N2 - Improvements in soft lens technology have provided practitioners with increasingly greater oxygen permeable materials. The importance of oxygen transmission to the cornea is well documented. This paper describes the efficacy of using a soft extended wear lens design on a daily wear basis. A daily wear clinical investigation was conducted using 20 patients over a 6-month period wearing an Optima 38 daily wear lens on one eye and an Optima EW lens on the other eye. No significant differences were noted pertaining to ocular signs or symptoms between the two lenses. It was concluded that, with the knowledge that it provides for enhanced corneal transmission and, therefore, physiology, the Optima EW lens material employed on a daily wear basis appears to provide comfort, visual acuity, and handling properties equivalent to that of the Optima 38 daily wear lens.
