Description of registry

The National Quality Registry for Cataracts was originally established to monitor the effects of the introduction of the limited waiting time guarantee for patients waiting for cataract operations.

The core registry focuses on demographics, waiting times for surgery and visual function at the time of surgery. The registry has been expanded to include outcome data, perceived benefit of the surgery and the prevalence of post-operative endophthalmitis (infection inside the eye). A key objective is to document differences in the country in terms of availability and outcome.


All patients who have undergone cataract surgery in Sweden are included in the registry. The procedure must have been completed for registration to be possible. The aim of the registry is for all clinics in the country (both public and private) to report their completed cataract surgeries.
