Protecting Sight #290: How quantum physics can make encryption stronger. Decentered IOL, 3-D capsulorhexis modeling, & the trochlear nerve. The lead and the ending.

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 – Vikram Sharma: How quantum physics can make encryption stronger. “As quantum computing matures, it’s going to bring unimaginable increases in computational power along with it — and the systems we use to protect our data (and our democratic processes) will become even more vulnerable. But there’s still time to plan against the impending data apocalypse, says encryption expert Vikram Sharma. Learn more about how he’s fighting quantum with quantum: designing security devices and programs that use the power of quantum physics to defend against the most sophisticated attacks.” (

Excellent talk.

2A. Cataract Surgery – Uday Devgan MD – 1058: Quiz: Why did the IOL decenter? Nice save.

2B. Lane Ulrich MD – Capsulorhexis Initiation Critiques – 3-D imaging. “A video critique of a slowly initiated capsulorhexis with 3D modeling to display why it is not more effective.”

Nice 3-D video and narration!

3. Andrew Lee MD – Trochlear Nerve (CN IV or 4th nerve)

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. William Zinsser, On Writing Well: The Classic Guide to Writing Nonfiction. Chapters 9 (The Lead and The Ending).
