Small treatment zones for low myopia
Moving the myopia control ring inside the pupil.
Where the myopia control effect comes from
Part 04 · 01- 01
Clear centre, steeper ring
Ortho-K flattens the centre for clear vision and creates a steeper ring around it.
- 02
The ring signals “slow down”
Light passing through the ring focuses in front of the retina, which signals the eye to slow its growth.
- 03
It only works inside the pupil
If the ring sits outside the pupil, that light never reaches the retina.
The low myopia problem, and the fix
Part 04 · 02Low prescriptions, wide zones
With standard designs, low myopia leaves a wide clear zone and a weak ring, often outside the pupil.
A smaller treatment zone
A smaller back optic zone pulls the ring inward, where it can do its job.
Now an option from about −0.75 D
We tailor the zone size to your child’s prescription and pupil size.
What to expect
Part 04 · 03Stronger myopia control
Bringing the ring into the pupil gives the treatment more to work with in low myopia.
Possible night halos
A smaller zone can mean more noticeable halos in dim light; most children adapt.
Monitored by eye length
We track axial length to confirm the eye’s growth is slowing.
In summary
Part 04- 01The myopia control ring only works when it sits inside the pupil.
- 02Smaller treatment zones move it inward for low myopia.
- 03We measure eye length to check it’s working.
Book an ortho-K assessment.
We map your cornea first, then design the lens around it.
