J&J Vision Care Unveils Digital Guide for Eye Care Professionals
Johnson & Johnson Vision Care Inc. launched an all-new Digital Guide by Acuvue Brand Contact Lenses, a resource to help eye care professionals develop or optimize a digital marketing strategy to encourage new patient visits, stay engaged with current patients, and keep them informed of new contact lens options.
The actionable and interactive guide includes topics such as Targeting, Websites, Social Media and more, with tips for reaching patients where they are online, simple updates to optimize a practice website, and effective ways for leveraging social media to reach different patient groups. It is available for free download from www.AcuvueProfessional.com, in the Practice Resources section. In addition to the Digital Guide, professionals can download and use a number of free, customizable assets, including digital banner ads, social media posts and email templates via www.MyAcuvueResourceCenter.com (free registration required).
Every chapter in the Digital Guide begins with an exercise to introduce a key concept to help give a better perspective of what a typical patient may encounter. After the concept is studied in detail, each chapter concludes with a worksheet that helps the professional to map out a digital strategy and next steps to begin reaching more patients. Professionals are able to spend more or less time on sections of the guide, based on their practice’s patient demographics, what is working in the current digital strategy, and the areas of their strategy that may need to be augmented.
B+L Specialty Vision Products Launches New 28 Lens Zenlens Diagnostic Set
Bausch + Lomb Specialty Vision Products business has launched the Zenlens diagnostic lenses in a new 28 lens set format. Adding to the classic Zenlens 24 lens Dx format, which features six lenses in two diameters (16 & 17mm) and two separate designs (prolate & oblate), the new 28 lens set adds four diagnostic lenses with toric peripheral curves.
The additional Dx lenses can help specialty lens fitters quickly and accurately assess scleral toricity to better determine proper peripheral lens toricity with the Zenlens toric peripheral system.

Missy Miserable has been wearing contact lenses for some time now. She has also been to three eyecare providers in the last 5 years. Each of them assured her that her prescription is not a problem for contact lenses. Her refractive error seems pretty simple -1.50-2.00X176 and -2.00-1.25X004. Missy says that she has tried all sorts of lenses, but they seem to be uncomfortable and she notes that the vision is not really crisp.
I saw Missy yesterday and puffed up my chest as I realized that she must not have tried my go-to-toric lens. Her refractive correction with spectacles is phenomenal, but she reports that her contact lens vision is a variable, so she didn’t wear the contact lenses into the office of course, because they didn’t work. I instructed my technician to help her with her new toric contact lenses and to evaluate her mires on the topography if she reports any variability to her vision.
After seeing the next patient I returned to the exam room to Missy who wasn’t super optimistic. I decided to take a quick look at Missy’s topography over the lenses and noted that my 14.ish diameter from the new lens was significantly overlapping Missy’s limbus. Using my topographer calipers, I noted that Missy’s corneal diameter is 10.9mm far smaller than usual.
With the significant sagittal depth difference between a lens that is made to fit a normal cornea, Missy’s lenses were not only fitting poorly, but also potentially flexing on her eyes.
I called up my good friends at a custom lens company that I use and shared all my parameters. They produced a custom set of lenses for now Made My Day Missy, who is ecstatic that she can now wear lenses for the duration of the day without variability in her vision.

Infrequent Contact Lens Use
One of the more challenging aspects of soft contact lens prescribing is getting your patients to replace their contact lenses on schedule.1,2 In general, most soft contact lenses are indicated for replacement on a daily, biweekly, or monthly basis,3 but how does a biweekly or monthly replacement schedule apply to infrequent contact lens wearers?
I have found that some patients define biweekly or monthly replacement schedules as fourteen or thirty different day’s worth of wear, which means that they may be using their same contact lenses for several weeks or even months. While it is understandable how patients may come to this conclusion, we should always remind our patients that they should be replacing their contact lenses at the recommended time, regardless of how many times they have worn their contact lenses.4
Infrequent contact lens use could potentially allow for microbes to build up between contact lens cleaning and use, especially if patients are using hydrogen peroxide solutions that neutralize to water.5 Thus, if you have a patient who wears their contact lenses infrequently, it may be best to prescribe them daily disposable contact lenses. This could decrease their chances of contracting a microbial infection,6 and it may also be the most cost effective method because daily disposable contact lenses are cheaper than biweekly and monthly contact lenses when the contact lenses are worn for about three days per week or less.7

A Randomized, Double-Masked, Placebo-Controlled Clinical Trial of Two Forms of Omega-3 Supplements for Treating Dry Eye Disease
The purpose of the study was to assess the efficacy of two forms of oral long-chain omega-3 (ω-3) essential fatty acid (EFA) supplements, phospholipid (krill oil) and triacylglyceride (fish oil), for treating dry eye disease (DED).
This randomized, double-masked, placebo-controlled clinical trial was conducted at a single site and involved 60 participants with mild to moderate DED who were randomized (1:1:1) to one of three groups: placebo (olive oil), krill oil, or fish oil supplements.
Participants received one of the three interventions: placebo (olive oil 1500 mg/day), krill oil (945 mg/day eicosapentaenoic acid [EPA], + 510 mg/day docosahexaenoic acid [DHA]), or fish oil (1000 mg/day EPA + 500 mg/day DHA) for 90 days, with monthly study visits.
Primary outcome measures were mean change in (1) tear osmolarity and (2) DED symptoms (Ocular Surface Disease Index [OSDI] score) between days 1 and 90. Secondary outcomes included mean change in key clinical signs (tear stability, tear production, ocular surface staining, bulbar and limbal redness, tear volume, anterior blepharitis, meibomian gland capping) and tear inflammatory cytokine levels.
In total, 54 participants completed the study. At day 90, tear osmolarity was reduced from baseline with both krill oil (mean ± standard error of the mean: -18.6±4.5 mOsmol/l; n = 18; P < 0.001) and fish oil (-19.8±3.9 mOsmol/l; n = 19; P < 0.001) supplements, compared with placebo (-1.5±4.4 mOsmol/l; n = 17). OSDI score was significantly reduced at day 90 relative to baseline in the krill oil group only, compared with placebo (-18.6±2.4 vs. -10.5±3.3; P = 0.02). At day 90, there were also relative improvements in tear breakup time and ocular bulbar redness, compared with placebo, for both forms of ω-3 EFAs. Basal tear levels of the proinflammatory cytokine interleukin 17A were significantly reduced in the krill oil group, compared with placebo, at day 90 (-27.1±10.9 vs. 46.5±30.4 pg/ml; P = 0.02).
The researchers concluded that a moderate daily dose of both forms of long-chain ω-3 EFAs, for 3 months, resulted in reduced tear osmolarity and increased tear stability in people with DED. Omega-3 EFAs in a predominantly phospholipid form (krill oil) may confer additional therapeutic benefit, with improvements in DED symptoms and lower basal tear levels of interleukin 17A, relative to placebo.
