Where to get a Tonometer?

Hello, My husband Blake was diagnosed with Glaucoma about a year ago and we are currently searching for an affordable IOP measurement device he can use at home. Can you tell me where we might get one? Also, do you have an advice on the best model? If there are any studies, such as that described in the forum, he would be happy to take part. Kindest regards, Natina
