切口上放置间断缝线，可导致中央角膜大范围变陡，因此可矫正RK术后不同程度的远视。一个病例报告证实了RK术后使用间断缝线使角膜变陡的有效性，但也表明在放置缝线时必须考虑到效果的显著消退。由于放置角膜间断缝线是一种常规操作，所以它是治疗RK术后过矫的一种非常方便的技术。
