Am I eligible?

Are you eligible for refractive surgery?

Find out whether refractive surgery could help you become free of glasses or contact lenses!

Annecy Laser Vision, at the centre médical des Aravis, offers this questionnaire to give you an initial idea of your eligibility for refractive surgery.

Good to know: Only a full preoperative assessment can determine whether you are a suitable candidate.

Reminder of the different types of refractive surgery:

• LASIK: The most widely used technique, ideal for correcting short-sightedness, long-sightedness and astigmatism. A corneal flap is created, then the cornea is reshaped with a laser.
• PRK / TransPRK: An alternative to LASIK, particularly suited to thin corneas, sportspeople and people with dry eye. The laser reshapes the surface of the cornea.
• Phakic lens implants: Lenses implanted in the eye, in addition to the natural lens, to correct significant refractive errors.
  
  

  How to read your glasses prescription

  Your glasses prescription contains important information about your vision correction. Here are the key elements to understand:

  • OD (right eye) and OG (left eye): The prescriptions are shown separately for each eye.
  • Sphere (sph): Indicates the power of the correction for short-sightedness (negative value) or long-sightedness (positive value). The higher the number, the stronger the correction.
  • Cylinder (cyl): Indicates the power of the correction for astigmatism. If this value is present, you have astigmatism.
  • Axis: Indicates the orientation of astigmatism in degrees.
  • Addition (add): This relates to presbyopia correction. It indicates the power to add to the distance prescription for near vision.

  Example:

  OD: sph -2.00 cyl -0.75 axis 90° OS: sph -1.50

  This example shows that the right eye has myopia of -2.00 dioptres and astigmatism of -0.75 dioptres at 90°. The left eye has myopia of -1.50 dioptres.
