Orthokeratology Near Sydney Airport

What is orthokeratology or orthok?

Orthokeratology, also known as ortho-k or night contact lenses, is a non-surgical, reversible method of correcting refractive errors such as nearsightedness (myopia), astigmatism, and mild farsightedness. It involves the use of specially designed rigid gas-permeable contact lenses that are worn overnight while sleeping for clear vision in your waking hours. 

How does orthokeratology work?

Ortho-k lenses are custom-made based on the measurements of your eyes. These lenses gently reshape the cornea while they are worn during sleep. The changes induced by the lenses compensate for the refractive error, effectively improving your vision. 

Is orthokeratology permanent?

The effects of orthokeratology are temporary, and regular nightly use of the lenses is necessary to maintain the corrected vision. If the lenses are discontinued, the cornea will gradually return to its original shape and refractive error. Whereas refractive laser surgery makes permanent alterations to the cornea.

What are the advantages of orthokeratology?

Orthokeratology provides clear vision without the need for daytime glasses or contact lenses, making it appealing for people who are active in sports or have professions that don't allow traditional vision correction methods. 


Another big advantage is that ortho-k is commonly used in children to significantly slow down the progression of myopia, therefore decreasing the risk of myopia related ocular diseases.


It is also an alternative for those who are not eligible for refractive surgery or prefer a reversible option. 

Am I suitable for orthokeratology?

It is important to consult with an eye care professional experienced in orthokeratology to determine if it is a suitable option and to receive proper guidance on lens fitting, usage, and maintenance. Make an appointment today by calling us on (02) 8542 2909 or booking online below.
