We just wrapped up our 12th annual Global Specialty Lens Symposium (GSLS) in Las Vegas (www.gslsymposium.com). There were more than 950 people in attendance, making it one of the largest conferences of this type globally. Yet, despite its size, the meeting has been able to maintain its focus and provide cutting-edge information on all aspects of contact lenses. As we think ahead to planning for the 2019 GSLS, we would welcome any thoughts on topics we should consider for the agenda. Please email them to firstname.lastname@example.org.

CooperVision Issues “Digital Device Usage and Your Eyes” Report
CooperVision, Inc. recently released its “Digital Device Usage and Your Eyes” report, highlighting new global research on consumer use of digital devices in relation to eye health. A multifaceted survey was conducted among thousands of respondents in Australia, France, Germany, Japan, Spain, the United Kingdom, and the United States. The report is available for immediate download from CooperVision.com/digital-report.
The research showed that both contact lens wearers and non-wearers worry about how much they use digital devices. Globally, 19% of people who use vision correction (and 18% of people who do not) express concern about the amount of time spent looking at screens. This edges higher—to 26% globally—for contact lens wearers.
Globally, just 14% of contact lens wearers reported that they had spoken with an eyecare professional (ECP) regarding digital device use. Yet, 78% of contact lens wearers—nearly four in five—said they would be very or somewhat interested in exploring ways to reduce eye tiredness with their ECP, according to the report.
The report also highlights how respondents cope with the ocular discomfort from digital device use, which phrases they use to describe how their eyes feel after long periods of screen viewing, and similarities and differences among consumers depending on where they live.
A follow-up survey in six nations revealed that nearly one in three contact lens wearers are willing to pay a premium for an option that reduces symptoms of digital eye fatigue.
Optometry Giving Sight to Merge with Brien Holden Vision Institute Foundation
The global board of Optometry Giving Sight announced that it will merge its operations into the Brien Holden Vision Institute Foundation. According to the organizations, the decision was based on a desire to ensure that by working more closely together, the entities could achieve more significant and sustained outcomes to benefit the millions of people who are needlessly blind or vision impaired simply because they can’t access an eye exam and glasses from a qualified optometrist.
All current global board members have been invited to continue to support the campaign as part of a newly formed advisory board, and Dr. Juan Carlos Aragón will join the board of the Brien Holden Vision Institute Foundation. All current agreements with Optometry Giving Sight project partners will continue, and the Optometry Giving Sight brand will be maintained.
Clive Miller finished up as Optometry Giving Sight CEO in December 2017 and has since accepted the newly created role of Global Head of Philanthropy for the foundation. All other Optometry Giving Sight staff will remain working in the merged organization.
VTI Achieves CE Mark for NaturalVue Family of 1 Day Lenses
Visioneering Technologies, Inc. (VTI) announced receipt of the European CE Mark for commercialization in the European Union of its portfolio of proprietary NaturalVue (etafilcon A) brand 1 Day Contact Lenses, including sphere, toric, multifocal, and multifocal toric. VTI’s CE Mark includes an indication for VTI’s NaturalVue Multifocal (NVMF) for myopia progression control (the control of progressive nearsightedness). NVMF contact lenses feature VTI’s Neurofocus Optics Technology, which employs a patented extended depth-of-focus design to address known optical risk factors associated with myopia progression. The NVMF lens design allows it to be used for both myopia progression control and presbyopia (the age-related loss of ability to see near objects), according to the company.
The CE Mark allows VTI to commercialize its contact lens products in Europe as well as to prepare regulatory submissions to launch its products in additional countries, including Australia, New Zealand, Hong Kong, Singapore, and others.
Five optometry students from the United States and Canada presented scientific posters at the 2018 Global Specialty Lens Symposium in Las Vegas last month as winners of the Optometry Student Challenge, a program designed by ABB Optical Group, in partnership with Paragon Vision Sciences, to foster the study of contact lenses.
The lead authors of the scientific posters were Theodore Chow of the Indiana University School of Optometry, Gabriella Courey of the University of Montreal School of Optometry, Yuno Iwabuchi of Pacific University, Kiri Rutledge of the Northeastern State University Oklahoma College of Optometry, and Stephanie Sonnenburg of the Illinois College of Optometry. Honorable mentions were given to Candice Moore and Ashley Noble, both students at Nova Southeastern University, and Stephanie Tran, a student at the Inter American University of Puerto Rico School of Optometry.
More than 65 optometry students submitted abstracts focusing on study projects or student-based case histories related to contact lenses for the chance to win a travel stipend of $1,500 to attend the symposium and convert their abstracts into scientific posters. The challenge was open to students in their third and fourth years of study. Abstracts were judged on academic merit by a panel of industry experts.

CARE SOLUTION CORNER

Videos for Patient Education
People commonly say that a picture is worth a thousand words. I have found this to be especially true when it comes to educating my patients. Early on in my training, I discovered that many patients lack a basic understanding of ocular anatomy and that simply showing them a picture of the eye can make the difference between them leaving with a good understanding of conditions such as myopia and them being completely befuddled and frustrated. With this in mind, I became interested in better understanding whether videos could provide added value to my routine contact lens care and compliance education.
The literature suggests that educational videos may vastly improve a patient’s understanding of complex medical topics.1 They also found that videos were able to decrease a patient’s anxiety; the videos also improved overall patient satisfaction.1 Providing an educational video was likewise found to decrease the amount of time that a practitioner needed to spend on in-office education.1
Overall, I think incorporating self-created or borrowed contact lens educational videos (and videos on other important eyecare topics) into our in-office and take-home education (provided via a website or patient portal) will result in better-informed, happier, and more compliant patients, a feat that is especially challenging when it comes to contact lens wearers who typically need to complete a long list of tasks on a daily basis.2,3 Videos may also prove to be particularly helpful for teaching motor-memory tasks such as contact lens application and removal, which can be difficult to convey through written instructions.

MATERIALS & DESIGNS

No More Excuses Nearly gone are the days of excuses: Daily disposables are more expensive (read my prior posts on how they are equal or cheaper), they are not available in silicone hydrogels (we have several silicone hydrogel spheres, including toric, and multifocal options), and the axes do not go around the clock (you are right, we may be lacking in some plus powers and some –2.25D cyl powers, but that accounts for only a fraction of our patients). I venture to guess that 95% of our non-specialty contact lens patients can be fit into a silicone hydrogel daily disposable lens and that 99% of our patients can be fit into daily disposables.
To our industry friends, you keep innovating and pushing our progress, and we will keep fitting.
Elemental Composition at Silicone Hydrogel Contact Lens Surfaces
The objective of this study was to measure the outermost surface composition of 11 silicone hydrogel (SiHy) lenses using X-ray photoelectron spectroscopy (XPS) to understand differences in wettability and potential interactions within an ocular environment. The SiHy lenses tested included balafilcon A, lotrafilcon A, lotrafilcon B, senofilcon A, comfilcon A, and somofilcon A reusable two-week or monthly replacement lenses and delefilcon A, samfilcon A, narafilcon A, stenfilcon A, and somofilcon A daily disposable lenses.
All lenses were soaked for 24 hours in phosphate-buffered saline to remove all packaging solution and were dried under vacuum overnight before analysis. X-ray photoelectron spectroscopy measurements were performed at two take-off angles, 55° and 75°, to evaluate changes in elemental composition as a function of depth from the surface.
Detailed analysis of the XPS data revealed distinct differences in the chemical makeup of the different lens types. For all lenses, carbon, oxygen, and nitrogen were observed in varying quantities. In addition, fluorine was detected at the outermost surface region of comfilcon A (3.4%) and lotrafilcon A and B (< 0.5%). The silicon content of the near-surface region analyzed varied among lens types, ranging from a low of 1.6% (lotrafilcon B) to a high of 16.5% (comfilcon A). In most instances, silicon enrichment at the outermost surface was observed, resulting from differences in lens formulation and design.
The study authors found that lenses differed most in their surface silicon concentration, with lotrafilcon B and delefilcon A exhibiting the lowest silicon contents and comfilcon A exhibiting the highest. Silicon has hydrophobic properties, which, when found at the surface, may influence the wettability of the contact lenses and their interaction with the tear film and ocular tissues. Higher surface silicon contents have been previously correlated with adverse effects, such as enhanced lipid uptake, thus underscoring the importance of monitoring their presence.
