Protecting Sight #40: How AI could extend the mind. A submarine phaco chop in search of Moby Dick. #NoRubberBullets #NotOneMoreEye #TearGasEyeSafety

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 – Arnav Kapur – How AI could become an extension of your mind (May 2019) “Try talking to yourself without opening your mouth, by simply saying words internally. What if you could search the internet like that — and get an answer back? In the first live public demo of his new technology, TED Fellow Arnav Kapur introduces AlterEgo: a wearable AI device with the potential to let you silently talk to and get information from a computer system, like a voice inside your head. Learn more about how the device works and the far-reaching implications of this new kind of human-computer interaction.” (

TED Fellow Arnav Kapur invents wearable AI devices that augment human cognition and give voice to those who have lost their ability to speak. A remarkable talk (9 minutes) which introduces technology to help millions worldwide.

2A. Cataract Surgery – Uday Devgan MD – Submarine chop (Dr. Pradip Mohanta). Dr. Devgan writes, “For a dense cataract, performing phaco chop is challenging because the central lens nucleus is so hard that the chop does not always propagate all the way through. Our guest surgeon, Dr Pradip Mohanta from West Bengal, India has a great technique to facilitate phaco chop in these brunescent cataracts: the submarine chop.”

2B. Dr. Neto Rosatelli – Spiral Rhexis and Mohanta’s Submarine Chop. This video clip appeared in the YouTube screen after I watched Dr. Devgan’s clip. Excellent.

3. Journal article – Deluged by Data – “Keeping up with and implementing the latest evidence poses myriad challenges for clinicians. This month’s feature takes a look at how physicians, trial investigators, and organizations can speed the adoption of evidence-based medicine to ensure that patients receive the best current care.” (EyeNet December 2019).

This is a good article. I especially enjoyed the “Five Recent Studies Worth Attention” on page 47. Have already featured the glaucoma pick on SLT vs. drops in the LiGHT Study.

4. Book Chapter – Herman Melville – Moby Dick. Listened to Chapters 124-127 via See also Sparknotes (narration) and Gutenberg (book text).

Can it be that in some spiritual sense the coffin is, after all, but an immortality-preserver! I’ll think of that. But no. So far gone am I in the dark side of earth, that its other side, the theoretic bright one, seems but uncertain twilight to me.

Ahab (speaking to himself), Chapter 127

5. #NoRubberBullets & #NotOneMoreEye Campaign – I reposted my blog on eye safety with rubber bullets & tear gas. The blog post is here. A shout-out also to Esther Choo, MD MPH @choo_ek who posted the tweet above. Her tweets often go viral and have greatly helped the mission of protecting sight. #TearGasEyeSafety

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