FEATURE ARTICLE Daily Disposable Contact Lenses; Here today, gone tomorrow? Jacob r. lang, oD, faao according to a recent publication by efron, et al. prescribing habits of daily disposable contact lenses by country fall into two distinct groups: high prescribing nations (Japan 32%, norway 38% and the UK 32%) and low prescribing nations (australia 11%, canada 8%, the netherlands 5% and the Us 5%). However, in this article the authors also describe that in all countries, but especially in the lower prescribing nations, there appears to have been a sharp increase in the rate of prescribing daily disposable lenses. Daily disposable contacts have been available in the United States for more than 15 years. In that time we have seen expanded parameters and powers, improved comfort and now daily lenses are even available in cutting edge silicone hydrogel materials. All major manufacturers have a daily lens modality available, each with their own advantages. We currently have daily disposable lenses that can correct the great majority of our patients’ refractive errors with great strides being made in the availability of astigmatic power and axis, as well as overall power ranges. However, these lenses are still not a mainstay in the prescribing habits of many practitioners. According to a recent publication by Efron, et al. prescribing habits of daily disposable contact lenses by country fall into two distinct groups: high prescribing nations (Japan 32%, Norway 38% and the UK 32%) and low prescribing nations (Australia 11%, Canada 8%, The Netherlands 5% and the US 5%). However, in this article the authors also describe that in all countries, but especially in the lower prescribing nations there appears to have been a sharp increase in the rate of prescribing daily disposable lenses. Also interesting was that practitioners prescribe this modality to males significantly more often than they do to women. This was especially true in Canada, where 41% of males were fit with daily disposable lenses and 32% with reusable lenses. I found it surprising that only 8% of fits in Canada are into daily lenses, but almost half of the men fit in lenses are into a daily disposable lens. I believe these numbers are a sign of things to come. In my opinion patients are more interested in these lenses than ever before and practitioners are able to meet more and more of the visual and lifestyle demands of their contact lens patients with these lenses. This combination of advancements position daily disposables for an exponential increase in the upcoming years. There is no such thing as a perfect contact lens. Every lens has its own advantages, disadvantages, quirks and niches. Everyone wants their patients to have healthy eyes and great vision. Undoubtedly daily disposable contacts have proven that they have a lot of advantages to offer. Let’s explore these advantages first. The Good I think everyone can agree that a lens degrades with the continued handling, cleaning, environmental exposure, and general wear regardless of the material, coatings or other additives the lens may have. The biggest advantage of any disposable contact lens is that we are minimizing these degradative processes by using a new lens at the prescribed interval. The daily disposable modality minimizes degradation JaCob r. Lang, oD, Faao Dr. lang currently practices at associated eye care in stillwater, minnesota.
