We performed Troutman's technique of corneal wedge resection in 6 patients who had substantial astigmatism after penetrating corneal grafts. The astigmatism was reduced by 5 to over 15 dioptres, and was stable for up to 36 months. The visual acuity was considerably improved in 5 of the 6 cases. However we could not neither predict the amount of correction nor the axis of the residual astigmatism with this technique. We stress the importance of using a keratometer when performing a penetrating corneal graft.
我们对6例穿透性角膜移植术后存在明显散光的患者实施了特劳特曼角膜楔形切除术。散光度数降低了5至超过15屈光度，且在长达36个月的时间内保持稳定。6例患者中有5例视力得到显著改善。然而，使用该技术我们既无法预测矫正量，也无法预测残余散光的轴向。我们强调在进行穿透性角膜移植时使用角膜曲率计的重要性。
