BUR #56877 has been approved by @nonamethanks.

create alias lid_speculum -> eyelid_speculum
create alias eyes_forced_open_(device) -> eyelid_speculum

there is probably zero people on danbooru that know the name of this thing

The bulk update request #56877 (forum #425778) has been approved by @nonamethanks.
