As far as Kannan is concerned, nothing is as important as his daughter.

“As far as” vs “so far as”
“As far as” and “so far as” both mean the same thing. But “so far as” might be thought of as a less formal version and used less in spoken English. But “as far as I know” is more likely to be used in everyday conversation.
