Protecting Sight #205: The benefits of a good night’s sleep. Optimizing cataract surgery efficiency while reducing infections & waste. Hearing loss, vertigo, & retinal vascular changes in a young female.

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 – Shai Marcu: The benefits of a good night’s sleep. “It’s 4am, and the big test is in 8 hours. You’ve been studying for days, but you still don’t feel ready. Should you drink another cup of coffee and spend the next few hours cramming? Or should you go to sleep? Shai Marcu defends the latter option, showing how sleep restructures your brain in a way that’s crucial for how our memory works.” (

Ted has many excellent talks on the importance of sleep. Wish I had watched these talks in high school and onwards.

2. Cataract Surgery – Uday Devgan MD – Never make an incision like this! Dr. Devgan writes in part, “If you are in your surgical training or if you are a new surgeon with less than 1,000 cataracts under your belt, you really MUST watch and learn from this video. A good surgeon will learn from his/her mistakes. A truly wise surgeon will learn from the mistakes of others. That’s you.”

Excellent pearls.

3. Chang, DF. Needless Waste and the Sustainability of Cataract Surgery. Ophthalmology, Volume 127, Issue 12, 1600 – 1602.

Dr. Chang writes and excellent editorial on an increasingly important topic … medical waste. He shares the success of the Aravind Eye Hospital System and their lower endophthalmitis rate vs. the US. I performed cataract surgery training at Aravind as a resident and marveled at their LEAN management principles and efficiency. The current pandemic will also yield best practices and teaching points in the months and years ahead.

4. Reddy AK. Retinal Vascular Changes in a Young WomanJAMA Ophthalmol. 2017;135(5):497–498. doi:10.1001/jamaophthalmol.2016.4816.

Nice case and review of this rare condition.
