在眼镜的典型眼科检查中,验光师将通过询问眼图的视图更清晰地通过称为Phoropter的设备来测量您的视觉。这称为主观折射,准确到患者可以区分两种选择的程度。

这种考试的一个问题是放置在患者面前的镜片仅包括两种类型:球形和圆柱形。当处方眼镜时,这是足够的,因为玻璃只能给出相同的两个形状并正确求视力。我们的愿景除了球形和圆柱形误差之外还有许多像差。我们有差距被称为“更高的差距”, 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 更高的差距 are a possibility. For many people, these 更高的差距 are very minor. There are some people who wavefront LASIK provides vision that is superior to standard LASIK or a glasses correction. Wavefront LASIK has been shown to reduce the possibility of glare or halos which can occur following LASIK surgery.

Lasik在大多数情况下重塑角膜以提供出色的愿景。 Laservue提供LASIK咨询 旧金山 海湾地区, 圣荷西, 和 圣罗莎.
