Standard concentric arcuate transverse corneal relaxing incisions flatten the meridian incised and steepen the meridian 90 degrees away, a phenomenon designated "coupling". We have demonstrated a new method of reducing the steep corneal curvature without inducing coupling, by utilizing both transverse and radial components of an inverse arcuate incision. This technique has been found useful in cases of myopic astigmatism because it reduces the myopic spherical equivalent, which is left unchanged by standard arcuate incisions, without having to place radial incisions.
标准的同心弧形横向角膜松解切口会使切开的子午线变平，而与之呈90度的子午线变陡，这一现象被称为“耦合”。我们已经证明了一种新的方法，即通过利用反向弧形切口的横向和径向部分来降低陡峭的角膜曲率，而不引起耦合。这项技术已被发现在近视散光病例中有用，因为它降低了近视等效球镜度，而标准弧形切口对此无影响，且无需进行放射状切口。
