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.

Since the turn of the century, we have presented annual overviews of contact lens prescribing trends in Contact Lens Spectrum. The work was initiated to help eyecare practitioners who are active in contact lenses to benchmark their fitting habits against their peers as well as to provide context to researchers in the field working on next-generation products. The database of lens fits collected over this period now exceeds 400,000, and the information has been collected across 71 markets.

In each targeted market, we supply survey forms and request that practitioners complete generic information about the first 10 contact lens fits conducted after receipt. This fundamental approach has remained unchanged since the first survey was conducted in the United Kingdom in 1996, with only minor changes to the form to account for new products becoming available on the market. For example, an option for “anti-myopia” (now termed “myopia control”) lenses was introduced in the 2011 survey to allow us to track developments in that area.

The distribution of the survey form varies. Some markets continue to use paper forms with a reply-paid envelope; others distribute and collect the same form via e-mail or a web-based questionnaire. The work is coordinated in each market by national coordinators who are listed as co-authors of this paper.

The survey forms request information about the age and sex of each contact lens patient fitted in addition to data about the material, design, replacement frequency, and wearing modality of the fitted lenses; anticipated weekly usage; and care system type. Each fit is weighted based on the estimated annualized number of fits for each practitioner. The data are finally collated at both the University of Manchester in the United Kingdom and at the University of Waterloo in Canada.

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 COVIDeyefacts.org — can help you and your family maintain the best vision while staying safe.
