Protecting Sight #293: How does artificial intelligence learn? Toric IOL, posterior capsulorhexis, & orbital apex syndrome. Mental models & living in the future.

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, podcast, or significant work.

Here is today’s list:

1. Ted Talk – Briana Brownell: How does artificial intelligence learn? “Today, artificial intelligence helps doctors diagnose patients, pilots fly commercial aircraft, and city planners predict traffic. These AIs are often self-taught, working off a simple set of instructions to create a unique array of rules and strategies. So how exactly does a machine learn? Briana Brownell digs into the three basic ways machines investigate, negotiate, and communicate. [Directed by Champ Panupong Techawongthawon, narrated by Safia Elhillo, music by Ambrose Yu].” (

Excellent summary.

2. Cataract Surgery – Ike Ahmed MD – Toric 1-piece IOL in presence of large capsulorhexis run: Using posterior capsulorhexis to stabilize. Well done, Ike.

3. Andrew Lee MD – Orbital Apex Syndrome.

Dr. Lee’s 450+ neuro-ophthalmology reviews are around 5 minutes each. Perfect for the busy clinician & trainee. I plan to watch one a day, from oldest to newest.

4. Episode 77: Living in the Future with Mike Maples, Jr. — “Mike Maples, partner at the VC firm Floodgate, shares how mental models shape his decision-making process, where to find the next big idea, and how to rally people to your cause.”

This is the second time I’ve listened to this episode. Filled with insights.
