The Orthokeratology Society of Oceania (OSO) is dedicated to promoting research, professional development and networking in the orthokeratology field since 1984. On this site you will find all you need to know about the OSO, and the exciting field of orthokeratology - a non-surgical means of correcting vision while you sleep.
Orthokeratology is the "reduction, modification or elimination of a refractive error by the programmed application of contact lenses". If you are an optometrist, ophthalmologist, researcher or student, our members’ section will keep you up-to-date with the latest optometric news from across the globe. You will also have access to continuing education, networking, research grant and fellowship opportunities with the OSO, as well as information about new products coming to market.
