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. According to the company, the lens can achieve greater than 80% water content on the surface.5 The comfort is attributed to the combination of the water gradient technology, low surface modulus of 0.025MPa (core of 0.76MPa), daily disposable modality and packaging in a phosphate-buffered saline solution containing 0.3% polymeric wetting agents (copolymers of polyamidoamine and poly[acrylamide-acrylic acid]).
