本篇報告壹病例,經全層角膜移植後,因有11D的反常散光(Against-the-rule Astigmatism),並且同時合併有白內障,筆者利用白內障手術當中,大面積的輪部緊密壓迫性縫合(Limbal Compression Suture),加上角膜鬆弛性切開術(Corneal Relaxing Incision)及角膜壓迫性縫合(Corneal Compression Suture)來矯正移植術後的高度散光。經過兩年的追踪治療後,減少了10D的散光,效果相當良好。
With the advent of microsurgical technique, penetrating keratoplasty has become highly successful. But post-keratoplasty astigmatism is still a troublesome problem. At the same time, routine post-operative steroid usage will induce cataract in some patients. We report a case who received corneal transplant in 1986. The graft was clear but with 11 D against-the-rule astigmatism. He developed posterior subcapsule cataract 1 year later. We performed relaxing incision and limbal compression during cataract operation. His corneal curvature is rather satisfactory after 2 years follow up.
