JACKSONVILLE, Fla.—The 1-Day Acuvue TruEye contact lens from Vistakon Division of Johnson & Johnson Vision Care, Inc. is now available in a more comfortable material that fits more patients. The narafilcon A silicone hydrogel material will gradually replace the narafilcon B material currently available in the same product launched in the U.S. in 2010.

A majority of the material properties of narafilcon A are similar to narafilcon B, but they are different products, according to the company. One key difference is that the narafilcon A product is available in two base curves (8.5 and 9.0), allowing more patients to be fit with this lens. In a clinical trial, 99 percent of narafilcon B lens wearers had an acceptable fit with the narafilcon A product. In addition, narafilcon A has a DK/t of 118 for increased oxygen transmissibility with virtually no impact to modulus.

The silicone hydrogel daily disposable lens features Hydraclear 1 technology, which attracts tear film to help maintain the natural ocular environment for all-day comfort; high oxygen consumption, allowing 100 percent corneal oxygen consumption at all points across minus and plus powers for white, healthy-looking eyes; and class-1 ultraviolet blocking, offering the highest level of UV protection in the contact lens, blocking approximately 96 percent of UV-A rays and greater than 99 percent UV-B rays. The new 1-Day Acuvue TruEye (narafilcon A) will only be available in 90-packs, which research shows 95 percent of 1-Day Acuvue TruEye patients currently purchase. ■
