Protecting Sight #104: Why we must confront hard historical truths. Acute retinal necrosis, Yag PIs, and Memories of President Lincoln: O Captain! My Captain!

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 – Hasan Kwame Jeffries – Why we must confront hard historical truths. “To move forward in the United States, we must look back and confront the difficult history that has shaped widespread injustice. Revisiting a significant yet overlooked piece of the past, Hasan Kwame Jeffries emphasizes the need to weave historical context, no matter how painful, into our understanding of modern society — so we can disrupt the continuum of inequality massively affecting marginalized communities.” (

This is a Ted Talk that will shake you and inspire you. Professor Jeffries is a remarkable storyteller and confronts hard historical truths.

2. Cataract Surgery – Uday Devgan MD – Remove one nuclear half first. Dr. Devgan writes, “There are many ways to divide and emulsify the lens nucleus in cataract surgery. Some advanced surgeons will chop the nucleus into many smaller segments before removing a single one from the capsular bag. Others find it easier to remove one nuclear half first before going after the second hemi-nucleus. This is the technique that can be easier to learn because once the first half is removed there is much more working room within the capsular bag.”
