Ortho K Technology Toronto Orthokeratology Treatment Lenses A: ortho k lenses are rigid gas permeable (rgp) contact lenses that are designed to be worn overnight and removed in the morning. ortho k lenses gently reshape the curvature of the eye to improve vision and control myopia progression. ortho k lenses are designed to float on top of the eye’s tear film and apply gentle water based (hydraulic. Here is a summary of the candidate factors described above, describing the ideal candidate for ortho k: good ocular health suitable for contact lens fitting 1. up to 4.50d of myopia. up to 1.50d of astigmatism for a spherical ortho k lens; up to 3.50d could be corrected with toric ortho k. aged between 6 and 35 years.

Orthokeratology Ortho K Infocus Optical Ortho k lenses are designed to float on top of the eye’s tear film and apply gentle water based (hydraulic) pressure to the front layer of the cornea, called the epithelium. the hydraulic pressure causes the cells of the epithelium to move from the center of the cornea to the periphery. this migration of corneal cells leads to a temporary. Ortho k lenses are designed for individuals with low to moderate myopia (up to 6.00d) with or without astigmatism (up to 1.75d). but beware of higher cylindrical correction and possible residual cylinder—you may reduce the myopia but leave appreciable higher order aberrations with uncorrected cylinder. • astigmatism. Orthokeratology lenses appear to be an effective clinical technique to control the progression of myopia. however, until large scale clinical trials have been conducted, we cannot forthrightly make this claim. though orthokeratology lenses are fda approved, employing them for myopia control is an off label use. Advanced technology has led to ortho k lenses that can correct hyperopia and presbyopia, but its most common application is for myopia. the lenses create myopic peripheral defocus that can reduce axial elongation. 1. do: learn as much as you can. each ortho k lens system has its own design and fitting philosophy.

The short answer is yes. ortho k provides a 50% myopia control effect, causing it to slow myopia progression by around half. 4,5 this means it's normal for myopia to progress even while wearing ortho k lenses for myopia control, and this should in fact be expected. how much myopia will progress while wearing ortho k lenses depends on many. Ortho k lenses are worn at night instead of during the day. they can temporarily change the shape of your eye to give you clear vision after you take them out without relying on any other visual aids. for children, the effects of ortho k lenses can also slow myopia progression, helping preserve their sight and reduce their risk of high myopia.
