简介：波前像差引导的准分子激光角膜屈光性手术的出现,使个体化切削成为可能,通过矫正人眼生理系统的高阶像差,人们期望获得超常视力及对比敏感度.但由于像差会受到衍射和散射影响,同时还会随时间、泪膜厚度、瞳孔大小以及调节的变化而波动,从而影响得到无像差的视网膜成像.无像差的视网膜成像还要受到视网膜采样以及大脑神经系统识别等因素的影响.因此,个体化切削不一定能产生超常视力.

简介：眩晕是指患者感受周围环境或自身运动时产生的运动幻觉。眩晕症是最常见的临床综合征之一。Neuhauser报道眩晕症的患病率约为4．9％，发病率约为1．4％，而周围性眩晕是眩晕症的重要组成部分，约占眩晕门诊中的20．5％。引起眩晕的疾病种类很多，不同疾病引起眩晕的原因是不一样的。按照病变部位的不同，眩晕可以分为周围性眩晕和中枢性眩晕两大类。
