Astigmatism Treatment from Your Lubbock, TX Optometrist

People are often surprised to learn that as many as 30-percent of Americans have astigmatism.  A visit to our Ginter Eyecare Center in Lubbock provides patients with state-of-the-art eye exams for detecting this condition and other vision issues treated by our dedicated team of optometrists.

Overview of Astigmatism

Ideally, an eye is perfectly round and able to focus light evenly and with clarity.  However, the cornea, a cover for the eye’s pupil and iris, is actually warped in patients with astigmatism.  As a result, light cannot properly focus on the retina at the back of the eye.  Patients might develop headaches and other discomfort and experience blurred vision.

This disorder has no known cause.  It is usually present at birth and is sometimes hereditary.  Many people receive a diagnosis after a school vision test.

Often this condition occurs with other refractive issues such as nearsightedness and farsightedness.  Optometrists diagnose the disorder after a comprehensive eye exam that might include several types of tests:

  • Visual acuity exams evaluate reading numbers on a distance chart.
  • Keratometry measures curvature of a cornea.
  • Topography creates a detailed corneal contour map.
  • Refraction reveals the corrective lenses that provide clear vision.

Treatment Options for Astigmatism

Our doctors of optometry offer a variety of treatment options using corrective lenses.  Prescription lenses in eyeglasses cause light to bend into the eye correctly despite the cornea’s uneven shape.  They can also correct additional refractive issues such as farsightedness or nearsightedness. 

Astigmatic patients have a wide choice of styles and types of contact lenses.  Among them are special toric soft lenses, extended wear contacts, gas permeable lenses, and bifocal contacts.

Another option is orthokeratology, which requires wearing a series of rigid contacts to reshape the cornea.  Since vision correction is only temporary, patients must continue to wear prescribed lenses to maintain it.

Eye doctors evaluate patients seeking to reduce their dependence on glasses or contacts to determine whether they are candidates for refractive surgery:

  • LASIK involves making a thin corneal flap that is also hinged.  Using an excimer laser, the surgeon revises the cornea’s shape, then replaces the flap.
  • LASEK is a similar procedure but relies on loosening the cornea's protective cover using alcohol rather than making a flap.
  • PRK is similar to a LASEK procedure.  However, the surgeon actually removes the cover of the cornea, which eventually regrows. 
  • Epi-LASIK uses a special blade to separate a thin sheet of the cornea’s protective cover.  After reshaping the cornea with a laser, the surgeon repositions the cover.
