In the contactology practice the management of myopia represents a challenge for all professionals; many published studies (1) have shown that the use of ortho-k RGP is effective in myopic progression, but it is certain that not all subjects are ideal candidates. In case of worsening it is possible to follow the refractive variation, adjusting the correction in use with spherical and toric contact lenses, or to seek an equilibrium in the compensation through Myopic, which associates to the distance power an area of control of the peripheral defocus.

soft cl and myopia

With reference to the orthokeratological effects, visible in corneal topography in the post application, and on the basis of the company’s know-how, aimed at the production of multifocal designs, it was possible to associate the soft monofocal lenses (spherical and torical) a paracentral area for modulation of positive spherical aberration.

spheric and toric dynamic

The range provides maximum customization, to facilitate the adaptation to the ocular characteristics of the subject. At the level of corrective options, there are spherical geometry contact lenses, for simple myopia, and back toric with optimized dynamic stabilization, to compensate for the myopia associated with astigmatism.

selectium criteria

Myopic fitting follows normal parameter selection procedures and application of soft TS lenses. The coverage ratio and the movement at the wink and in the different viewing positions must meet the stability and balance criteria, to maximise corrective effectiveness and reduce optical interference.

 

suggested polymers

The production choice is based on the association of Myopic design with silicone materials (SH), with high Dk and frequent replacement, to favor the daytime port of many hours and ideal performances. Optimized thicknesses and dynamic stabilization in the toric ensure comfort even in younger subjects.
