The number of incident cataract surgeries continues to increase at a steady rate, with the greatest number of surgeries performed in the most recent year analyzed, according to a study.
In a population-based extended study of medical records in Olmsted County, Minn., Mayo Clinic researchers merged 7 years of data from 2005 to 2011 with data from 1980 to 2004 to create a cataract registry spanning 3 decades.
In the most recent 7-year period, 8,012 cataract surgeries were performed on 5,725 patients, with the number of surgeries increasing significantly over the period and reaching a peak rate of 1,100 per 100,000 in 2011 (P < .001).
The rate of cataract surgeries in women increased over the 2005 to 2011 time span compared with the previous 7 years, but no significant change in the rate of increase was seen in men. The number of second-eye surgeries performed within 3 months of first-eye surgery at least doubled over the number performed in the previous 7 years (P <.001).
Large population-based studies in Sweden have shown a leveling off in the number of cataract surgeries performed, but the current study shows an increase in surgery rate.
“Our updated incidence data estimates changes in annual demand for cataract surgery and should prove useful in planning future health care spending and in ensuring adequate access to appropriate cataract treatment,” the study authors said.
