This is a popular monthly reusable contact lens. The main advantage of this lens is that is the least likely to get a build up of deposits due to its design. Alcon uses their ‘permanent plasma technology’ by creating a permanent plasma surface created by a fusion process. This permanent surface minimizes the mobility of the hydrophilic and hydrophobic sites during blinks by preventing the silicone in the lens material from being exposed to the air. This smooth protective surface allows tears to spread evenly over it, promoting moisture retention and minimal deposit buildup. Patients find the quality of vision and comfort of this lens very good.
