Will Having Cataract Surgery Help You Live Longer?

August 23, 2018

This is a study that I love because it can teach us something about reaching a conclusion from a large population sampling.


The study was published in a high quality journal, JAMA Ophthalmology. 74,000 women with cataracts were followed. 42,000 had cataract surgery and were followed for up to 20 years. They found that the group that had cataract surgery had a 60% lower mortality from all causes.


It would be easy to jump to the conclusion that removing cataracts  will somehow give you longevity and even though it was a large sampling it did not take into consideration many other factors. The least is that those who had cataract surgery may have been healthier and may have taken better care of themselves in general.


The bottom line for our readers is to not believe everything that you read concerning matters of health. In fact this is true in general for all subjects. The famous American comedian Will Rogers was fond of saying “Believe nothing that you hear and only half of what you see.” This is as true now as it was 70 years ago.
