Some custom soft contacts are now made with advanced silicone hydrogel materials that allow more oxygen to reach the eye than conventional soft lens materials. For example, Contamac, a U.K.-based company, recently received FDA approval to supply a proprietary silicone hydrogel material to optical labs in the United States for the fabrication and sale of custom soft lenses. The material, called Definitive, can be lathe-cut in a manner similar to how rigid gas permeable contacts are manufactured, for a virtually unlimited degree of customization.
