Orthokeratology, Ortho-K, is quite simple: as in orthodontics and orthopaedics, the ortho in Ortho-k is for correction. Orthodontics corrects teeth. Orthopaedics corrects skeletal injuries.
Orthokeratology corrects the cornea – the front surface of the eye.
It is a non-surgical, reversible procedure in which specially designed contact lenses are used to gently and gradually re-shape the cornea. The Ortho-K lenses are only worn during sleeping hours. On waking the lenses are removed. The reshaped corneal surface allows clear and natural vision for the rest of the waking day without the need for prescription glasses or contact lenses.
It is a process of gently moulding the cornea to reduce or eliminate shortsightedness and low astigmatism by the remoulding of the cornea by the contact lenses.
It is ideal for children and adults with prescriptions ranging from -1.00 to -6.00 dioptres of myopia (shortsightedness).
How does Ortho-K Work?
While you are asleep, the contact lenses gently reshape the front surface of your eye (cornea) producing a flatter central cornea and steepens the peripheral cornea correcting the nearsightedness.
Improvements in vision can usually be seen the next day with the procedure stabilising after a week.
The lenses are surprisingly comfortable to wear and most people comment that they forget they have lenses in the eyes after the first night of sleeping with them in.
