What can be done about complex lateral canthus rounding? (photos)

I have scar webbing from a previous lower bleph. My case seems quite complex compared to other cases of rounding I have seen: there appears to be a split between the lower eyelid and the webbing as opposed to the whole angle being blunted. Is this resolvable? I am also very wary of risk. Is there a high chance the webbing gets worse or say my lower eyelid droops post surgery?
