Summary: Soft toric contact lenses have been on the market for several years. Key aspect is how the lens is positioned on the eye surface. Lens must maintain its’ proper position not only during examination, but during everyday use as well. Recently, new technical solutions have been introduced in the manufacturing process. Traditional dual zone stabilization systems, known as prism ballast and slab-off zones are now being replaced by system of many active zones. The blinking forces stabilize the lens when the lens id displaced and are minimal when the lens is in the correct position. The better stability on the eye means more comfort for the patient, easier fitting process and better visual acuity in everyday life.
