We do Orthokeratology in Tzaneen!
Orthokeratology improves a broad spectrum of refractive errors up to certain extents. It corrects myopia, hyperopia and astigmatism. Theses contact lenses are expertly designed and manufactured for each eye individually. They require careful and frequent follow-up appointments with your contact lens practitioner.
How Does Orthokeratology work?
This is a very short exaggerated animation of how an Orthokeratology lens for Myopia will work. Before the lens touches the eye, the curve of the central cornea is quite steep. As the lens touches the eye and works during the night, the lens changes the curvature of the cornea slightly. When the lens is removed, the central cornea has a much flatter surface than before the treatment.
Again this is just an illustration and highly exaggerated.
How Long Does It Take To Work?
There is an improvement of unaided Visual Acuity already after one night of lens wear. The amount of time it will take to reduce the total power of the eye to plano is dependent on the prescription. To say this in other words. For a person with a prescription of -1.00 D, it will be faster to reach plano with treatment than for a person with a -5.00 D prescription. In total after two weeks of treatment, we want to the refractive power of the eye to be plano.
