New advancements in optical technology have allowed the creation of a new type of contact lens for the correction of astigmatism called “Duette”. Duette lenses, a product from Synergeyes, combines the comfort of a soft lens with the superior vision of a rigid lens. The result is all day comfort and ”high-definition” visual clarity for nearsightedness, farsightedness, and astigmatism. (more…)
Blur due to Irregular Cornea
Refractive surgery, corneal transplants, infections and corneal syndromes like Keratoconus are among the many potential causes for irregular corneas. An irregular cornea results in symptoms of blur and distortion that glasses and most contact lenses are unable to correct. Visual symptoms from an irregular cornea are constant, but often worsen in dim light when the pupil is more dilated.

Astigmatism is the most common refractive condition. It’s different from being nearsighted or farsighted. Astigmatism means that light entering the eye is not focusing in one place. Instead light is being scattered and the result is blurred vision.
Most often, astigmatism results from misshapenness on the front surface of the eye (the cornea). Instead of the cornea being spherical like the side of a basketball, it’s shaped more like the side of a football, flatter in one area and steeper in the other areas.
At Iowa EyeCare we correct astigmatism using glasses, contact lenses, or even LASIK surgery. If you aren’t seeing as well as you think you should, it just might be astigmatism that’s causing a problem. Schedule an appointment today in either of our Marion, Robins or Cedar Rapids, Iowa, locations to find our which treatment options are right for you.
