O2 Optix Custom™ is the first and only made-to-order silicone hydrogel lens from a worldwide leader in silicone hydrogel technology. Unlike stocked silicone hydrogel contact lenses which are cast molded, custom lenses generally require high-precision lathing. Since pure silicone is very rubbery and doesn’t lend itself to being cut on a lathe, CIBA Vision material chemists invented an exciting new silicone hydrogel formulation called sifilcon A that has a unique property that allows it to be lathed. O2 Optix Custom™ features a patented, permanent, biocompatible plasma surface treatment that resists deposits to contribute to healthy lens wear. With this unique surface treatment, O2 Optix Custom™ contact lenses can be worn comfortably for up to three months of daily wear. Lens Type: Quarterly disposable, soft contact lenses Package Details: 4 sterile, handling tinted soft contact lenses immersed in phosphate buffered saline solution Material and % of content: 68% polymer (Sifilcon A) Water % of content: 32% Manufacturer: CIBA Vision Corp. Duluth, GA
