Protecting Sight #106: The Genesis of Google. Cortex aspiration, retinoblastoma, the pursuit of presence, enneagrams, and Leaves of Grass.

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 – Sergey Brin + Larry Page: The genesis of Google. “Google co-founders Larry Page and Sergey Brin offer a peek inside the Google machine, sharing tidbits about international search patterns, the philanthropic Google Foundation, and the company’s dedication to innovation and employee happiness.” (

This 2004 Ted Talk is remarkable and prescient. I love watching Brin and Page display an entrepreneurial spirit and curiosity. I also recommend John Doerr’s Measure What Matters, in which he writes about the process by which Google and other companies evaluate the success of innovative ideas (OKRs, objectives and key results).

2. Cataract Surgery – Uday Devgan MD – cannula for cortex aspiration. Dr. Devgan writes, “Bimanual irrigation/aspiration for cortex removal has an advantage: it is easy to switch hands and then access a full 360 degrees of the capsular bag. It does require a third incision, and perhaps for that reason, coaxial irrigation/aspiration is more commonly performed in the USA. We have shown examples of new instruments like the transformable I/A handpiece which allow easier access to the sub-incisional area. But what if you don’t have this extra instrumentation?” Great pearl.

3. Journal – Everett LA, Rahman SA, Afshar AR. A Pediatric Patient With an Asymptomatic, Unilateral Retinal Mass. JAMA Ophthalmol. Published online September 24, 2020. doi:10.1001/jamaophthalmol.2020.2040

A 4-year-old girl presents with an asymptomatic, unilateral retinal mass with no visible calcification or subretinal fluid in the right eye and no further remarkable history. What would you do next?

4. Book Chapter – Walt Whitman – Leaves of GrassSparknotesWikipedia, and Gutenberg. Book 24 (Part I).

5. The Knowledge Project with Shane Parrish. Episode 91Russ Hudson: The Pursuit of Presence — “Author and co-founder of the Enneagram Institute, Russ Hudson, explains how the Enneagram was developed, how it helps us grow personally and with others, the nine interconnected personality types and what it means to be present.”

Shane Parrish continues to showcase thought leaders and cutting edge concepts.
