Very useful data on an important issue, given the high proportion of the population using contact lenses (Swanson MW, 2012). On the issue of the level of individual risk, readers might find a review of large-scale epidemiological studies helpful (Stapleton F, 2013).

The authors stress the importance of good lens hygiene to reduce the risk of infection. That's a critical issue, and people may well over-estimate the adequacy of their own lens care (Bui TH, 2010). Given the increased risk of extended wear (rising from 2-4 per 10,000 for daily use to about 20 for extended wear Stapleton F, 2013), users being better informed about reduced wear as a way of lessening risks may also help (covered along with social and historical aspects in this blog post.)
