角膜地形图在白内障手术切口中的作用

The Function of the Corneal Topography in Selected Cataract Surgery Incision

目的：观察根据角膜地形图选择白内障手术切口的效果。方法：以白内障术前检查，角膜曲率两垂直子午线K1和K2差值大于0．75D者，均作角膜地形图检查，然后根据角膜地形图选择最陡子午线作手术切口，观察术后视力及角膜散光情况。结果：①视力：本组病例术后7d，裸眼视力0．1-0．4，7眼占12．07％；0．5～0．842眼占72．41％；0．8以上9眼占15．52％。②术后散光：3个月后作角膜地形图检查对比，58例58眼病人，术后散光均较术前明显改善。结论：根据角膜地形图选择白内障手术切口，术后视力好，散光度降低，病人满意度提高。

Objective： To observe the effect of the cataract surgery incision which selected according to corneal topography. Method： According to before cataract surgery examine , all which the dispersion of the k1 and k2 is more than 0.75D wound be examined corneal topography ,then selected cataract surgery incision according to the most steep meridian, and observed the vision and corneal astigmatism after the cataract surge. Result：①after 7 days of the this group , the uncorrected visual acuity ： 0.1 - 0.4 in 7 eyes（ 12. 07% ） ,0.5 -0.8 in 42 eyes （72.41% ） ,upwards of 0.8 in 9 eyes（ 15.52% ）. ②the astigmatism after 3 months ：the corneal topography indicated the astigmatism, there was obvious improved in 58 eyes. Conclusion： It can be improved the visual acuity and reduced the astigmatism which cataract surgery incision done according to the corneal topography.
