Corneal astigmatism can be treated optically or surgically. First, we try to manage the astigmatism with glasses or contact-lenses. If it cannot be managed successfully with optical devices, a surgical approach may be indicated. Corneal wedge resections and relaxing incisions can be effective. The wedge resection is the more difficult procedure with reasonably predictable results. In recent years corneal relaxing incision has gained popularity because it is a simple technique with fairly rapid visual rehabilitation. However, the correction result is quite unpredictable. We try to evaluate the factor that created the astigmatism. The steep and flat corneal meridian are identified with keratoscopy, and the correction is performed at the end of the corneal meridian causing the astigmatism. The technique and results are discussed.
角膜散光可以通过光学方法或手术方法进行治疗。首先，我们尝试通过眼镜或隐形眼镜来矫正散光。如果无法通过光学装置成功矫正，可能需要采取手术方法。角膜楔形切除术和松解切口可能有效。楔形切除术是难度较大的手术，但结果相对可预测。近年来，角膜松解切口越来越受欢迎，因为它是一种简单的技术，视力恢复相当快。然而，矫正结果很难预测。我们试图评估导致散光的因素。通过角膜镜检查确定角膜的陡峭和扁平子午线，并在导致散光的角膜子午线末端进行矫正。本文将讨论该技术及结果。
