Orianna counterplay

I just got out of a vs game. I was faring well enough in the early game and was able to get a big kill lead but due to 's poke I fell slightly behind in farm. I wasn't able to farm that well since every time I came back to lane I felt like I would have to fight immediately and be low enough health that I'd have to back to not give up a big shutdown to their jg or an ult snipe from their support. The only alternative I saw was to try to farm only to get 1/3 of my health taken down by each of qw then have to back and repeat the process over again. Anytime we fought I played it well, rarely missing e, only got hit by her ult once in the game, and I started c pots and built Banshees 2nd item to fare better against , but even when I was 5/1 and she was 1/5 the fights were too close for comfort. The game went well, I went 12/1 and farmed decently, but I feel it could have went much better and want to know what to fix to make that happen.
