Thea Pharmaceuticals Launches Blephademodex Eye Lid Wipes
Thea Pharmaceuticals has extended the Blepha range of lid care products with the launch of Blephademodex Eye Lid Wipes. According to the company, Blephademodex cleans away crusts, eyelash dandruff, impurities, mites, and debris on eyelids and eyelashes that cause eyelid inflammation and improves symptoms linked to Demodex infestation.
Blephademodex has two key active ingredients: terpinen-4-ol, a purified active extract from tea tree oil, which at a low concentration of 2.5% is used for its antimicrobial and anti-inflammatory properties; and sodium hyaluronate, a natural skin soothing and moisturizing agent. The preservative-free Blephademodex is available in boxes of 30 sterile ready-to-use wipes.
Are scleral contact lenses impacting the rate of corneal transplants in your practice?
Even the best-fit scleral lenses cannot always correct residual higher-order aberrations. Practitioners, lens designers, software, and equipment engineers are working together in an effort to address this issue that frustrates patients and professionals alike. Look for significant progress in the future.

Contact Lens Options for Myopia
As eyecare providers, we are not "myopic" to the prevalence of myopia. Incidence can depend on geography, with general trends of higher rates in Asian populations. It is estimated that myopia will continue to increase over the next few decades.1 Myopia has been linked to genetic factors, such as parents who have myopia. Environmental factors, such as near work and reading, can additionally play a role in myopia. Myopia is also more common in urban areas, with higher rates among professionals, with higher levels of education, and with high computer use.2 Thus, it is no surprise that a huge amount of effort is invested into controlling myopia. Of the tools available, contact lenses demonstrate some promise.
Studies using multifocal contact lenses have demonstrated promising results in terms of overall slowing of myopia and also reducing axial length. Mostly distance-center, concentric alternating areas of distance and near powers have shown promise.3,4 Orthokeratology, which both flattens the cornea, helping to control axial length by redirecting light rays hitting the peripheral retina, has been widely studied. Both modalities have been shown to control myopia progression by 40% and axial elongation by up to 50% compared to traditional single-vision modalities.3,4 Thus, contact lens options may be worth exploring in young myopic patients.

New, New, New
The following statement does not seem like news anymore: "A new lens was released by XYZ company, and executive ABC claims that the improvement seen in research will positively affect patients’ lives." Admit it, you have received these press releases and have seen them regularly published in our journals. At present, nearly every company has completed the family for its lenses (yes, exceptions exist, and that press release will probably come out tomorrow). Is this news exciting and impactful anymore?
As I travel the world talking about contact lenses, I enjoy asking practitioners about their prescribing habits. What I tend to discover is an approach to lens fitting along the lines of: If it ain’t broke, don’t fix it (i.e., once patients have a problem in this lens, we will consider moving them). I understand this from a practice management/patient flow standpoint. Why shift something and require a follow up or the potential for additional visits? However—pushing the practice management side of things aside—if we wait until something breaks, it may be harder to fix.
In reality, if patients become uncomfortable with a long-standing lens, it is because of damage to the ocular surface, not because the contact lens changed. I would encourage you to look at your prescribing habits and ask: Am I pushing toward better health and a more improved lens?
I personally believe that the best avenue for this is with daily disposable lenses. Once you start seeing the innovations as an opportunity to save vision and comfort, "new, new, new" will become exciting all over again.
Diversity of Ocular Surface Bacterial Microbiome Adherent to Worn Contact Lenses and Bacterial Communities Associated With Care Solution Use
The purpose of this study was to assess the microbiome adherent to contact lenses and to define the bacterial communities associated with the use of lens care solutions.
Among 84 lenses screened for an adherent ocular surface bacterial microbiome using 16S rRNA molecular amplification, 63 (75%) generated bacterial-specific amplicons processed using the Ion Torrent Personal Genome Machine workflow. Data were stratified by solution use (peroxide versus polyhexamethylene biguanide [PHMB]-preserved multipurpose solution [MPS]). Diversity of the lens-adherent microbiome was characterized using the Shannon diversity index and richness index. Data were analyzed using principal components analysis and Kruskal-Wallis tests.
The authors identified 19 phyla and 167 genera of bacteria adherent to the lenses. Proteobacteria was the most abundant phyla, followed by Firmicutes and Actinobacteria. The most abundant bacterial genera (> 1% abundance) were Ralstonia, Enterococcus, Streptococcus, Halomonas, Corynebacterium, Staphylococcus, Acinetobacter, Shewanella, Rhodococcus, and Cobetia. Sixteen of 20 lenses (80%) that were negative for bacterial DNA were worn by participants using peroxide solutions, while only four (20%) were MPS-treated lenses (P = 0.004). Genera diversity of the lens-adherent microbiome was significantly increased in MPS-treated lenses compared with peroxide (P = 0.038). Abundance of Corynebacterium, Haemophilus, and Streptococcus were increased 4.3-, 12.3-, and 2.7-fold, respectively, in the MPS group compared with peroxide (P = 0.014, 0.006, and 0.047, respectively).
The researchers concluded that commensal, environmental, and pathogenic bacteria known to be present in the conjunctival microbiome can be detected on worn contact lenses. Although most contact lenses worn by asymptomatic wearers harbor bacterial DNA, compared with peroxide, lenses stored in a PHMB-preserved MPS have more quantifiable, abundant, and diverse bacterial communities adhered to them.
