Protecting Sight Daily Learning #20: One Ted Talk, cataract surgery, journal article, and book chapter. The subtleties of cataract surgery and Moby Dick. #ProtectingSight

Welcome to day #20 of my daily learning journal. My goal is to watch one Ted Talk and one cataract surgery each day. In addition, I 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 = Frederick Balagadde – Bio-lab on a microchip (April 2010)- “Drugs alone can’t stop disease in sub-Saharan Africa: We need diagnostic tools to match. TED Senior Fellow Frederick Balagadde shows how we can multiply the power and availability of an unwieldy, expensive diagnostic lab — by miniaturizing it to the size of a chip.” (

“TED Senior Fellow Frederick Balagadde invented the micro-chemostat, a first-of-its-kind, dime-sized piece of transparent plastic that can orchestrate the behavior of living cells.” (

This was a “Surprise me!” Ted Talk pick. Excellent 6-minute talk.

2. Cataract Surgery – Uday Devgan MD – The subtleties of cataract surgery – Another superb post by Uday. It’s less than 4 minutes and worth watching many times.

4. Book Chapter – Herman Melville – Moby Dick. I love the free podcasts available by Listened to Chapter 4-16. Starting to review Sparknotes to appreciate the subtleties in the narration.

Ophthalmology colleagues, you may enjoy Melville’s comment in Chapter 1, “Were Niagara but a cataract of sand, would you travel your thousand miles to see it?” (
