Ortho-K: overnight lenses that reshape the cornea

Part 04 · 01
The ortho-K lens flattens the corneal centre overnight and creates a steeper ring that adds peripheral myopic defocus.

    Reshapes the front of the eye

    Flatter centre for clear vision, a steeper ring for myopia control.

    Works around the clock

    No daytime wear to remember.

Newer custom designs for mild myopia

Part 04 · 02
A standard design leaves the plus-power ring outside the pupil in low myopia; a custom small zone pulls it inside the pupil.
Fig 4.2Standard vs custom small zone
  1. 01

    Mild myopia used to be the weak spot

    With standard designs, the helpful ring sat outside the pupil.

  2. 02

    Smaller treatment zones fix this

    The ring moves inward, where it can do its job.

  3. 03

    Now a real option from about −0.75 D

    We tailor the design to your child’s eye.

Myopia control glasses and soft lenses

Part 04 · 03
Defocus lenslet spectacle lenses have a clear centre with plus lenslets; contrast-reducing lenses use tiny dots.
