Lenses grouped into SiHy (delefilcon A, somofilcon A, narafilcon A) and Hy (omafilcon A, nelfilcon A). Biofinity has been shown to perform well in overnight swelling studies [3], showing no difference compared to lotrafilcon A after 8 hours overnight wear in 20 neophyte wearers at CCLR in Canada. Silicone hydrogel lenses are a more porous type of soft contact lens than regular hydrogel lenses, allowing more oxygen to enter the cornea.

In tests, neither material outperformed the other in terms of comfort, and both had a low incidence of contact lens related problems and complications. Published by Elsevier Espana. Limbal ring CLs magnify the eye appearance and this is achieved by adding pigments to these lenses. Keywords: 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. A prototype PremiO lens (with a different surface treatment to the commercial product) has been reported as similar in comfort and fitting for the 8.6 and 8.3 base curves, and compared to senofilcon A in short term contralateral evaluation [2]. A plasma surface treatment (Nanogloss) renders the surface of PremiO lenses smooth with a low contact angle of 27 (captive bubble method, Menicon data on file).
