目的探讨翼状胬肉切除术后角膜屈光力的改变。方法随机选择翼状胬肉切除患者38例,行术前、术后1周、术后1个月角膜屈光力的检测,并进行分析。结果与术前相比,术后1周角膜垂直子午线屈光力减少、水平子午线增加,散光度下降;与术后1周相比,术后1个月角膜垂直、水平子午线屈光力无明显变化,散光度无明显变化。结论翼状胬肉切除术后1周患者角膜形态趋于稳定。
Objective To investigate the changes of corneal refractive power after pterygium excision. Methods 38 patients with pterygium resection were randomly selected. The corneal refractive power was measured before operation, 1 week after operation and 1 month after operation. Results Compared with preoperative, corneal vertical meridian refractive power reduced, horizontal meridian increased, and astigmatism decreased compared with that before operation. Compared with one week after operation, corneal vertical and horizontal meridian refractive power had no significant changes, astigmatism No significant changes. Conclusion One week after pterygium resection, corneal morphology tends to be stable.
