Pigment location on seven different daily disposable limbal ring CL materials was studied and, aside from one lens material, all tested lens materials revealed pigments on the surface.54 The pigments located on the surface of the CL will either interact with the palpebral conjunctiva or the cornea depending on location of the surface coating (front or back). Int J Ophthalmol. The water gradient technology incorporates what the manufacturer calls core and surface optimization: the core material has 33% water content (low water content helps to deliver high oxygen transmissibility) and the surface employs a hydrophilic gel designed to provide lubricity (>80% water). Bergmanson J, Tukler J, Leach N, et al. 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]. Significantly more eyes demonstrated no lens movement in the Senofilcon group (18 vs. 4, P=0.0001). Effects of two different contact lenses on ocular. Pohan G, Mattiassi S, Yao Y, Zaw AM, Anderson DEJ, Cutiongco MFA, Hinds MT, Yim EKF. Please visit. Silicone hydrogel materials attract less protein than HEMA-based hydrogel materials, with < 10 g/lens for non-ionic and < 40 g/lens for charged silicone hydrogels [ 41 ]. These lenses have high oxygen transmissibility (Dk), low water content and relatively high lens modulus or stiffness. Before Fig. The Vision Council. Morgan P, Woods C, Tranoudis I, et al.

Compare the effects of two silicone-hydrogel bandage contact lenses on epithelial healing after photorefractive keratectomy with anterior segment optical coherence tomography. 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.
