Protecting Sight #207: Atomic clocks, satellites, & a smartphone’s location. Zonular dehiscence and endophthalmitis microbiologic cultures. John Adams as a 15 year old Harvard student.

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 – Wilton L. Virgo: How does your smartphone know your location? “GPS location apps on a smartphone can be very handy when mapping a travel route or finding nearby events. But how does your smartphone know where you are? Wilton L. Virgo explains how the answer lies 12,000 miles over your head, in an orbiting satellite that keeps time to the beat of an atomic clock powered by quantum mechanics. [Directed by Nick Hilditch, narrated by Addison Anderson].” (ted.com)

2. Cataract Surgery – Uday Devgan MD – Cataract Quiz: Zonular Dehiscence. Dr. Devgan writes in part, “Our guest surgeon is Dr Willie Kan from Malaysia and he presents a very tough case: a traumatic white cataract with an area of zonular dehiscence. He expertly manages this situation and provides some great teaching points in dealing with these tough cases.”

Excellent management of a complicated case.

3. Patel, Samir N. et al. Endophthalmitis after Cataract Surgery: Changes in Management Based on Microbiologic Cultures. Ophthalmology Retina, Volume 5, Issue 1, 16 – 22.

Excellent article from the Wills Eye Retina Service.

4. David McCullough, John Adams (2001). Chapter 1, Part II, page 29-42. Nice description of Adams time as a 15-year old Harvard student.
