Effects of two different contact lenses on ocular. Invest Ophthalmol Vis Sci. eCollection 2018. These findings suggest that choice of material is a patient and practitioner preference; however, for patients at risk of hypoxia-related complications, SiHy materials should be considered. Rose K lenses are a frequently prescribed lens design for the correction of keratoconus and irregular cornea conditions and are mostly rigid gas permeable lenses. 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.

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 SynergEyes VS (Menicon) scleral lens completely vaults the cornea and limbus, landing entirely on the sclera.38 Its toric periphery may be precisely controlled in both the flat and steep meridians, aligning with the scleral for ease of landing and stability.38 This non-rotationally symmetrical lens design incorporates linear landing zones and landing zones with bi-tangential toricity.38 The linear landing zones are designed to follow the linear (rather than curved) shape of the sclera, accommodating a toric sclera.38 This should distribute the lens pressure more equally over the sclera due to the adjustable angles of the flat or steep meridians.38 The company hopes this will improve the scleral lens fit with less risk of air bubble formation or blanching of the conjunctival scleral vessels.38 The toric landing zones can greatly improve vision in patients with residual astigmatism as they are designed to provide consistent stabilization allowing for a front-surface cylinder. 2017;32:22-55. www.thevisioncouncil.org/content/digital-eye-strain, www.aaopt.org/coefficient-friction-and-soft-contact-lens-comfort, coopervision.com/practitioner/build-your-practice/insight-newsletter/coopervision-unveils-biofinity-energys-contact-lenses, www.bausch.com/our-products/contact-lenses/lenses-for-nearsighted-farsighted/bausch-lomb-ultra-contact-lenses/moistureseal-technology, www.artoptical.com/storage/docs/RKS_FG.pdf.
