- The diopters of spherical equivalent corrected were highly correlated with surgical-induced HOA changes. 矫正近视的球镜当量度数多寡，和手术引起的高阶像差变化呈高度相关；
- Conclusion:The agreement between cycloplegic retinoscopic and autorefractive spherical equivalent diopter was high. 自动验光仪验光的结果比视网膜检影结果稍小一些。
- Smith (1962) considered three alternate methods to determine an equivalent diameter of graded sediment. 史密斯（1962）提出了三种不同方法以计算不均匀沙的当量直径。
- Spherical equivalent had a linear relationship with VA (P<0.01) but not with the strabismus degree (P>0.05). 视力与等效球镜度之间有直线相关关系(P<0.;01)，而斜度与等效球镜度之间无直线相关关系(P>0
