Orthokeratology, also know as OrthoK
Contact lenses that work whilst you sleep for clear vision during the day
Orthokeratology, also known as OrthoK, is a well established treatment program for vision correction to enjoy the freedom from spectacles or contacts lenses throughout the day. Custom-designed hard contact lenses are to be worn whilst sleeping which then upon removal in the morning, the result is an immediate improvement of vision.
OrthoK can be used for most prescriptions, however it is most commonly used in children and teenagers to slow shortsightedness, or myopia. Studies have shown it to be as effective as a 50% reduction in progression, making it one of the leading interventions to manage myopia in children and teenagers.
The lenses work by gently reshaping the front structure of the eye, the cornea. This is temporary and reversible upon discontinuation of use, however worn consistently these lenses can be an effective treatment for many years.
Our specialised OrthoK lenses are custom made for every individual patient and take into account unique eye shapes, features and prescriptions. Initial wear of these lenses may take some time to adjust but comfort and vision improves within a few days. In some cases your current glasses or contact lenses are only still needed for the first few days of treatment, sometimes they’re not needed at all!
OrthoK is a long term treatment and we look forward to assisting you to achieve functional, clear unaided vision. To ensure success we will work closely together and we ask you to:
- Cease use of contact lenses for at least one week prior to initial measurement appointment.
- Attend all scheduled appointments – Regular follow up is an essential component to long-term success
- Follow the prescribed lenses and lens care system
- Comply with the prescribed wearing schedule for the lenses
- Contact us if you have any concerns or adverse effects
As always, the health of your eyes is our primary concern. All contact lens wear carries a risk of eye infections, however hard contact lenses and OrthoK has relatively lower risks of adverse effects. With proper care and maintenance, the risk of inflammation and bacterial infections due to poor hygiene can be minimised.
