Granular Dystrophy - A hereditary eye condition where pale gray granules appear in the stromal layer of the cornea, like little crumbs. It’s usually detected by the time a person is about 20. By age 40 or so, vision will be increasingly impaired as those granules, or lesions, expand, increase in number, coalesce, and penetrate more deeply into the stroma. It can be treated in earlier stages with an excimer laser, or in other ways that remove the granules, and later on by a corneal transplant.
Halos - A visual condition where a light source appears with a blurry circle of light around it, rather than having visible edges. It can be a complication of refractive surgery, and can also occur naturally. It makes night vision difficult.
Haze - Clouding of the cornea. It can be caused by inflammation, too much moisture, scar tissue, or some kind of foreign substance as from a medication.
Higher Order Aberration - The lower order aberrations are familiar names to most of us: myopia, hyperopia, and astigmatism, and they’re refractive errors. The higher order aberrations are irregularities of the eye that are not refractive. Sixty-four have been detected and measured so far, using wavefront technology. They’re not treatable with traditional LASIK procedures, glasses or contact lenses, but can be diagnosed and treated by wavefront-guided LASIK. Any given eye usually has more than one, which interact, producing symptoms. That means the aberrations can’t necessarily be established based on symptoms. They come into play at night, or in low lighting conditions. Some examples are:
Spherical Aberration (irregularity in the eyeball’s shape), which creates halos around points of light
Coma, which makes points of light look like comets with blurry tail-like smudges
Loss of contrast
Double vision
Hyperopia - (hi-pur-OH-pee-uh) Farsightedness. It’s one of the lower order aberrations (along with myopia and astigmatism), and is correctible by glasses, contact lenses, and LASIK procedures. The higher order aberrations are more subtle and are non-refractive errors of the eye.
