The Cataract National Data Set provides a long-established standard for recording cataract care in a consistent way. It supports routine data collection across assessment, biometry, anaesthetic care, surgery and follow-up, helping services compare outcomes fairly and use data for audit and quality improvement. The current workbook reflects a long development history and remains central to standardised electronic collection for cataract services.
An accompanhying document explains revisions to The Royal College of Ophthalmologists cataract refractive minimum dataset. It sets out the rationale for presenting expected refractive outcomes as spherocylinders rather than spherical equivalents alone, providing surgeons with more clinically useful information when selecting intraocular lenses and planning surgery.
The guidance describes how refractive outcomes can be calculated and displayed within electronic medical record systems, enabling surgeons to assess expected outcomes more accurately and consider the potential effects of surgical modifications. It also highlights the value of spherocylindrical outcome reporting for evaluating refractive results, identifying outliers and supporting continuous improvement in cataract surgery outcomes.
Since 2010 a subset of this data set has formed the basis for the National Cataract Audit. The audit has tracked outcomes since 2010 and has helped build a strong national picture of surgical safety and outcomes.
