Acknowledging renewed interest worldwide, the Centre for Ocular Research & Education (CORE) has dedicated Issue 82 of Contact Lens Update to orthokeratology (ortho-k).  

“Although ortho-k lenses are widely recognised for their role in slowing myopia progression, they were initially developed for the correction of both myopia and astigmatism. These lenses can also correct hyperopia, astigmatism and presbyopia by reshaping the cornea overnight — incredible, high-precision technology deserving more recognition,” said Daddi Fadel, clinical scientist at CORE. “This non-surgical approach allows patients to experience clear vision throughout the day without the need for glasses or soft contact lenses. We developed the latest issue of Contact Lens Update to help eyecare professionals make even more use of the approach.” 

Myopia Profile co-founder and optometrist Paul Gifford, adjunct senior lecturer at University of New South Wales Sydney and a visiting associate professor at the University of Waterloo, provides an overview of the advancements of ortho-k, its broad applications across the refractive spectrum and its role in modern vision correction. He highlights its effectiveness, safety profile and practical benefits, reinforcing the importance of integrating ortho-k into clinical practice for both children and adults. 

Asif Iqbal, who is pursuing his PhD in specialty contact lenses at the Contact Lens and Visual Optics Lab, Queensland University of Technology (QUT), and Stephen Vincent, director of the Centre for Vision and Eye Research at QUT, authored the issue’s feature which investigates the effects of overnight ortho-k on corneal tissue thickness in adult myopes.
