Acuvue Oasys Lenses Supposed to be More Comfortable

VISTAKON-SPONSORED STUDY SUGGESTS SENOFILCON MATERIAL MAY HELP REDUCE COMMON PROBLEMS.


A recent study showed that lenses made with senofilcon A, a new silicone hydrogel material currently marketed in the United States as Acuvue Oasys contact lenses with Hydraclear Plus, were associated with a reduction in discomfort, dryness and other commonly reported problems associated with contact lens wear. Results of the study, which was sponsored by Vistakon, were published in Optometry and Vision Science and presented at the AAO annual meeting. Researchers evaluated clinical data from 1,092 current soft contact lens wearers to calculate the prevalence of six common signs and symptoms associated with contact lens discomfort. Nearly half (48 percent) showed at least one of the six criteria. Uncomfortable hours of wear at the end of the day (31 percent) was the most commonly reported problem, followed by frequent or constant dryness (28 percent) and discomfort (17 percent). Following the evaluation, 257 wearers were fit with senofilcon A lenses and reassessed two weeks later. Among subjects who reported problems before refitting, 88 percent said they noticed improvement in overall comfort, 76 percent in comfortable hours of wear and 75 percent in frequency of dryness.

DR. KEVIN'S COMMENTS:

Of course the study was sponsored by Vistakon so I have to be careful about this. I haven't been fitting these yet but I certainly will begin to based on these data. I fit primarily the Biomedics 55 Premier lens for comfort, the Proclear Compatibles for dryness, and Ciba Night and Day contact lenses for extended wear. I haven't gotten back to the B&L Purevision contact lenses yet, but before they were outlawed several years ago, I recall them being more comfortable than Night and Day. So I'll probably go back to them soon. I am excited about the Purevision Toric lenses coming out in January. This will allow me to fit toric lenses extended wear. I hope they work! Maybe I'll try this Acuvue Oasys lens. Since we're a medical practice, I don't get as many contact lens fits as more commercial settings, so the reps ignore me a little, especially from Vistakon. I'll have to track the rep down.
