International contact lens prescribing in 2020 Contact Lens Spectrum 2021;36, January: 26-32 [ Show Abstract ]

This article is our 20th consecutive annual report of international contact lens prescribing for Contact Lens Spectrum. The premise of the work is simple. As an alternative to asking a cross section of contact lens wearers about the lenses that they use and the basis on which the lenses are worn, we move upstream in the process and directly survey those who are fitting contact lenses in numerous markets around the world. This presents a more “leading edge” indicator of contact lens fitting habits; the lenses fitted today are those sold tomorrow. The aim here is to provide summary information for colleagues in clinical practice, industry, and academia about contact lens prescribing behaviors to inform their patient management, research and development, and educational curricula, respectively.

Ng AY, Yang M. Why you shouldn’t neglect eye care during the pandemic The Conversation 2021;March 7 [ Show Abstract ]

Since COVID-19 emerged, access to eye care has continued to change. Lockdowns and concerns about virus exposure have caused people of all ages to cancel and delay routine appointments, raising red flags among eye-care professionals. As the pandemic continues into its second year, can ocular health be neglected any longer?

Our team of optometrists and clinical scientists at the Centre for Ocular Research & Education (CORE) hear the confusion and concerns about people’s eyes during COVID-19. Addressing the most common questions — many of which we keep up to date at — can help you and your family maintain the best vision while staying safe.

Patel K, Walsh K. Soft toric contact lenses: Aligning patient expectations and eye care professional attitudes Optician 2021, March: 32-36 [ Show Abstract ]

In this article Krupa Patel and Karen Walsh examine the expectations around soft toric lenses from both the practitioner and patient’s point of view. It serves as a timely review of current toric fitting practices and how they relate to the prevalence of astigmatism, highlighting a number of opportunities for enhancing patient satisfaction and increasing practice revenue (C77594, one distance learning CET point suitable for optometrists, contact lens opticians and dispensing opticians).
Some simple facts help set the scene for this global review. It has been established that modern soft toric contact lenses are as quick and simple to fit as spherical lenses, with good visual outcomes and rotational stability across many visual tasks. However, when 400 eye care professionals (ECPs) in the US were asked, only around half agreed soft torics are as easy to fit as the equivalent spherical lens (49%), and that they have excellent rotational recovery (55%). How does this disparity between reported product performance and practitioner attitude influence fitting practices? Ultimately, what is the impact on patients, and how close does current practice come to meeting their

Walsh K. BCLA CLEAR Summary 2021 [ Show Abstract ]

The BCLA Contact Lens Evidence-based Academic Report (CLEAR) totals more than 300 pages across 11 papers. Coordinated by 10 committee chairs, written by 102 authors based in 16 countries, it was published in March 2021 and is available here.

BCLA CLEAR sets the standard to which eye care professionals (ECPs) can refer for the latest information in the contact lens field whilst also highlighting opportunities for future research. This summary draws on key points from the reports to help inform evidence-based practice.

Walsh K, Jones L. Covid-19 and contact lenses: Keeping it simple in the ‘new normal’ Optician 2021, March: 25-30 [ Show Abstract ]

Karen Walsh and Professor Lyndon Jones examine how Covid-19 has affected routine contact lens practice and what that means for both eye care practitioners and their patients (C77595, one distance learning CET point suitable for optometrists, contact lens opticians and dispensing opticians).

In the first quarter of 2020, routine clinical eye care underwent a temporary cessation in most regions around the world due to the coronavirus pandemic. Optometric practice is now predominantly back up and running, albeit with the occasional return to a higher alert level as the infection rates in countries ebb and flow over time. The demands
of working in a world with Covid-19 have necessitated changes to how routine practice is conducted. As a result, the attitudes and needs of eye care practitioners (ECPs) and patients related to eye care in general, and contact lenses (CLs) in particular, may have altered. Within this new shape of optometric practice, the question of where CL practice fits naturally arises. While aftercare for the routine assessment and resupply of existing wearers may seem acceptable, how does the profession approach the option of new fits and upgrades? Given the wider challenges faced by practitioners, is this really the time to focus on such areas? Is it even ‘safe’ to fit CL now, given the close contact required? However, looking at it from a different point of view, are there in fact opportunities arising from the changes dictated by Covid-19 that could be beneficial for CL practice? This article reviews the recommendations
for safe CL practice, looks at their relevance for both practitioners and patients, and addresses how CL can be accommodated into the daily clinic routine as easily as possible.

Das Jahr 2020, in dem die Corona-Pandemie begann, hat die gesamte Weltgemeinschaft und damit das Leben jedes einzelnen Menschen verändert. Folglich sind die Auswirkungen der Pandemie auch in der augenoptischen Branche zu spüren. Die Autoren Karen Walsh, MCOptom und PGDip, und Lyndon Jones, DSc und FCOptom, ziehen Bilanz.

Walsh K, Jones L. COVID-19: A year in review and the impact on CL practice Contact Lens Spectrum 2021;36, February: E1-E6 [ Show Abstract ]

For everyone involved in eye care, 2020 was going to be a special year. The numerous “20/20” puns and articles circulating in January were full of hope and future-gazing. No one could have predicted the direction that the year would take and its resulting impact on the world at large and, for this audience specifically, on the delivery of routine contact lens care. As the end of this unprecedented year has finally come to pass, it feels right to pause and reflect on the last 12 months, to examine the journey that the profession has taken, and to summarize the situation. This article reviews what the profession has learned and asks whether enough is known to successfully navigate the months and years ahead. With no small amount of irony and a large nod to those aforementioned puns, does being approximately one year into the pandemic result in having a useful amount of “20/20 hindsight”?

Walsh K, Sulley A. Soft toric lens fitting practices not meeting patient needs Optometry Times Journal 2021;13, 2: 34-37 [ Show Abstract ]

The inclusion of astigmatic correction in spectacles is common practice. Outside of the need to reduce a high or previously uncorrected astigmatism to ease adaption, eyecare professionals (ECPs) routinely prescribe the full toric correction in spectacles. Historically, the lack of availability of consistently performing, comfortable soft toric contact lens designs resulted in different prescribing practices for astigmats compared to those wearing spectacles, with spherical lenses often recommended over toric lenses for low to moderate levels of astigmatism.

Modern soft toric designs are significantly different from early non-planned replacement versions of 20 or more years ago. Their overall performance—which includes ease of fitting, comfort, rotational stability, vision performance, and consistent manufacturing in a range of designs and materials—enables them to be fit successfully to a wide range of astigmatic patients.

This review provides an overview of current soft toric prescribing, comparing and contrasting different fitting practices around the globe, and explores patient expectations and the opportunities that exist to meet their needs.
