Earlier Orthokeratology fitting for more effective myopia control

Orthokeratology Society of Oceania - Wednesday, August 16, 2017

Myopia (short-sightedness) has been recognized as a global public health concern. Clinicians, researchers and scientists are currently examining the mechanisms of myopia progression, how we may address risk factors and slow/halt these changes in the eye.

Recently, Professor Pauline Cho’s research has shown that myopia control treatment for children at a younger age halved the risk of rapid progression in fast changing myopia. (1) Orthokeratology are suitable for children, adolescents and adults, however this study showed that the ideal age to commence Orthok for myopia control benefits is 6 to <9 years old.  (1) Older children including adolescents also demonstrated reduced myopic progression and slower eyeball growth, for those with fast progressing myopia (1)

“For all three groups, mean axial elongation of the right eyes was slower during ortho-k treatment compared to the spectacle-wearing phase but the young children showed the fastest elongation in both phases of the study,” Professor Cho stated. (1)

Children in the 6 to <9 years old bracket demonstrated a reduction from 86% to 43% progression, and children 9 to <13 years showed a drop from 17% to 0% myopic progression, when changing from spectacle to Orthok lenses. (1)  No adolescents showed fast progression in glasses or Orthok lenses. (1)

Orthok may be used to correct for myopia in adults as well, however research is needed to investigate its role in slowing progression. (1)

The take home message is that optometrists and clinicians should discuss myopia control options with all progressing myopic children, and keep in mind the potential rapid progression in early childhood. This discussion should include a shared-care decision plan between the child, parents and optometrist; addressing risk factors such minimal outside time, extensive near-time & close working distances for near-tasks, and optometric myopia control options including soft multifocal contact lenses, Atropine eye drops with optical correction  and Orthokeratology. (2-4). Patients wishing to commence Orthok, should be referred to an Ortho-k fitting optometrist.

Proudly announcing the new Fellows of the International Academy of Orthokeratology (FIAO)

Orthokeratology Society of Oceania - Saturday, September 24, 2016
Fellowship of the International Academy of Orthokeratology (FIAO) is determined by an orthokeratologists experience and expertise. Rigorous written case presentations are followed by written and oral examinations. Those rare orthokeratologists who achieve fellowship status display the highest level of knowledge and are committed to adhering to the highest standards of care.

The OSO, until recently, only had 2 members that had achieved the accolade of FIAO – Oliver Woo and Duc Pham.

We are proud to announce that today another 7 OSO members were awarded FIAO – Gavin Boneham, Celia Bloxsom, Eleisha Dudson, Shonit Jagmohan, Jagrut Lallu, Alex Petty and Lachlan Scott-Hoy.

Congratulations to all of you on your magnificent achievement and your dedication to orthoK!!!

West Australian researchers shedding light on myopia causes

Orthokeratology Society of Oceania - Tuesday, September 06, 2016

Emma Wynne of 720 ABC Perth reports that researchers at the University of Western Australia are trying to find a possible link between the growing rates of myopia and how sun exposure, time in the classroom and genetics combine to cause it. Read the full article
