Astigmatism: Understanding and correcting this visual disorder
What is astigmatism?
Do you see letters that appear to stretch, lights that cast halos, or do you experience eye strain after prolonged reading? These signs may indicate astigmatism, a visual defect that affects the sharpness of images, regardless of distance.
Astigmatism results from an irregularity in the cornea, which takes on an oval shape rather than a spherical one. This distortion prevents light rays from focusing correctly on the retina, causing blurred and sometimes distorted vision.
Symptoms of astigmatism
- Blurred vision and poorly defined contours of objects, both near and far.
- Feeling that letters overlap or "smear."
- Appearance of halos around light sources.
- Eye strain and headaches after prolonged exertion.
Correction of astigmatism through refractive surgery
Refractive surgery offers an effective solution by reshaping the cornea to give it a more uniform shape. This improves image focus and restores clear vision.
How does the procedure work? The operation targets irregular areas of the cornea to even out its curvature. The treatment is personalized to precisely correct the deformities responsible for the visual impairment.
Guided corneal topography generates a high-resolution map of the corneal surface. Transmitted to the laser, this map serves as the basis for personalized treatment of astigmatism, optimizing the precision of the procedure and the quality of the visual correction.
Correction techniques
- LASIK : The gold standard solution for mild to moderate astigmatism.
- PKR : Alternative for thin corneas or patients with high-risk activities.
- SMILE: Suitable for patients with myopia and astigmatism, with rapid recovery.
FAQ - ASTIGMATISM
It can occur on its own, but is often combined with nearsightedness or farsightedness.
No, it is performed under local anesthesia using eye drops. You may experience slight discomfort during the first few days.
- LASIK and SMILE: Improved vision the very next day.
- PKR: It takes a few days to adjust.
Yes, but the natural evolution of vision may justify a long-term adjustment.
No, it is considered cosmetic surgery, but some health insurance companies offer partial reimbursement.
A preliminary consultation with an expert is essential to determine the most suitable solution.
