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. coopervision.com/practitioner/build-your-practice/insight-newsletter/coopervision-unveils-biofinity-energys-contact-lenses. In June 2016, CooperVision announced the expanded availability of Biofinity XR toric, a monthly SiHy CL. When the water in hydrogel lenses gradually evaporates, for example, after many hours of wear or in dry or windy air, the material becomes drier and less comfortable to wear. Los ojos del grupo de Senofilcon reflejaron una considerable diferencia en cuanto a ausencia de movimiento de la lente (18 frente a 4, P = 0,0001). Nash W, Gabriel M. Ex vivo analysis of cholesterol deposition for commercially available silicone hydrogel contact lenses using a fluorometric enzymatic assay. This new material used silicone in a contact lens to allow more oxygen to flow to the cornea, increasing the comfort and clinical performance over hydrogel lenses. Clin Ophthalmol. Soft contact lenses may be easier to adjust to and are more comfortable than rigid gas permeable lenses. The challenge of prescribing the most suitable lens and solution for each patient based on their contact lens history, eye shape and prescription, and lifestyle, makes for interesting and rewarding practice. Further studies are warranted to understand the impact of these new technologies on CL comfort. Omali N, Subbaraman L, Coles-Brennan C, et al.

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). Mean pain score at day 1 was significantly higher in the Comfilcon group at 4.6 (SD 2.7) vs. 1.5 (SD2.5) in the Senofilcon group (P<0.005). Papas E, Dahms A, Tahhan N, Carnt N.

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.
