After an initial pilot study the web based survey was distributed to all undergraduate ophthalmology teaching leads via an email link to a Bristol Online Survey webpage. Participants were given two months to respond to the questionnaire. Any respondents that had not replied by the complete by date were followed up and contacted via email to encourage a greater response rate. Responses were collated on the Bristol Online Survey website. Missing data was identified and a few individuals were contacted directly via email to clarify these answers to increase the data reliability.
