Protecting Sight #108: The psychology of inequality and political division. Aspirating the epi-nucleus, ganglion cell complex thickness, macular vessel density loss, and A Passage to India.

Welcome to my daily learning journal. My daily goal is to watch one Ted Talk and one cataract surgery. I also plan to read one journal article and read/listen to a book chapter, short story or significant work.

Here’s today’s list:

1. Ted Talk – Keith Payne – The psychology of inequality and political division. ” ‘If we want to fix our politics, we have to do something about inequality,’ says social psychologist Keith Payne. Showing how economic inequality changes the way people see and behave towards one another, Payne helps explain the rise of the political polarization that’s slicing up society — and challenges us to think twice the next time we dismiss someone for the sake of politics.” (

An excellent new Ted Talk. I enjoyed Professor Payne’s story (I was a financial aid kid also!) and his observations are most timely.

“The next time you’re tempted to dismiss someone who disagrees with you as an idiot, think about the tailwinds that helped you get where you are. What lucky breaks did you get that might have turned out differently? What helping hands are you grateful for?”

2. Cataract Surgery – Uday Devgan MD – easily aspirating the epi-nucleus. Dr. Devgan writes, “The key to aspirating the epi-nucleus with the phaco probe is to use the second hand and the chopper instrument to flip up the epi-nuclear shell while protecting the posterior capsule. I use the same phaco machine settings as my phaco chop mode and then just titrate the vacuum and flow levels with the foot pedal control.”
