Correlated study of wavefront aberrations and refractive index in myopia 近视眼波前像差与屈光参数的相关性研究
Methods The peak systolic velocity and resistive index of ophthalmic artery were measured by colour doppler and two dimensional echocadiography ( 2 DE) in 48 myopia students with glasses before and after the ocular gymnastics. 方法近视戴镜学生48人,在做理视健眼操前后,用彩色多普勒测定眼动脉的收缩期峰值速度和阻力指数。
The surface regularity index ( SRI) was positively correlated with surface asymmetry index ( SAI), and the astigmatism was positively correlated with dioptre and SAI in myopia. 角膜表面规则性指数(SRI)与角膜表面非对称性指数(SAI)呈正相关,而且近视眼的散光度与其屈光度、SAI呈正相关。
