Combigan
"I was on Betoptic for years and my pressure was still a bit higher than we wanted it to be. After some trial & error, we've discovered that if I put the Combigan in one eye and the Betoptic in the other, my pressure is better than it's ever been. Around 14 which is unheard of me. It's working great and the only side effect I have is a bit of redness at times."
