What Conditions does Z-LASIK Treat?
Myopia, or “nearsightedness” is the most common reason for needing distance glasses.
Myopia occurs when the eye grows too long for the natural curvature of the cornea (clear window at the front of the eye). In myopic eyes, light rays focus in front of the retina.
Hyperopia, or “farsightedness” means the eye is too short for the natural curvature of the cornea (clear window at the front of the eye).
In hyperopic eyes, light rays are focussed behind the retina.
Astigmatism means that the eye is shaped like an egg, so light rays do not come into clear focus on the retina.
Astigmatism can occur alone, or in combination with myopia and hyperopia.
