The ESSTECH® MULTI Aspheric (multifocal) (hioxifilcon B) Soft (hydrophilic) Contact Lens is indicated for daily wear for the correction of refractive ametropia (myopia, hyperopia and/or presbyopia) in not-aphakic persons with non-diseased eyes. The lens may be worn by persons who may exhibit astigmatism of 1.50 diopters or less that does not interfere with visual acuity. The lens may be disinfected using either heat (thermal) or chemical (not heat) disinfection systems.

The ESSTECH® MULTI Aspheric (multifocal) (hioxifilcon B) Soft (hydrophilic) Contact Lens is available as a lens with an aspheric front surface for the correction of visual acuity in presbyopic persons who are myopic or hyperopic. The lens is constructed to provide optimum edge thickness and contour, with the central area providing the reading power in the equivalent of a 2.00 diopter near addition. The aspheric front curve undergoes a progressive power change, resulting in intermediate and distance power outward from the center. The lens is a flexible transparent shell of the following dimensions: Chord diameter: Baber: steps) The lens material, hioxifilcon B, is a hydrophilic co-polymer of glycerol methacrylate (GMA) and 2-hydroxyethyl methacrylate (2-Hema), crosslinked with ethylene glycol dimethacrylate. The lens is swollen to equilibrium state in sterile buffered saline solution, and contains 48% water by weight when fully
