A 12 month prospective clinical 30 night contralateral extended wear trial in Australia by Noel Brennans group showed better performance for Biofinity for some comfort scores compared to lotrafilcon A and balafilcon A, and some vision variables, objective redness and conjunctival staining compared to lotrafilcon A. Lenses grouped into SiHy (delefilcon A, somofilcon A, narafilcon A) and Hy (omafilcon A, nelfilcon A). Unauthorized use of these marks is strictly prohibited. The FDA classifies soft contact lenses into four groups for the US market. 2013;54:TFOS20-36.5. In August 2016, CooperVision announced the launch of a new SiHy lens, Avaira Vitality (CooperVision), in sphere and toric options, manufactured from fanfilcon A, which has a high water content (55%) and high oxygen permeability (Dk) and transmissibility level (Dk/t). (Clinical Trial), This will be a, prospective, double-masked, randomized, bilateral, 1 week cross-over, dispensing study. It is FDA-approved for up to six nights and seven days of continuous wear due to its relatively high oxygen transmissibility value (103-147 Dk/t). Biofinity and Avaira do not have surface coating or intrinsic wetting agent. Together with your eye doctor, you can learn the benefits of each and determine which is the best choice for you. 2019 Nov 5;13:2159-2165. doi: 10.2147/OPTH.S224450.

In July, CooperVision introduced its Biofinity Energys (CooperVision), with digital device users in mind. . Careers. 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. Lenses grouped into SiHy (delefilcon A, somofilcon A, narafilcon A) and Hy (omafilcon A, nelfilcon A). 48 eyes of 24 patients were included in the study. 2013;36(Suppl.):e2.44.

[9,10] While Biofinity [9] and PremiO [11] lenses perform well in short-term testing, longer term evaluation of Biofinity, PremiO and Avaira is essential as SICS has been associated with a 3-fold increase in low grade corneal inflammation [12] and decreased comfort. 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.

INTRODUCTION. https://synergeyes.com/professional/specialty-contact-lenses-scleral-vs/. Menicon recently launched Rose K2 Soft CL design for the irregular cornea. Se evaluaron factores sobre lentes de contacto tales como centrado, movimiento y depsitos. In most instances, silicon enrichment at the outermost surface was observed, resulting from differences in lens formulation and design. When hydrated the lens consists of 44.0% somofilcon A and 56.0% water by weight of saline CooperVision announced the limited rollout of Avaira Vitality toric (in the fanfilcon A material). This material now accounts for approximately 55% of all soft lens fits worldwide and 62% in the United States.7 Its increased oxygen transmissibility promised a reduction in the rate of corneal infections, but research shows the risk of microbial keratitis is similar regardless of lens material studied.8-12 In fact, several studies show that SiHy materials doubled the relative risk for infiltrative events.13-16 Studies also suggest that older generation SiHy materials provided only a minimal increase in comfort over conventional hydrogel (CH) materials.5,17 This was due to the incorporation of siloxane groups into SiHy lenses, which made them more hydrophobic and stiffer than CH materials, but led to issues related to poor lens wettability and mechanical complications.18-20 These mechanical complications included mucin balls (Figure 1), corneal erosions (Figure 2), superior epithelial arcuate lesions (Figure 3), epithelial flaps and CL-associated papillary conjunctivitis.21-26 The hydrophobic nature of certain SiHy materials tends to deposit high levels of certain lipids and increased denatured protein.27,28 Hence, several practitioners still choose to fit CH materials. Before analysis, each lens was removed from its blister pack and placed in 5 mL of phosphate buffered saline (PBS) (Mediatech Inc., Manassas, VA) for a minimum of 24 hr.
