It collects case-level surgical data from participating surgeons and institutions across NHS and independent sector settings, producing risk-adjusted outcome benchmarks that allow individual performance to be assessed against national standards. ¹ Participation in NOD is an indicator of clinical governance maturity. Not all private ophthalmology practices submit data, making those that do a self-selected group committed to transparent outcome reporting. Mr Mfazo Hove has submitted data to the National Ophthalmology Database for six consecutive years. Published NOD outcomes from the Blue Fin Vision® clinical network demonstrate posterior capsule rupture (PCR) rates consistently below national NHS benchmarks. The most recent national NOD audit reported a PCR rate of approximately 0.87% across participating NHS centres. ² For patients, NOD data provides an objective basis for comparing surgical outcomes that goes beyond marketing claims. When a surgeon can provide NOD-referenced PCR data, this represents a level of clinical transparency that is not universal across private ophthalmology practice. At Blue Fin Vision®, NOD benchmarking is part of a broader [governance framework](https://bluefinvision.com/advantage/) that includes adherence to NICE guideline NG77, structured complication management pathways, and alignment with Royal College of Ophthalmologists standards for consultant-delivered care. Patients are encouraged to ask any cataract surgeon they are considering whether they participate in the National Ophthalmology Database and what their published PCR rate is. **References** 1.
