Protecting Sight #196: The puzzle of motivation. A perfect capsulorhexis circle, Parkinsons’ microvascular changes, & internuclear ophthalmoplegia. The Warren Buffett Way.

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’s today’s list:

1. Ted Talk – Dan Pink: The puzzle of motivation. “Career analyst Dan Pink examines the puzzle of motivation, starting with a fact that social scientists know but most managers don’t: Traditional rewards aren’t always as effective as we think. Listen for illuminating stories — and maybe, a way forward.” (

Not sure that Mr. Pink’s comment of graduating in the “bottom 10%” of his law school class was such a bad thing. And especially considering he attended Yale Law School!

An engaging Ted Talk worth watching.

2. Cataract Surgery – Uday Devgan MD – Tracing a Circle to make the Capsulorhexis. Dr. Devgan writes in part, “A very simple technique for new surgeons who are struggling with the capsulorhexis is to trace the intended path with the tips of the forceps. If the forceps tip traces a circle, then a perfect capsulorhexis will follow.” Excellent pearls!

3. Robbins CB, Thompson AC, Bhullar PK, et al. Characterization of Retinal Microvascular and Choroidal Structural Changes in Parkinson DiseaseJAMA Ophthalmol. Published online December 23, 2020. doi:10.1001/jamaophthalmol.2020.5730

4. Andrew Lee, MD – Internuclear Ophthalmoplegia (INO) (YouTube) – Love Dr. Lee’s whiteboard reviews.

5. Robert G. Hagstrom, Jr. The Warren Buffett Way (1994) – I picked this up from the local library book sale. An excellent overview of Warren Buffett’s investing philosophy. This edition in from 1994, and Amazon shows a 3rd edition (2013). Chapter 5.

Includes Superb vignettes which provide examples of Buffett’s analysis for making investments.
