Meaning:
The Doctor is a genius known for saving planets, species, etc., and even though he often makes plans up on the spot he is always in control. When The Doctor lost his sight he had to rely on Nardole, an almost moronic companion, because he was the only one that knew about his condition. He was also subject to being stuck in situations where sight was a necessity like for reading a book and inputting a rotating number lock. 
His lack of sight highlighted his hesitation to trust others putting him in situations that made him uncomfortable. However, it also emphasized exactly how remarkable his other skills are because of the numerous times he saved the world following going blind.
