To explore the influence of corneal higher-order aberrations (HOAs) on dynamic visual acuity (DVA) post cataract surgery.
A total of 27 patients with 45 eyes following cataract surgery were included in this study. The postoperative monocular object-moving DVA at the velocity of 20, 40, and 80 degrees per second (dps) were examined at 1 month. The total corneal HOAs were measured with Scheimpflug-based corneal topography. The correlation between postoperative DVA and HOAs was analyzed.
Significant difference was shown among DVA at different velocities ( < 0.001). The 20 dps DVA was significantly better than 40 ( < 0.001) and 80 ( < 0.001) dps DVA. No significant difference was observed between 40 and 80 dps DVA ( = 0.420). The vertical coma and the root mean square (RMS) of coma (RMS) were statistically correlated with 80 dps DVA ( < 0.05). The vertical trefoil, RMS and total RMS were statistically correlated with 40 and 80 dps DVA ( < 0.05). The spherical aberration was not significantly associated with postoperative DVA ( > 0.05 for all velocites). The multivariate linear regression model revealed that age was a significant influential factor for 20 dps DVA ( = 0.002), and RMS (4 mm) and age were significantly associated with 40 and 80 dps DVA ( ≤ 0.01).
The research demonstrated that larger corneal HOAs, especially coma and trefoil aberrations were significantly associated with worse high-speed DVA, but not spherical aberration post cataract surgery.
探讨角膜高阶像差（HOAs）对白内障手术后动态视力（DVA）的影响。
本研究纳入了27例白内障手术后的45只眼。术后1个月时，检测单眼在每秒20、40和80度（dps）速度下的物体移动DVA。使用基于Scheimpflug的角膜地形图测量角膜总高阶像差。分析术后DVA与高阶像差之间的相关性。
不同速度下的DVA之间存在显著差异（<0.001）。20 dps的DVA显著优于40（<0.001）和80（<0.001）dps的DVA。40和80 dps的DVA之间未观察到显著差异（=0.420）。垂直彗差和彗差均方根（RMS）与80 dps的DVA存在统计学相关性（<0.05）。垂直三叶草像差、RMS和总RMS与40和80 dps的DVA存在统计学相关性（<0.05）。球差与术后DVA无显著相关性（所有速度下均>0.05）。多元线性回归模型显示，年龄是20 dps DVA的显著影响因素（=0.002），RMS（4 mm）和年龄与40和80 dps的DVA显著相关（≤0.01）。
研究表明，较大的角膜高阶像差，尤其是彗差和三叶草像差与白内障手术后较差的高速DVA显著相关，但与球差无关。
