How to correct astigmatism?

Astigmatism is a visual disturbance shared by 75% of the population, of which 30% wear correction

This pathology is caused by irregularity of the curvature of the cornea and the lens. A blurred image is formed on the retina, which prevents normal vision. In this article, the Dr. Stéphanie Zwillinger’s COP9 team will show you the various methods to correct astigmatism.

Using cylindrical corrective lenses

to correct astigmatism

Using optical gear in order to correct astigmatism is a necessity. Wearing cylindrical corrective lenses is one of the solutions recommended in ophthalmology. Daily use is mandatory to get the correct visual acuity.

Degree of correction is assessed by your ophthalmologist during your appointment. Here at COP9, we give you your medical prescription after a set of examinations performed by our orthoptist, and a check-up executed by our eye-surgeon, Dr. Stéphanie Zwillinger.

cylindrical lenses to correct astigmatism

Did you know?

Lenses used to correct astigmatism are called cylindrical because of their shape! Axis is oriented based on the prescribed indications in order to regulate this refractive error.

Finally, it’s useful to know that every patient touched by astigmatism be subject to myopia or hypermetropia. With a recent and adapted prescription, these cylindrical lenses can also correct these other visual disturbances.

Anti-fatigue lenses

to correct astigmatism

Anti-fatigue lenses can be used to correct low and isolated type astigmatism. This correction won’t get you a better sight, but can ease some symptoms, such as:

  • headaches
  • ocular fatigue

These lenses are prescribed to patients who need to rest their eyes while reading, driving, or in front of a screen.

However, if the patient suffered from astigmatism and myopia/hypermetropia/presbyopia or a medium to high astigmatism, wearing anti-fatigue lenses won’t be enough of a match against these visual disturbances.

Another optical gear, eye-lenses can also be a solution for people with astigmatism who wish not to wear glasses (anymore).

To learn more about this type of optical correction, we offer you a selection of articles addressing the topic:

to correct astigmatism

Patients over 20 years of age, whose astigmatism has been stable for at least 3 years can consider eye surgery with their eye-surgeon. A pre-procedure check-up is then performed by the specialist to ensure that surgery is the best operative method. Factors such as the thickness and regularity of the cornea are checked thanks to corneal topography.

Laser procedure, depending on the specialist advice may be:

  • LASIK;
  • ReLEx SMILE technique;
  • classic PKR or transepithelial (t-)PKR.

To correct this sight disturbance using surgery, your ophthalmologist will choose one type over another based on the size of your cornea and the severity of your astigmatism (high or medium). Laser surgery is performed under local anesthesia, by applying eye-drops.

If you’re not eligible for laser eye surgery and suffer from a day-to-day disabling astigmatism, intraocular implants (IOLs) can exceptionally be considered. However, the placement of an implant carries higher risks than a laser procedure.

Finally, if your ophthalmologist finds even the slightest keratoconus in his or her pre-procedure check-up, surgery is off the table and contraindicated.
