What causes astigmatism to worsen

If your vision is blurred, unfocused, or fuzzy, you may have astigmatism. This common eye disorder affects the way light enters your eye.

What is astigmatism and how can it be corrected

Approximately 1 in 3 people suffers from astigmatism. While mild cases typically need no treatment, if your vision is negatively impacting your life, treatment can help.

Depending on your doctor’s assessment, there are several treatment options.

• Corrective Lenses

  Your doctor can prescribe special glasses or toric contact lenses.

  Toric contact lenses, unlike regular contact lenses, don’t have a uniform thickness. Instead, they’re formed to correct the uneven curvature of the cornea.

  With the correct fitting, toric lenses will provide the right amount of correction while fitting comfortably.

• Surgery for Astigmatism

  Your doctor may recommend eye surgery to correct your cornea's irregular curve.

  The three surgeries most often are:

  • Photorefractive keratectomy (PRK) — the cornea is reshaped using laser beams.
  • Radial keratotomy (RK) — small incisions (cuts) are made into the cornea i
