The Rose K2 Soft design features an aspheric back optic zone, front surface toricity and front surface aberration control. In. Asian patients corneas have a smaller horizontal visible iris diameter and are more prolate with a smaller palpebral fissure than Caucasians corneas.35 Blanchard designed a lens (Onefit A Scleral lens) to provide optimal limbal clearance and easier handling with a smaller diameter and an altered paracentral geometry.36 Blanchard also launched a new feature called XLC (Extra Limbal Clearance), to its Onefit Scleral Lens Platform to obtain additional limbal clearance, without increasing the lens diameter. 2016. Limbal ring CLs magnify the eye appearance and this is achieved by adding pigments to these lenses. To compare subjective, objective and safety performance of silicone hydrogel (SiHy) daily disposable (DD) with hydrogel (Hy) DD contact lenses. Contact lens factors including centration, movement and deposits were assessed. These pigments can be located either on the surface or within the bulk of the limbal CL material.

Several papers in the peer-reviewed literature have demonstrated that contact lens wearers of omafilcon A typically experience less symptoms and signs of lens-related discomfort vs. wearers of other hydrogel materials, while others have not. Recent research shows a 32% to 42% reduction in myopia using orthokeratology (OK) lenses.39-41 Research also finds partial correction using OK lenses is effective, with high myopes of 6.00D or more partially treated by -4.00D, showing a 76% reduction in myopia progression over one year when compared with spectacle wear.42 Children fitted with a dual-focus multifocal OK lens design in one eye and a conventional OK lens in the fellow eye showed short-term changes to the eye in the multifocal OK lens wearing eyes.43, Concentric and aspheric multifocal designs can slow myopia progression.44 Concentric bifocal lenses, which have a center distance design surrounded by concentric zones of near and distance powers, reduce myopia progression and axial length in children with esophoric fixation disparities, according to investigators.44 Aspheric designs also show reduced myopia progression.45 Use of a center-distance aspheric multifocal design can reduce myopic progression by 50% and axial length by 29% when compared with a single vision wearing group.46, Dual-focus designs and peripheral plus powered aspheric designs also show myopia reduction; however, debate about the visual quality reduction caused by the induction of positive spherical aberration when using this approach persists.47-50. The newly launched Rose K2 Soft design is a daily wear SiHy soft lens for irregular corneas, available as a three-month replacement lens.
