在典型的眼镜眼科检查中,验光师将通过称为“屈光检查仪”的设备来测量您的视力,方法是询问哪种视力表更清楚两种选择。这称为主观屈光,并且精确到患者可以区分这两种选择的程度。

这种检查的一个问题是放在患者面前的镜片仅由两种类型组成:球形和圆柱形。在开眼镜时,这是足够的,因为眼镜只能具有相同的两种形状并且可以矫正视力。除了球面和圆柱误差外,我们的视觉还有许多像差。我们有被称为畸变“高阶像差”, which include coma, trefoil, spherical aberration, and others. Glasses cannot correct for these aberrations. With a laser vision correction, such as LASIK, the correction of 高阶像差 are a possibility. For many people, these 高阶像差 are very minor. There are some people who wavefront LASIK provides vision that is superior to standard LASIK 要么 a glasses correction. Wavefront LASIK has been shown to reduce the possibility of glare 要么 halos which can occur following LASIK surgery.

LASIK可重塑角膜,在大多数情况下可提供出色的视力。 LaserVue在以下位置提供LASIK咨询: 旧金山 海湾地区, 圣荷西圣罗莎.
