Abstract Details


To prospectively audit cataract surgery at a busy teaching hospital eye department during June 2013 and compare this with data collected in 2011.


St Paul's Eye Unit, Royal Liverpool Hospital - a teaching hospital and tertiary eye unit


Data collected prospectively during June 2013 was compared with data collected in June 2011. Outcome factors included age, gender, visual acuity, type of lens, predicted spherical equivalent, biometry type, surgeon grade, complications type, and if patient had a guarded prognosis. Exclusions were cataract surgery combined with other procedures (such as removal of oil, penetrating keratoplasty, deep sclerectomy) and operations with toric/multifocal intraocular lens implantation.


Of the total number of procedures eligible for inclusion in the audit, the response rate was 85%. There were fewer complication rates as a percentage of procedures in 2013 (7.3% compared to 11.5%). Complication rates did not statistically differ between consultants versus non-consultant grades in either 2011 (p=0.99) or 2013 (p=0.60). Ages and gender bias was similar between 2011 and 2013. Non-contact biometry was increasingly used compared to A-scan biometry. A widely available single piece, UV-blocking injectable lens was the preferred type of intraocular lens. There was a tendency towards selecting a slight myopic post-operative spherical equivalent on average, with some hyperopic/myopic outliers. Number of procedures by consultants increased in 2013.


Between 2011 and 2013, complication rates following cataract surgery decreased. There was no statistical difference in complication rates between surgeons at consultant level and trainees, persisting from 2011 to 2013. FINANCIAL INTEREST: NONE
