How to close a file if successfully opened

I have an app that reads config info from a .ini file.
But the first time the app is run there is no .ini file exits.

Below is the code I'm using to ensure that the .ini file is closed if
opened; but surely there's a better way?

I really want to get rid of the first if command

if {![file isfile $::config::filename]} {
    return
}
try {
    set fh [::ini::open $::config::filename -encoding utf-8 r]
    set ::config::geometry \
        [::ini::value $fh Window geometry [wm geometry .]]
    tk scaling [::ini::value $fh Window scale [tk scaling]]
    ttk::style theme use \
        [::ini::value $fh Window theme [ttk::style theme use]]
    set ::config::tab [::ini::value $fh Window tab]
} finally {
    if {[info exists fh] && $fh ne ""} {
        ::ini::close $fh
    }
}
