Protecting Sight #48: The Opposites Game. Pseudoexfoliation and the risk of dislocated IOLs. Tom Sawyer’s hunt for treasure & dramatic ending.

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 – Brendan Constantine: The Opposites Game. “A classroom erupts into a war of words as students grapple with a seemingly simple prompt: what is the opposite of a gun? This animation is part of the TED-Ed series, ‘There’s a Poem for That,’ which features animated interpretations of poems both old and new that give language to some of life’s biggest feelings. [A TED-Ed Production, a film by Anna Samo + Lisa LaBracio, poem by Brendan Constantine, poem performed by Brendan Constantine, sound Design by Weston Fonger, animation & Design by Anna Samo + Lisa LaBracio, animation Produced by Gerta Xhelo].” (

This is a TED-Ed production. I tend to prefer Ted Talks in front of an audience (shying away from the COVID-inspired Zoom chats). This Ted-Ed talk is 4 minutes, fast paced, and worth a watch.

2. Cataract Surgery – Richard Mackool MD – Episode 7: Dense Brunescent Nuclear Cataract with Pseudoexfoliation. “An 87 year old patient presents with a dense brunescent nuclear cataract, pseudoexfoliation and a central corneal dry spot with opacification. Enhancing my visualization is key, as is being able to constantly visualize the edge of the anterior capsule during phacoemulsification. The use of my second instrument to protect the posterior capsule is also discussed.”

Dr. Mackool’s videos are filled with pearls.

3. Journal – Risk Factors for Intraocular Lens Dislocation After Phacoemulsification: A Nationwide Population-Based Cohort Study. Ga-In Lee, Dong Hui Lim, Sang Ah Chi, Seon Woo Kim, Dong Wook Shin, Tae-Young Chung. AJO. p86–96. Good article. Table 3 & the conclusion is all you need.

4. Book Chapter – Mark Twain – The Adventures of Tom Sawyer. Chapters 24-35 via Apple podcast. See also Sparknotes (narration) and Gutenberg (book text).

Finished The Adventures of Tom Sawyer! The LoyalBooks Apple podcast is excellent and free. A fun story. Will take a Mark Twain break before re-visiting with Huck Finn.
