If your indexes are sorted, you could keep a separate counter for the number of items removed and subtract it from $i when splicing.

However, it's much easier and more efficient to create a new array instead of splicing the same array, since each splice needs to copy all the elements from $i to the end of the array rearrange/copy the pointers to the elements from element $i to the end of the array. 

my @newarray;
foreach my $i (@arrayindex) {
   push @newarray,$array[$i];
}

Depending on your algorithm, you could probably do that at the same time/instead of building the @arrayindex array.

Another way would be to use grep (if you can determine which elements to keep based solely on their value): 

my @kept = grep { $_ < 4 and $_ > 10 } @array;

or even 
@array = grep { $_ < 4 and $_ > 10 } @array;
