The aim of this report was to investigate the impact of the introduction of EyeSi training on the PCR rates for operations performed by first and second year trainees over seven consec- utive National Health Service (NHS) years. The study utilised cataract surgery data from the Royal College of Ophthalmol- ogists’ National Ophthalmology Database (RCOphth NOD) audit. METHODS The RCOphth NOD was established under the auspices of the Royal College of Ophthalmologists in 2010 to collate pseud- onymised data collected as a byproduct of routine clinical care for the purposes of national audit. In 2014, the RCOphth NOD audit was commissioned to perform the National Ophthal- mology Database Audit (NOA) by the Healthcare Quality Improvement Partnership ( www. nodaudit. org. uk). The NOA receives data collected on electronic medical record (EMR) systems and in-house databases from centres performing NHS funded cataract surgery in England and Cymru, including NHS funded operations performed in independent treatment centres. The study time period concerns NOA eligible cataract oper- ations performed between 1 April 2009 and 31 March 2016 which corresponds to seven consecutive NHS years, where the first year includes the operations before the introduction of standard EyeSi training in 2010. Using the RCOphth NOD, 29 centres were identified with the centres first cataract surgery in the study period performed between 2009 and 2012, and where Figure 1 An EyeSi surgical simulator (VR Magic). each centre had at least 50 operations performed by first and second year trainee surgeons. The centres were contacted to determine when they intro- procedure, apart from creating corneal incisions, and the auto- duced EyeSi training and which other hospitals in their region mated assessment categorises performance in five domains: had access to their EyeSi. Of the 29 centres, 23 had either target achievement, efficiency, instrument utilisation, tissue purchased or had access to an EyeSi between 2010 and 2016 damage and microscope usage. and six centres had no access to an EyeSi during this period.

Centres with access to an EyeSi were further categorised as access on site or off site. An eligible cataract operation was defined according to the criteria used for eligibility in the National Ophthalmology Data- base Audit. Only operations performed by a first or second year trainee (ST1, ST2 or a Senior House Officer (SHO)) were included. on 5 June 2019 by guest. Protected copyright. All data were recorded on the Medisoft electronic record system (Medisoft Ophthalmology, Medisoft Limited, Leeds, UK, www. medisoft. co. uk) which mandates the recording of intra- operative complications. PCR was defined as posterior capsule rupture with or without vitreous prolapse or zonule rupture with vitreous prolapse. Statistical comparisons used χ2 tests and all analysis was performed using STATA V.14. Patient and public involvement Patients, carers and members of the public were not directly involved with this study.
