Protecting Sight #49: Sleep is your superpower.

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 – Matt Walker: Sleep is your superpower. “Sleep is your life-support system and Mother Nature’s best effort yet at immortality, says sleep scientist Matt Walker. In this deep dive into the science of slumber, Walker shares the wonderfully good things that happen when you get sleep — and the alarmingly bad things that happen when you don’t, for both your brain and body. Learn more about sleep’s impact on your learning, memory, immune system and even your genetic code — as well as some helpful tips for getting some shut-eye.” (

In college and medical school, I could never study past 10 pm. The grind was real and I treasured my sleep. Walker gives an excellent talk and I hope to learn more about the superpower of sleep. 20 minutes and 11 million views.

2. Cataract Surgery – Ike Ahmed MD & Dr. Felipe Vejarano. Very few people can get ophthalmologists to wake up early & stay up late to learn the great pearls of cataract surgery. #IkeNeedsAHaircut is one of those people. Today’s webinar is available on YouTube.

A, Axial computed tomography (CT) of the orbits with contrast shows a large destructive lesion in the right sphenoid bone and anterior aspect of the middle cranial fossa. B, A T1-weighted magnetic resonance image (MRI) of the brain and orbits without contrast shows the involvement of the right temporal lobe. The lesion can be seen also involving the right side of the sphenoid bone, orbital apex, and scalp anteriorly. The scale across the bottom of each image is measured in centimeters. A indicates anterior; R, right.

Aesop's Fables by Aesop

4. Book Chapter – Aesop’s Fables via Apple podcast.

Warren Buffett often mentions Aesop’s Fables during the Berkshire Hathaway annual meetings. This podcast includes 25 fables and is filled with life lessons. Worth listening to again and again.

5. Regional Eye Associates August newsletter: Seven Common Myths about Children’s Eye Health. Includes in-person & virtual back-to-school tips!

I recently hand-delivered 100 N-95 masks to ophthalmology colleagues and staff on the frontlines at the Wills Eye Hospital.  The gift was arranged through a generous donation by LanceSoft and my brother, Al. With thanks for helping colleagues on the front lines!
