We have had effective techniques to slow Short Sight (Myopia) progression for some years now. While extremely effective, previous strategies have relied solely on contact lens options which don’t necessarily appeal to everyone. We are very proud to be an accredited prescriber of MiYOSMART spectacle lenses by HOYA.
This award winning invention allows everyone the opportunity to control short sight progression regardless of age or concerns about contact lens wear. Coupled with our existing contact lens options we can tailor strategies to suit each individual child. MiSight is a daily disposable contact lens specifically designed to slow myopia progression. We also use multifocal soft contact lenses and orthokeratology as bespoke strategies for difficult prescriptions.
We are all born ‘Long Sighted’, meaning our eyes are slightly small; this is normal. Children of age 2 should be about +2.00. As we grow our eyes lengthen and we become less long sighted. Unfortunately, for some children, the growth doesn’t stop. The eye length moves beyond the neutral point and these people become short sighted. This is why some people may not become short sighted until their teens.
Figure 1 (below): In eyes destined to remain normally sighted the retinal image is equally focussed across the entire retina (the ‘image shell’ is represented as the red arc - Fig 1) and not simply the central macula. The macular is the portion of the retina at the centre of vision used for accurate vision such as watching TV and reading.
Figure 2: A push toward short sight is induced when the ‘image shell’ is behind the retina in the periphery (Fig 2). The patient will not notice this as the central vision is clear. The ‘peripheral defocus’ stimulates the eye to grow in an attempt to bring this imaging into focus.
Figure 3: As the eye grows it becomes short sighted (myopic) and the patient will notice blurry vision as the increased eye length pushes the macula away from the accurately focussed point.
Figure 4: Once the eye is corrected for its’central myopic blur the ‘relative peripheraldefocus’ is re-establed and with it thestimulus for further eye growth and myopicprogression.
