SMARTSURFACE® Technology is a technology developed by Alcon Inc. currently found in the PRECISION1 product family. It was introduced in 2019 and is a result of Alcon's expertise in water-surface technologies.
SMARTSURFACE® is based on a special manufacturing process involving a series of liquid baths filled with water-loving polymers. This aqueous solution slightly expands the lens material creating small shallow lens pores in the two to three-micron thick lens surface. The water-loving polymer polyacrylic acid (PAA) penetrates the open pores and is locked into place creating a micro-thin layer of moisture.
This lock-in process takes place in an additional bath during the manufacturing process. In addition, with the lens in the blister pack, a special heating process is applied to complete the SMARTSURFACE building process by crosslinking the PAA polymer with wetting agents consisting of copolymers of polyamidoamine (PAE) and polyacrylamide-acrylic acid (PAAm-PAA).
This increases the moisture level from 51% in the core to over 80% at the lens surface.
