Kids, contact lenses, dry eye and binocular vision

Kids and dry eye 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 …

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. Oliver’s story Oliver, age 10, was referred with a history of fast, recent myopia progression. His mother was R&L -7.00 and he was …

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. Looking away from the optical centre of the lens (while keeping the vertex distance constant) also reduces …

Eight Myopia Mysteries (plus eight more!)

This open-access continuing education article I authored was published in Australian professional journal Mivision in December 2018. It describes that while there’s a lot we know about myopia control – the imperative to reduce lifelong risk of vision impairment; that numerous options are available; and that the sooner we start the better – it is imperative for the clinician to …

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 …

Contact lens safety in kids

There is no doubt that the best first choice for myopia control is a contact lens option, which both corrects ametropia and shows reliable myopia control efficacy. One of the key barriers to pediatric contact lens wear is concern about safety, however, for both practitioners and parents. Mark Bullimore1 recently published a meta-analysis of pediatric soft contact lens studies (SCL) …

Which multifocal soft lens? Efficacy and function

In an earlier post on refraction and safety with multifocal soft lenses, I discussed how colleagues often as this question – if you’re fortunate to have access to multiple multifocal, dual focus or myopia controlling contact lens designs, which is best? In Part 1 I discussed considering refraction and safety, and in this second part I’ll discuss how these lenses compare based …

Which multifocal soft lens? Refraction and safety

I was lecturing recently at the Southern Regional Congress, Australia’s largest optometry conference, run annually in Melbourne. I’d finished my myopia management lecture with a little time to spare for questions, and a colleague asked “when you’re talking about using multifocal soft contact lenses, which designs do you mean? Are you referring to [Coopervision’s] Misight, or the distance centred Biofinity …
