I did a 1.67 for a patient who was about a -12.00 and the lab recommended the 1.67 because the 1.74 was only like 1.5 mm thinner at the edge. We don't deal with 1.74 very often probably because options are limited so I'm not as familiar with it. Any insights from someone that does alot of 1.74. Do patients seem to like it a lot over a 1.67?
