MYOPIA CONTROL EXPERT

The concept

Accelerated orthokeratology or Corneal Modelling Correction is a reversible and non-invasive technique that compensates for optical defects using lenses worn at night to achieve clear, uncorrected vision during the day.

In recent years, this technique has benefited from considerable innovations, both in terms of the lens designs and in terms of the materials. It is considered an effective solution for slowing the progression of myopia, among other things.

What’s special about Ortho K

Correction of myopia and slowing of its progression

For children and adolescents:

- Controls the progression of myopia
- Lenses are worn in a controlled and safe environment (the home)
- The wearer can take part in any kind of sporting activity with total freedom

For adults:

- New-found freedom and natural vision
- Superior wearing comfort compared to day-wear lenses
- No dry eyes
- Improves depth of field
