角膜高度散光外伤性白内障的手术矫正

Surgery Correction Of Traumatic Cataract With Corneal Astigmatism

目的 :观察利用手术性散光矫正术前的角膜高度散光外伤性白内障的疗效。方法 :6 3例 ( 6 3眼 )伴角膜瘢痕高度散光的外伤性白内障 ,在角膜地形图检查指导下 ,选择屈率低的径线 ,切口长 5 5～6 0mm ,角膜缘后 0 5～ 1mm的切线切口。切口加压缝合。结果 :平均散光 :术前为 3 75± 0 6 2D。术后 1周 0 88± 0 34D ,1月 0 94± 0 2 7D ,3月 0 96± 0 2 4D。 1月后矫正视力≥ 0 5者占 85 7%。结论 :本方法明显降低术前角膜散光 ,术后视力恢复理想。

Objective:To investigate the efficacy of cataract extraction and IOL implantation on the correction of corneal astigmatism in traumatic cataract. Methods:63 eyes of 63 cases of traumatic cataract with corneal astigmatism were treated with cataract extraction and IOL implantation under the instruction of corneal topography.The mean preoperative astigmatism was 3.75±0.62D.The incision 1 mm to limbus with 5.5～6.0 mm wide was performed in the direction of low refractive power,and the properation corneal astigmatism was corrected by incision suture. Results:Postoperative astigmatism reduced significantly compared with preoperative astigmatism(P<0.01).The corrected visual acuity was 0.5 or better in 85.7% after 3 months Follow up. Conclusion:Traumatic corneal astigmatism can be corrected with cataract surgery.
