Bausch+Lomb ULTRA MoistureSeal technology: Information

Bausch + Lomb ULTRA� Contact Lenses

The Bausch + Lomb Ultra (samfilcon A) Visibility Tinted Soft (hydrophilic) Contact Lens is a soft hydrophilic contact lens which is available as a spherical lens.The lens material, samfilcon A, is a hydrophilic copolymer of a siloxane methacrylateand N-vinyl pyrrolidone, and is 46% water by weight when immersed in a sterileborate buffered saline with poloxamine solution.

The Bausch + Lomb Ultra (samfilcon A) Visibility Tinted Soft (hydrophilic) Contact Lenses, with samfilcon A lens material, are manufactured by the MositureSeal� manufacturing process, which combines lens molding through packaging in a continuous fashion by a cast molding process which creates a hydrophilic surface.The lens Maintains its Moisture up to 16 Hours.

The Lens �features the highest oxygen transmissibility (Dk/t 163) and lowest* modulus (70 g/mm2) compared to the competition.

The Lens��material is an ultimate solution for� demands of digital device users

Two-phase manufacturing process retains moisture and delivers a highly wettable surface1

Phase 1

• Combines long- and short-chain monomers to formulte a unique silicone backbone
• Produces a material that delivers a Dk/t of 163 and modulus of 70

Phase 2

• PVP grows around and throughout the silicone backbone

Bausch + Lomb ULTRA contact lenses have an aspheric optical design to reduce inherent and induced spherical aberration.
