So strange, I asked myself the exact same question today.
I was planning to go to Dr Taban for orbital rim implants and whatever soft tissue changes I need but after reading Lazlo say he is going for the lefort 3, part of me feels like I might be missing out if I don't try this.
I have seen a full lefort 3 on one of Sailer's patients but it didn't improve the eyes, the patient still needed canthoplasty and maybe other things. I saw the patient in person, not in photographs.
Hmm actually it could have something to do with the SHAPE of the orbital rims, not just how far back they are, if the rims start too low down then if you advance them the eyes still won't look right.
