I took the survey. I see the value in this. Simply because aesthetics are important (big concern for patient) and maybe you could use data to help them make a big decision in a data driven way on which type of surgery to choose.

As with other surveys like this, and perhaps eye exams, I found myself several times thinking "these two look the same", or "I have no obvious preference", or "I like both". I'm bringing it up because I think that's valuable data that should be considered.
