What is it?         

Ortho K is a non-surgical process which uses therapeutic contact lenses that the patient sleeps in at night. On waking the lenses are removed and clear vision is restored without the need for glasses or contact lenses throughout the day. The Ortho K lenses gently reshape the cornea to provide the wearer with clear vision. The effect is reversible and the lenses must be worn each night. Initially it can take a few nights of wear before good vision is achieved, however this is dependent on the degree of myopia. 

Benefits of Ortho K

Slows myopia progression by up to 56%*

Reversible and non-surgical alternative for myopia management

Beneficial for those who suffer with dry eyes from soft contact lenses

No need for glasses or contact lenses during the day

Freedom of clearer vision for contact sports and other sports such as water polo

Who should consider this treatment?

Ortho K is more suited to short-sighted (or myopic) patients and can be done from 6 years of age. Ortho K has the greatest effect on patients that are no more than -6.00DS and have low levels of astigmatism, however we have been able to successfully fit individuals over -7.00DS.

Myopia is not the only vision condition that can be treated with Ortho K. Advances in technology have led to the correction of Hyperopia, Presbyopia and Astigmatism with Ortho K lenses.

What is involved?

An initial consultation is needed in order to assess the patients’ suitability for Ortho K. If the patient is suitable, multiple fitting appointments are needed in order for a successful contact lens fit. As a minimum, an initial fitting appointment, first day aftercare and subsequent reviews at 1 week, 2 weeks and then 6 monthly are needed to ensure appropriate fit and vision. As a result, Ortho K requires dedication by the wearer.
