Sometimes you need to stand back and look at such studies to realise that there are other explanations which the paper’s contributors had not even considered.
The first one that occurs to me is that all the women I know on HRT have a very different attitude to health. They are extremely proactive in seeking and securing medical help to live the best lives they can. They have already shown that by opting for HRT so when they feel their sight is deteriorating I’m guessing they are highly effective in ensuring they have their cataracts removed.
Most of us get cataracts, but some of us are better at ensuring they get treated.
So women who don't use HRT don't care about their health??? Actually exactly the opposite is true women who reject HRT tend to research other solutions for their symptoms, use activities such as yoga to help are conscious of their diet, ask for medication to deal with specific problems such as osteoporosis and are generally very health conscious.
As for the assertion about cataracts of course they are treatable and saying someone seeks treatment early is ridiculous. Treatment depends on the ophthalmologist deciding the cataract is at the right stage, you can't just demand it.
