Orthokeratology Contact Lenses Compared

Orthokeratology contact lenses are gaining popularity, as they have proved to be effective in dealing with short-sightedness, long-sightedness as well as astigmatism. There is also a significant amount of evidence that orthokeratology can be used to control myopia in children. Consequently, as Dr Ronald K. Watanabe observes, there more and more orthokeratology contact lenses available on the market. In his article published in Contact Lens Spectrum, the expert provides presents two popular families of orthokeratology lenses.

The first one, the Paragon CRT family, which received marketing approval around 10 years ago, includes several versions of lenses: standard, Dual-Axis (very useful for patients with moderate astigmatism, which cannot be corrected with standard Paragon CRT lenses) and CRT for Hyperopia, steepening the centre of the cornea.

Another orthokeratology option that Dr Watanabe presents is Bausch + Lomb’s Vision Shaping Treatment system, including several designs (e.g. MiracLens, Emerald, DreamLens, BE Retainer, Orhofocus). Lenses belonging to this system utilise reverse geometry and reduce myopia by flattening the central cornea.

According to Dr Watanabe, all the above-mentioned lenses are quite effective as long as they are fitted properly and therefore it is the fitting process that is the most important element of orthokeratology treatment.
