Do you know what this is?
If you are an optometrist you should.
If you are examining the eyes of a 70 year old man whose vision has been worsening for the past 10 years,
you should know what it is.
You should recognize a cataract when you see one and know that it is treatable.
Treated not by changing the lenses of your patient’s eyeglasses
but by replacing the lenses in your patient’s eyes.
Fortunately for the man in question his optometrist retired and he acquired a new optometrist.
One that knew about the latest research and practices.
(N.B. For the sake of future patients, I hope the new optometrist remains current).
There are things that teachers do that are, and always have been good practice.
Education research and brain research show that many of our past practices are good.
But the research also shows that there are somethings we should stop doing
there are somethings we should start doing.
And to know the difference we have to stay current.
Otherwise we are in danger of malpractice.
