With contributions from global experts in this subject area, this issue focusses on corneal infiltrative events (CIEs) associated with soft contact lens wear, examining their incidence, risk factors and the steps that can be taken in practice to advise patients on reducing their chance of developing them. Loretta Szczotka-Flynn has written a comprehensive editorial which addresses all of these areas, including a review of the associations between mucin ball formation and CIEs. Robin Chalmers not only summarises key points from Kelsey Steele’s recent review paper on the epidemiology of CIEs, but also provides several helpful pieces of advice for practitioners. Future work in this field is highlighted with Debarun Dutta’s conference abstract which examines the effect of antimicrobial contact lenses on the incidence of CIEs in extended wear. The clinical insight in this issue is a factsheet containing all the relevant figures on CIE incidence and risk factors, and is intended to be downloaded for use by practitioners as a quick reference tool.

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.
