If it can be filled by the opponent, then it is not an eye.
If it can be filled by the player, then maybe because suicide is allowed.
"capture" is less suitable than "removal".
"surrounded" is less exact than "adjacent and only adjacent to".
"empty" is more common than "vacant".

Hence your attempt does not serve its purpose.

The safe way to define single point eye is to ignore the seki case and
do the following:
First define two-eye-formation

then [but why?] define [single point] eye as "one of the empty
intersections of a two-eye-formation".
For sekis, matters are much more complicated but solved.
