The Synchrony lens is a complicated, but ingenious piece of equipment- a double lens implant connected by adjustable “pistons”, where one lens is a high minus and the other is the plus lens. The plus lens moves back and forth to generate accomodation. The ability of engineers to design such a lens that can fit into a shooter is really something. But I recently read in one of the throwaways that after two years, the best the patients could muster is one diopter of accomodation. And that’s the average- that means plenty are doing less (and plenty doing some more). It’s frustrating that such a marvel of engineering still can’t deliver the “holy grail” of at least three diopters.
