Solution induced corneal staining (SICS) has been documented for nearly twenty years, and our understanding of the mechanism by which it occurs and its clinical significance has evolved over time. This issue of contact lens update reviews this journey of understanding, sharing some novel new work, and a factsheet for practitioners own reference. Eric Papas has written a fascinating editorial describing how our appreciation of SICS has changed over time, concluding with some present day evidence. David McCanna reviews Tahmina Khan’s in vitro work which examines the mechanism of fluorescein uptake into cells, and how this is modulated by a particular surfactant found in some MPS. The conference highlight is Tahmina Khan’s own poster outlining the work referenced in her paper. Finally, a new SICS factsheet is available for practitioners to download, providing a summary of key information about SICS along with advice on how to deal with it in practice.

In February 2019, the International Myopia Institute published a series of reports designed to address the issues of myopia, the management of myopia in practice, to review myopia research to date, along with understanding how best to advance research in the future. This special issue of contact lens update reviews and summarises each report. Kate Gifford’s editorial provides an overview of the whole initiative, with members from CORE’s clinical team summarising the white papers. A recent poster from Noel Brennan is shared, and a factsheet is available to download, for use by practitioners to help implement myopia management in practice.

The eyelids play an important role in contact lens wear. This edition reviews the interactions which occur between contact lenses and the eyelids, lid margins and Meibomian glands. Sowjanya Siddireddy’s editorial is a comprehensive review of our current understanding about the role of the eyelids in contact lens wear, and how they contribute to contact lens discomfort. Will Ngo reviews Siddireddy’s own paper on contact lens discomfort, the eyelids and tear film which concludes that significant differences in the eyelid margin and tear film exist between symptomatic and asymptomatic contact lens wearers. Andrew Pucker presented the results of a study examining the association between the health of the Meibomian glands and contact lens drop out at the American Academy of Optometry meeting in November 2018. The abstract of that presentation is shared in this edition. Brian Tompkins and Keyur Patel provide a practitioner view in the clinical insight section, sharing why they pay such close attention to the condition of the eyelids in their contact lens patients, along with the series of clinical assessments they perform.

Do commonly held beliefs surrounding the fitting of soft contact lenses limit fitting practices? This edition of Contact Lens Update tackles three common myths, reviewing the evidence and making recommendations for use in practice. Karen Walsh’s editorial takes a look at the numbers of contact lens wearers, reasons for drop out and overall opportunity for growth within the sector. Ultimately asking the question “how may long-held beliefs affect fitting behavior”? Lyndon Jones’ feature article reviews the evidence surrounding the fitting of daily disposable silicone hydrogels, and addresses the barriers that exist which prevent these lenses being recommended more routinely. Jill Woods addresses soft multifocal lenses, examining whether overall success rates and patient satisfaction are worth the effort of fitting. The final myth, tackled by Karen Walsh, concerns the need to fit low astigmats with soft toric rather than spherical contact lenses.
- Editorial - Myth or Reality?
- Feature Article - Myth 1: Daily Disposable Silicone Hydrogels – Necessary or Not?
- Conference Highlights - Myth 2: Fitting soft multifocal lenses is complex, takes up a lot of chair time and never meets patient needs
- Clinical Insight - Myth 3: It is not worth correcting low astigmats with toric contact lenses
