Orthokeratology Fundamentals
Instructors.
Paul GiffordAbout this course.
Orthokeratology Fundamentals will guide you through the theoretical and practical foundation to get started with your first few orthokeratology (OK) fits. Specifically designed for the new fitter, this course will set you up for success and build your confidence in fitting OK lenses.
You will first learn how OK works and the changes that these lenses make to the eye during overnight wear. With this knowledge under your belt, you’ll be guided through selecting your first patient; the clinical measurements that you should take and their interpretation to select the best lens to fit; dispensing and assessment of lens fit and eye health at follow up visits.

Meet the instructors.
Dr Paul Gifford is an eyecare industry innovator drawing on experience that includes every facet of optometry clinical practice, transitioning to research and academia with a PhD in ortho-k and contact lens optics, and now working full time on Myopia Profile, the world-leading educational platform that he co-founded with Dr Kate Gifford. Paul is an Adjunct Senior Lecturer at UNSW, Australia, and Visiting Associate Professor at University of Waterloo, Canada. He holds three professional fellowships, more than 50 peer reviewed and professional publications, has been conferred several prestigious research awards and grants, and has presented more than 60 conference lectures.
What you will learn.
Chapter 1: Welcome to Orthokeratology Fundamentals
Chapter 2: Important background knowledge
In this chapter you will learn how OK has evolved from fitting PMMA contact lenses as an attempt to alter corneal shape, to correcting refractive error into modern reverse geometry designs that provide accelerated effect during overnight wear. Types of OK lens design are covered alongside who you should and should not fit with OK.
Chapter 3: Corneal topography
OK lenses correct refractive error by temporarily altering corneal topography, which makes measuring and analyzing corneal topography an important skill for you to master. In this chapter you will learn how corneal topography works; tips to capture the best quality topography image; and how to analyze topography maps.
Chapter 4: Limitations of OK, patient selection and lens fitting procedure
This chapter builds on the first two chapters to understand how baseline corneal topography and refractive error influence lens fit, and the limits of correction that can be achieved from OK. You will then learn the steps to follow to select a first lens, its dispensing and instructions to provide your patient for their first night of lens wear.
Chapter 5: First night follow up
The response from the first night of lens wear can be variable, making the first follow-up visit more about ensuring your patient is proficient in lens handling than assessing lens fit and refraction outcomes. In this chapter you will learn what to expect and how to manage the different presentations, and how to manage shortfall in refraction correction while the OK effect improves over the next few days of lens wear.
Chapter 6: One week follow up
By one week of wear the full OK effect is expected, requiring you to understand the topography map patterns that represent different lens fit outcomes. Each map type is analysed in detail in this chapter, including description of the map characteristics that define each pattern type and advice on how to modify lens fit to improve fit and refraction outcomes.
Chapter 7: One month and beyond
With your patient now established in OK, your attention shifts to long term management. In this chapter you will learn when your patient should return for follow-up appointments, and the procedure to follow at these visits to maintain long term success from OK lens wear, alongside maximizing safety and ensuring continued good eye health.

Great
Good introduction to ortho k. Highly recommended
Easy to follow!
Great course- easy to follow and concepts explained well. I now have a much better understanding of what I am doing when I fit orthoK lenses.
I found it very useful, straightforward, not excesively long
Well explained, interesting basics, nor overlong, very understandable
