PURPOSE
To determine the effect of successful pterygium surgery on astigmatism and other corneal topographic indices.
METHODS
Preoperative and postoperative refraction and corneal-topography analysis were performed on 16 consecutive eyes of 12 patients who underwent successful pterygium surgery, with statistical comparison of the pre- and postoperative visual acuity, refractive astigmatism, topographic astigmatism, Surface-Regularity Index, and Surface-Asymmetry Index.
RESULTS
Successful pterygium surgery caused statistically significant improvements in visual acuity, refractive and topographic astigmatism, the Surface-Regularity Index, and the surface asymmetry index.
CONCLUSION
Corneal-topography analysis is an important component of the evaluation of patients with pterygium, revealing significant abnormalities that are improved by successful removal of the pterygium.
目的
确定成功的翼状胬肉手术对散光及其他角膜地形图指标的影响。
方法
对12例接受成功翼状胬肉手术患者的16只连续眼睛进行术前和术后验光及角膜地形图分析，并对术前和术后的视力、屈光性散光、地形性散光、表面规则性指数和表面不对称指数进行统计学比较。
结果
成功的翼状胬肉手术在视力、屈光性和地形性散光、表面规则性指数及表面不对称指数方面引起了具有统计学意义的改善。
结论
角膜地形图分析是翼状胬肉患者评估的重要组成部分，揭示了通过成功切除翼状胬肉而改善的显著异常情况。
