分析 6 6例准分子激光角膜屈光性手术后屈光回退患者角膜地形图曲率变化与屈光回退值的关系。结果显示角膜曲率变化与临床屈光度变化的关系 :Y =1.42 5 2X + 1.2 5 5 9,r =0 .84,P <0 .0 0 1(Y为临床屈光变化值 ,X为角膜曲率变化值 )。表明准分子激光角膜屈光性手术后屈光回退患者手术前后角膜曲率变化与屈光度变化有高度相关性 ,提示角膜地形图在准分子激光手术后的屈光变化判断中有重要意义
The relationship between corneal topography curvature and refractive regression was analyzed in 66 patients with refractive laser corneal refractive surgery. The results showed that the changes of corneal curvature and clinical diopter changes: Y = 1.42 5 2X + 1.2 5 5 9, r = 0.84, P <0 0 01 (Y is the value of clinical refractive changes, X is the curvature of the cornea value). It shows that there is a high correlation between the change of corneal curvature and the change of diopter before and after the operation in patients with refractive retrofraction after excimer laser corneal refractive surgery, suggesting that the corneal topography is of great significance in judging the refractive change after excimer laser surgery
