Protecting Sight #142: The magic washing machine. Phaco wound burns & PCO elimination. Leonardo’s Virgin of the Rocks.

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 – Hans Rosling: The magic washing machine. “What was the greatest invention of the industrial revolution? Hans Rosling makes the case for the washing machine. With newly designed graphics from Gapminder, Rosling shows us the magic that pops up when economic growth and electricity turn a boring wash day into an intellectual day of reading.” (

And what we said, my mother and me, “Thank you, industrialization. Thank you, steel mill. Thank you, power station. And thank you, chemical processing industry that gave us time to read books.” 

Hans Rosling (Ted Talk)

Brilliant and thought provoking.

2. Cataract Surgery – Uday Devgan MD – warning: phaco wound burn!. Dr. Devgan writes in part,”This is among the most important cataract surgery videos that you will see in your lifetime. Really. I have taught thousands of cataract surgeries to nearly 200 resident ophthalmologists over the past 20 years and I have only seen this complication a couple of times. But, make no mistake, this complication could happen to you!”

Issue cover for Volume 127, Issue 4

3. Journal – Elimination of Posterior Capsule Opacification. Marie-José Tassignon. Ophthalmology April 2020: S27-28.

The 2-page introductions to the landmark articles are superbly written.

4. Book Chapter – Leonardo da Vinci by Walter Isaacson. Chapter 15, “Virgin of the Rocks.” An elegant chapter which compares and contrasts the Louvre and London versions.
