Are you eligible to surgery? 

Patient side

You must meet the following requirements

Be at least 18 years old

Not be pregnant or breasfeeding.
Have optical correction stabilized for at least 18 months.
Not have any ophthalmological contraindications (keratoconus, too thin cornea, intercurrent diseases such as cataract, proven glaucoma,...) or general diseases (especially general inflammatory diseases that can affect the cornea, such as rheumatoid arthritis), and have a correction which is accessible to the laser.
Excimer laser can be used (with LASIK technology) for myopia up to – 12 D, hyperopia up to + 6 D, and astigmatism up to 6 D, provided corneal parameters are adequate (thickness, curvature radius, etc.).
Once again, each patient is specific and your surgeon is the only person able to choose, with you, the most appropriate techniques.
