(8) Numerous approaches have been used in an effort to slow down the progression of myopia including: increased time outdoors; (9) pharmaceutical interventions; (10) bifocals and progressive spectacle lenses; (10) multifocal soft and rigid gas permeable contact lenses; (10) and orthokeratology (ortho-k) lenses.
In modern orthokeratology, most of the ortho-k lenses being fitted are of high oxygen permeability, well centered, and are supposed to yield relatively even forces to different corneal meridians.
The uses of RGPCLs vary from orthokeratology to irregular corneal vision restoration and refractive error compensation.

Several clinical trials have shown that a myopic defocus ring in the peripheral retina can slow axial growth; this may be caused by orthokeratology or spherical and multifocal soft contact lenses.
Ote has highlighted its contact lens solution designed specifically for orthokeratology and other rigid gas permeable contact lenses.
Nowadays, overnight orthokeratology is becoming more and more popular especially in the Asia-Pacific region to control the progression of myopia in young children.
The Young's modulus is an accepted biomechanical property [22] that may be used for predicting postrefractive surgery ectasia [23, 24], detecting early keratoconus [6,25], and reshaping orthokeratology [23, 26, 27].
The use of orthokeratology for myopia control has also introduced the addition of overnight wear to this cohort.
It works by manipulation of the peripheral image shell; this is similar to the effect produced by orthokeratology, which will be discussed in more detail later.
