A contrarian view of employee turnover
Is it practical for medical practices to retain only stellar employees and pay them well above other practices, while letting one-fourth to one-fifth of their workforce go every year, to be replaced by new workers who will hopefully prove to be stellar? Would it be consistent with the culture of medical practices to reproduce the Netflix system of “high performance”?
All the more reason to smile
Matthew Hertenstein is a psychologist at DePauw University, Greencastle, IN, who has studied the photographs of children and high school students and then determined what happened to them later in their lives. It turns out that people who smile more warmly in their photos when they are young will allegedly live longer and happier lives.

Living in a bacterial world
In my own personal experience, there have always been infections that are difficult to treat (e.g., acanthamoeba or fungal keratitis), but that was no less the case 20 years ago than it is today. Bacterial infections are not (in my humble opinion) particularly more a concern today than they were a decade or two ago.
In the fast lane
Critical flicker-fusion frequency (CFF), as every ophthalmologist knows, is the lowest frequency at which a flickering light source is perceived to be constant (not flickering). Humans average a CFF of 60 Hz, but other animals measure with very different capabilities.
Match made in medicine
In Germany, ophthalmology struggles to attract strong applicants
A cutting-edge focus
Understanding these challenges, Ophthalmology Times is retooling its editorial direction, transitioning from a clinical newsmagazine to a resource that will explore the innovative concepts, insights, and discoveries in ophthalmology.
Defining the truth
Sometimes, it is hard to prove what you know to be true is actually true. So, it’s nice to know there is a paper confirming something I have also known to be true: People who lose visual acuity as a result of cataracts will—if they have cataract surgery to restore their vision—live longer than those who do not have surgery.
Technology may be important, but employees are the real key
What can we ophthalmologists in the wealthiest country in the Western Hemisphere learn from the success stories of ophthalmic institutions in other countries with different cultures, histories, and degrees of wealth? A great deal, notes Peter J. McDonnell, MD.
