Several aspects of the lens may be responsible. First, HydraLuxe Technology works continuously throughout the day to lubricate and moistur- ize the lens. On the eye, the lens supports the tear flm be- cause the lens is like the tear flm. In addition, the lens is extremely smooth. Tis has been demonstrated via transmission electron microscopy (TEM), which enables examination of contact lens surfaces under high magnifcation (i.e., sub-micron dimensions), allowing precise visualization of the surface and bulk or matrix of a material (Figure 3). 5 Tis has also been corrob- orated by atomic force microscopy (AFM) measurements (not shown). Additionally, these lenses also have a unique tear- infused design with an enhanced network of tear-like mol- ecules and highly breathable silicone that integrates with the patient's own tear flm. Tis uniform tear-like network exists throughout the en- tire lens; it is not just a surface coating. Te data shows that the low frictional energy profle of the lens lasts throughout the day. PROPER MOISTURE AND LUBRICATION Innovation leads to advancements and, ultimately, to patient benefts. ACUVUE OASYS 1-Day with HydraLuxe Technology lenses have demonstrated consis- tently low frictional energies through time when measured using a physiologically relevant methodology. Perhaps this is because the tear-infused design integrates key tear-like components — not just water — to moisturize and lubri- cate the lens throughout the day. In addition, the lenses are exceptionally smooth — as demonstrated by TEM and corroborated by AFM — and rather than employing a thin surface coating, they maintain a uniform, tear-like network throughout the entire lens. Clinical studies will deter- mine whether these lenses deliver the on-eye perfor- mance that their impressively low and stable frictional energy predicts. OM REFERENCES 1.
