Protecting Sight #37: Confidence is the necessary spark before everything that follows. Glaucoma patients see the LiGHT with SLT.

Welcome to day #37 of 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 – Brittany Packnett – How to build your confidence — and spark it in others. ” ‘Confidence is the necessary spark before everything that follows,’ says educator and activist Brittany Packnett. In an inspiring talk, she shares three ways to crack the code of confidence — and her dream for a world where revolutionary confidence helps turn our most ambitious dreams into reality.” (

This was a Ted Talk recommendation (via email). If you watch Ted Talks on, you can click on “Transcript” to see the text. If you click on the text (on a desktop), a video clip for that portion of the talk appears.

Packnett’s pearls are wonderful and I’ve sent along to my nieces and nephews to watch.

2A. Cataract Surgery – Uday Devgan MD – Complete Cataract Case: a very special case. Unedited cases are among my favorites.

3A. Journal – Selective laser trabeculoplasty versus eye drops for first-line treatment of ocular hypertension and glaucoma (LiGHT): a multicentre randomised controlled trial. Gus Gazzard et. al on behalf of the LiGHT Trial Study Group. Lancet 2019; 393: 1505–16. April 13, 2019.

I saw Malik Kahook MD’s twitter post today and decided to revisit this Lancet article. Would recommend the original article and both of Dr. Kahook’s resources below.

3C. LiGHT Study: 1 Slide in 5 Minutes  (Malik Y. Kahook MD) (Youtube)

4. Book Chapter – Herman Melville – Moby Dick. Listened to Chapters 105-108 via See also Sparknotes (narration) and Gutenberg (book text).

See Protecting Sight Daily Learning posts here.

Please send me feedback. Would appreciate suggestions of Ted Talks, cataract videos, and journal articles to learn from and share.

5. (BONUS) I discovered Shane Parrish’s blog, The Knowledge Project, a few years ago. My own blog posts are inspired by his weekly newsletter (Brain Food). I highly recommend the clip below on breaking bad habits. For me, a “bad habit” was watching Sopranos, Seinfeld, and Everybody Loves Raymond video clips on YouTube! (Check out Farnam Street here).
