NightFlex and NightFlex Relax
Orthokeratology when carried out with a responsible approach, regular check-ups and appropriate patient selection, is reliable, effective, reversible, and profitable method of myopia correction. This, in turn, may result in high patient satisfaction accompanied by long lasting loyalty.
Orthokeratology lenses are worn by night to reshape the cornea geometry during a sleep in such a way that during a day sharp vision is ensured without any other vision aid.
Recent studies have revealed that orthokeratology may slow down the myopia progression. To enhance its effectivenss, SwissLens has made a calculator thanks to which OrthoK design for myopic kids can be now supported with the Relax system.
