In the study, there were 74,044 women who had been identified with a cataract and within that group 41,735 had undergone cataract surgery during the study time period.
The results showed that of those in the group who had cataract surgery, the mortality – or death – rate was 1.52 deaths per 100 person years. That means that in any given year if you took 100 women who had cataract surgery about 1.52 died in that year. The mortality rate in the women who did not have cataract surgery was 2.56 deaths per 100 person years. Those numbers mean that women who had cataract surgery were 40% LESS LIKELY to die in any given year than […]
