An Ode To My Retinoscope

In May 2019 the professional journal Contact Lens Spectrum published my bi-annual ‘Refractive Focus’ column, entitled ‘An Ode to my Retinoscope’.

Kids, contact lenses, dry eye and binocular vision

Only a minimal percentage of children are likely to suffer dry eye symptoms (4%) compared to 56% in adult contact lens wearers.(1) Teens may be more likely to report contact lens related dry eye than younger children,(2) and consideration should be given to any systemic medications which could exacerbate dry eye symptoms, such as acne medications and those taken for anxiety and depression.

What about the exophores?

While esophoria and myopia have a long-associated link,(1-3) exophoria must also be on our myopia management agenda. The punchline, up front – research has shown that of kids with intermittent exotropia, 50% are myopic by age 10 and 90% are myopic by age 20,(4) and we need to be extra wary if considering fitting a myopic child like this into contact lenses.

The esophoric myope and contact lenses

When it comes to contact lens corrections for young myopes, the impact of orthokeratology (OK) and multifocal soft contact lenses (MFSCL) on binocular vision is pertinent to visual comfort and understanding mechanisms of myopia progression and control.

Specs to contacts – what happens to BV?

Changing a myope from spectacle to contact lens wear can alter their binocular vision (BV) function. The myope reading through their spectacles experiences base-in prism at near, as demonstrated in the image above, which moves the image further away and decreases vergence demand.

Which option to slow myopia? New Clinical Management Infographic

We’re excited to release our new clear, concise and clinically relevant infographic Which option to slow myopia?to help you with what we have learnt is the main practitioner need in myopia management, and the most popular discussion topic in the Myopia Profile Facebook group – guidance in selecting the right treatment for your patient. A world first, evidence based decision making tool.

Axial length measurement – a clinical necessity?

Most eye care practitioners don’t routinely measure axial length in clinical practice, mainly due to lack of access to the instrumentation and its expense. This is not the only reason, though, that axial length (AXL) measurement is a bit of a problematic measure for gauging myopia management success in a clinical setting.

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.
