This review summarizes data collected by the Swedish National Cataract Register, which now contains data pertaining to more than a million cataract surgery procedures, representing 95.6% of the surgeries performed in Sweden during 1992-2009. During this period, the rate of cataract surgery rose from 4.47 to 9.00 per 1000 inhabitants. The mean patient age increased until 1999 but has slowly decreased since then. Preoperative visual acuity has risen steadily. The distribution between the sexes was stable until 2000, after which the proportion of women slowly decreased. Registration of subjective benefit has brought new knowledge regarding indications and expectations. An improved questionnaire, Catquest-9SF has been used since 2008. The outcome register generally shows good results from the surgery. Endophthalmitis has decreased from 0.10% to below 0.040%.
