What is Orthokeratology?
What is Orthokeratology?
This means the adaptation, elimination or decrease of the refractive adjustment by the use of contact lenses. The lenses are used to restabilise the cornea and to decrease the shortsightedness and astigmatism of the eye. The process is comparable to orthodontic straightening of teeth, with a difference: while teeth remain strengthened for an indefinite period, the cornea, being elastic, returns quickly to its original form. The lens is worn during the night and taken off in the morning. Correct vision is achieved with regular use, with no need for glasses or contact lenses during the day.

The lenses are suitable for powers of up to –4.50 spherical diopters and up to –1.00 cylindrical diopters.
For higher prescriptions it is possible to reduce the power slightly.
The lenses are unsuitable good for irregularly flat or convex corneas.
Unknown factors such as cornea complexity and flexibility can affect the level of adjustment.
Although success rate is very high, 100% success cannot be promised.
What is the procedure?
What is the procedure?
First of all, a complete eye evaluation has to be carried out, including corneal topography and a vision check. This allows the optometrist to evaluate the health of the eye and cornea, and the suitability of the candidate.
The client receives a pair of Soflex Overnight lenses made of an elastic material with very high oxygen permeability, to be worn during the night. The morning afterwards, the client will returns for an eye examination and an evaluation of the changes in the cornea.
A week later, another examination and cornea evaluation is being carried out.
Most significant changes occur during the first few days, while final stabilization of the cornea occurs at a slower pace, during a period of up to three months, depending on the level of myopia.
Wearing time depends on several factors, but the ultimate aim is for the client to wear the lenses every two or three nights, and to see correctly during the following days without the need of glasses or contact lenses.

Is this a revolutionary new treatment?
Is this a revolutionary new treatment?
Yes and no. The principles of the method were determined in 1962.
However, today’s computer technology, oxygen permeable raw materials and high-precision instruments such as the Corneal topographer, promise a higher success rate than ever.

This treatment has helped many people become independent of glasses and contact lenses while incurring no damage to the eyes. Unlike with keratotomy, there is no damage to the eyes or corneas such as scarring, which might cause problems with night sight. However, contact lenses must be properly maintained to ensure that the eyes remain healthy.

The maintenance lenses must be used on a regular basis and according to the optometrist’s instructions or the prescription will return to its original status.
