Childhood Myopia Epidemic Explained in New Podcast

CORE Clinical Scientist & Myopia Expert Dr. Debbie Jones Describes How the Global Issue is Affecting Canadian Families—and What Can be Done About It.

WATERLOO, ONTARIO, November 15, 2022—A new podcast designed for non-medical listeners explains the reasons behind the global childhood myopia epidemic and what that means for Canadian families. Featuring Dr. Debbie Jones, a clinical scientist from the Centre for Ocular Research & Education (CORE) and internationally known myopia expert, the 22-minute discussion is part of the Don’t Lose Sight interview series from the Canadian Association of Optometrists.

The episode is available on the series website, as well as through major podcast platforms including Spotify and Amazon Music.

Dr. Jones defines myopia—also referred to as nearsightedness—and how it can worsen as a child grows. Speaking with podcast host Denise Balch from Connex Health, she describes the associated risks for more severe vision impairment later in life as a potential consequence.

While half the world’s population is projected to be myopic by 2050, the crisis is already evident in Canada. Dr. Jones notes that recent work showed a 30% prevalence among 11- to 13-year-olds in the Waterloo-Kitchener region. Remarkably, one-third of those children’s caregivers were unaware of the problem until the research project uncovered the condition.

Far from being insurmountable, preventing or delaying the onset of myopia is possible, says Dr. Jones. She recommends that group benefits administrators and wellness coordinators help their employees consider outdoor time and screen time plans for their children. She also describes a range of therapies that are available to slow myopia progression, including specialized contact lenses and eyeglasses, as well as eye drops.

Balch and Dr. Jones encourage parents to have their children’s eyes examined regularly by an optometrist, so that problems can be identified as early as possible.

Dr. Jones concentrates her clinical work in pediatric optometry and research in myopia control. Trained in the UK, she is currently a clinical professor at the School of Optometry and Vision Science at the University of Waterloo, where she has been a faculty member for more than two decades. She was formerly in private practice and has published articles in optometric journals and regularly presents at optometric conferences worldwide. Dr. Jones is a Fellow of the British College of Optometrists, the British Contact Lens Association and of the American Academy of Optometry.

CORE Scientists Develop Low-Cost 3D Bio-Printing Method for Ophthalmic Drug Delivery Research

WATERLOO, Ontario, August 22, 2022—An ingenious development from the Centre for Ocular Research & Education (CORE) has unlocked a path to faster, inexpensive eye model creation for use in ophthalmic drug research. Using a commercially available masked stereolithography printer (mSLA) retrofitted with humidity and temperature controls, plus a new gelatin-based ink formulation, a team of scientists 3D bio-printed an in vitro eye model in under three hours.

The resulting “eye” included aqueous, vitreous, and blood chambers, a blood outlet/inlet, aqueous and vitreous outlets, and a 500μm-thick cornea—absent any artificial support structures. Phosphate-buffered saline was used as an aqueous and vitreous humor mimic in the corresponding drug delivery study, which measured contact lens-delivered dye transfer in each chamber and channel.

A summary of the novel methodology, Developing a Novel In Vitro Eye Model Using 3D Bioprinting for Drug Delivery Studies (Phan C, Wulff D, Garg P, Jones L), is now published in Investigative Ophthalmology & Visual Science, an ARVO journal.

“3D bio-printing is still in its nascent stages because it’s slow, not scalable for large-scale projects, and extremely expensive. This severely limits its use for high-throughput applications in many academic and research settings,” said Chau-Minh Phan, research assistant professor at CORE. “Our work shows the promise of an alternative approach, with much faster layer-based printing at a significantly lower cost. We believe this is a starting point for developing enhanced 3D eye models to test drug release kinetics of various devices and formulations.”

The team’s future work will focus on adding diffusion barriers to better simulate drug diffusion through ocular tissues, experimenting with co-polymer inks to extend each model’s lifespan, and fine-tuning physiological dimensions.

This latest innovation follows CORE’s creation of other sophisticated eye models in recent years for ocular testing, virtual and augmented reality applications validation, and clinical education. Its OcuBlink affiliate operates autonomously, while using CORE staffing, counsel, and laboratories.

CORE Publishes Resource on Neuropathic Ocular Pain; Says Increased Understanding Essential to Patient Care

WATERLOO, Ontario, July 6, 2022—In response to fast-emerging clinical interest about neuropathic ocular pain, the Centre for Ocular Research & Education (CORE) is taking action to create more understanding of the issue among the global eye care community.

“While most practitioners commonly treat physiological pain, which stems from structural damage or stimuli, they’re often less confident in their abilities to diagnose and address neuropathic ocular pain, which results from nerve signal deficiency or nerve damage,” said Alex Hui, OD, PhD, FAAO, head of BioSciences for CORE. “Greater awareness, understanding, and consideration of neuropathic pain as part of the diagnosis and differential diagnosis process, plus familiarity with options to help patients navigate the challenge, is essential for evolved care.”

In primary eye care settings, neuropathic corneal pain is most commonly observed in patients experiencing dry eye, having herpetic corneal infection, and following kerato-refractive or cataract surgery. While the TFOS DEWS and DEWS II reports have elevated the issue, there is still widespread misinterpretation of neuropathic pain as physiological discomfort.

As part of its efforts to educate practitioners, CORE has dedicated Issue 66 of Contact Lens Update to the issue. The bi-monthly publication is available at no charge by visiting ContactLensUpdate.com.

Anat Galor

Anat Galor, staff physician at the Miami VA and associate professor of Ophthalmology at the Bascom Palmer Eye Institute, University of Miami, along with recent medical school graduate, Sneh Patel, contribute the editorial. The authors provide a systematic overview of neuropathic pain and its manifestation in the eye. A comprehensive summary of the state of the art in respect to the diagnoses and treatment of ocular neuropathic pain rounds off the editorial.

Jessica Steen

Jessica Steen, assistant professor at Nova Southeastern Univiersity College of Optometry, provides the feature article that highlights a retrospective case-series assessing post-LASIK neuropathic pain. These findings demonstrate the importance of careful patient selection, assessment of risk factors and post-operative evaluation in preventing the development of neuropathic corneal pain in those who undergo LASIK.

Richard Maharaj

Prism Eye Institute’s Richard Maharaj shares his expertise in the form of a clinical insight.  A comprehensive case-report outlines the evaluation, treatment, and follow-up of a patient with mild dry-eye and post-LASIK neuropathic pain. Maharaj demonstrates how a thorough assessment, multimodal treatment algorithm, and collaboration between eye care practitioners and other health care providers, results in greatly improved quality of life in those affected by neuropathic ocular pain.

Pedram Hamrah

The conference highlight is shared by Pedram Hamrah, interim chairman of the Department of Ophthalmology and Professor of Ophthalmology at Tufts University School of Medicine. This poster demonstrates the similarity in morphological changes of the corneal nerves in symptomatic and intolerant contact lens wearers, and those with neuropathic corneal pain. The findings from this study suggest a neurosensory component to contact lens discomfort.

CORE Study Shows Importance of Rub and Rinse Regimen for Coronavirus Removal from Contact Lens Materials

New Research Published in Contact Lens and Anterior Eye;
Illustrates Differences Between Oxidative and Non-Oxidative Lens Care Systems  

 WATERLOO, ONTARIO, June 9, 2022—A new study conducted by the University of Waterloo Department of Chemical Engineering and the Centre for Ocular Research & Education (CORE) has determined that human coronaviruses can easily be removed from contact lens surfaces, although regimen matters depending on the type of lens care solution. Most notably, rub and rinse steps are crucial for non-oxidative systems, while products containing hydrogen peroxide and povidone-iodine removed contaminants through soaking alone.

The impact of a rub and rinse regimen on removal of human coronaviruses from contemporary contact lens materials (Nogueira C, et al) is in press from Contact Lens and Anterior Eye, the peer review journal of the British Contact Lens Association.

While an ocular pathway has not been demonstrated to be a primary route of entry for SARS-CoV-2, the ongoing COVID-19 pandemic has raised awareness about physical virus transmission via hands and fingers. However, there has been limited data regarding the attachment of viruses, particularly coronaviruses, across lens materials and the ability of contemporary contact lens care products to inactivate such.

To assess attachment bonds, researchers selected two seasonal human coronaviruses, HCoV-229E and HCoV-OC43 as surrogates for SARS-CoV-2, allowing for less pathogenicity while being in the same virus family with similar structures. Eight soft contact lens materials (including silicone hydrogels and hydrogels) and four RGP contact lens base materials (with and without a hydrophilic coating) were contaminated then soaked in a phosphate-buffered saline. Although viral particles were recovered when the lenses were removed from the passive saline soak, no detectable virus remained when the lenses were subjected to a single rinse, double rinse, or rub-and-rinse treatments.

Since a simple saline rinse step alone removed both virus types from all materials, two representative soft lens materials (one hydrogel and one silicone hydrogel) were chosen to evaluate care system efficacy for elimination of HCoV-229E. Investigators selected four representative contact lens care products (two oxidative and two non-oxidative). Both oxidative disinfection systems reduced the number of infectious viral particles that adhered to each material below the limit of quantification through soaking alone. The non-oxidative disinfection systems required a rub and rinse step to do the same.

“Our results indicated that human coronaviruses bind quite loosely to contact lens materials, which should provide peace of mind for the eye care community and wearers, as long as proper care occurs,” said Lyndon Jones, PhD, DSc, FCOptom, a paper co-author and CORE’s director. “Practitioners and manufacturers need to continue emphasizing the importance of following disinfection regimens, especially ensuring that a rub and rise step occurs prior to overnight disinfection when using non-oxidative systems.”

The complete paper and supplementary data are available at no cost from Contact Lens and Anterior eye at https://doi.org/10.1016/j.clae.2022.101719. The study was funded by Ophtecs Corp.

McDougall Communications & CORE Honored for Mask-Associated Dry Eye Work

Rochester, N.Y., May 23, 2022—For the third time in five years, McDougall Communications and the Centre for Ocular Research & Education (CORE) have received the global public relations industry’s top campaign honor—a Public Relations Society of America Silver Anvil Award. The latest recognition resulted from efforts to raise awareness among medical professionals and consumers about increases in dry eye symptoms during the COVID-19 pandemic, as well as identifying steps to alleviate the discomfort.

The 18-month program is credited with drawing widespread attention to a new condition called MADE, or mask-associated dry eye. This initiative spurred more than 2,500 mainstream news reports on six continents, plus broad coverage by ophthalmic industry journalists. Eye care practitioners worldwide rapidly took note and adopted CORE’s guidance, providing much-appreciated patient relief.

A CORE-bylined feature story written as part of the program was also awarded a Bronze Anvil Award of Commendation, which are given to the industry’s best tactics.

Since 1944, the Anvil Awards have been presented to organizations that successfully address challenging issues with exemplary professional skill, creativity, and resourcefulness. They are often referred to as the Oscars of the public relations profession, owing to their stringent judging process and candidates from around the world.

McDougall Communications has been awarded multiple Anvils in recent years, spanning a range of clients, programs, and categories. For its work with CORE, the firm received the Silver Anvil in 2018 for a launch of the organization’s new brand, followed by a Bronze Anvil Award of Commendation in 2019 for digital innovation. In 2021, the McDougall and CORE received two additional Silver Anvils plus an Award of Excellence for spearheading a worldwide crisis response to COVID-19 misinformation about contact lens wear.

Other 2022 Anvil honorees included St. Jude Children’s Research Hospital, Delta Airlines, UPS, Royal Caribbean Group, and the Minnesota Attorney General’s Office for communications central to its prosecution of Derek Chauvin. The awards were presented on May 19 during a ceremony at Manhattan’s Edison Ballroom.

“It’s a privilege to partner with CORE on some of the timeliest issues in ocular health, helping eye care practitioners and the public gain access to reliable, accurate, and relevant information that affects vision. Congratulations to that incredible team of researchers, clinicians, and educators—and to all of this year’s Anvil winners” said Mike McDougall, APR, Fellow PRSA, the firm’s president.
