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 …

Vision with Pediatric Bifocal Contact Lens Wear

Center-distance soft multifocal contact lenses have been shown to slow the progression of myopia,1-5 but practitioners around the world are concerned about the vision produced by soft multifocal contact lens wear in children. Many doctors place soft multifocal contact lenses with center-distance design on children’s eyes and measure the vision. If the child can only read 20/30 to 20/40, the …

A Novel Soft Radial Refractive Gradient (SRRG) contact lens for myopia control

Recently, I completed my PhD on myopia control with a soft Radial Refractive Gradient (RRG) design contact lens. This experimental design was primarily based on the peripheral retinal blur theory, that E. Smith developed,1 providing an incremental, progressive, refractive change from the central visual axis to peripheral retina, reaching a +2.00D add plus power at about 35 degrees of retinal …
