Contact lenses for kids – paediatric, parent and practitioner psychology

When selecting an optical treatment for myopia management, contact lens options appear to be the most consistent, with OrthoK and multifocal soft contact lenses offering around a 50% efficacy for controlling refractive and axial change in myopia.1 And it’s not just the important benefit of modifying lifelong risk of vision impairment through successful myopia control which should be top of mind – contact lens wear for myopic children can offer significant immediate benefits to their self-perception and satisfaction with vision correction.

Contact lens safety in kids

A key barrier to contact lens wear in children is parental and practitioner concern about safety. The research indicates, though, that children may be the safest contact lens wearers – here we describe the statistics and how to approach clinical communication.

Myopia management message part 2 – efficacy

Let’s cut to the chase – until further notice, you can consider low dose (0.05%) atropine, soft multifocal CL’s and OrthoK as all quite similar in terms of their myopia control efficacy, being around 50% on average. A network meta-analysis of sixteen different interventions studied for myopia control showed these options to all have similar efficacy when their refractive and axial length outcomes were put on a level playing field.

Myopia management message part 1 – expectations

We have a convincing evidence base for several optical, one pharmacological and visual environment solutions to reduce the progression of childhood myopia, but nothing guarantees 100% efficacy. Because of this, even in when under a successful myopia management strategy, a child’s myopia may still progress.

Higher IOP dioptres means more risk of pathology and vision impairment, but it’s not guaranteed for an individual, Read more here…

The ‘why’ of myopia control

It is commonly understood that myopia prevalence is growing globally. By 2050, it is predicted that half of the world’s population – five billion people – will be myopic, with nearly one billion at risk of myopia related ocular pathology. The late Brien Holden was a champion of ensuring myopia is placed on the world health agenda – high myopia is strongly linked to higher risk of cataract, retinal detachment and myopic maculopathy, and increasing rates of vision impairment and blindness due to the latter are already evident in Asian countries.

Clinical Myopia Management (Lecture)

This one hour lecture, delivered to final year QUT optometry students in August 2017, covers the ‘why’ of myopia control.

Prescribing adds for near esophoria

From a myopia control point of view, esophoria and accommodative lag are the key clinical red flags in assessing your patient’s visual efficiency, and thankfully both will usually respond positively to a near addition.

Assessing near phoria

Kate describes near heterophoria to her patients as where their eyes aim in space – the posture of their vergence system – and esophoria is our key enemy in the myopia control battle.
