At present Orthokeratology & Paragon
CRT™ is only suitable for the correction of myopia
(short-sightedness) of up to -6.00D, and also for the
reduction of astigmatism of up to 1.75DC.
It is not yet suitable for the correction of hypermetropia
(long-sightedness).
Children
It is extremely good for the correction of children,
as contact lenses and spectacles are then not required
for sports and outdoor activities.
Children & Myopia Control
Research has just been published that has shown a 50%
reduction in the development of short sightedness in
children using Orthokeratology lenses. To view
