Topcon, Marco and Keeler are 3 major manufacturers of Non Contact Tonometers. Additionally, many independent companies are importing NCT's and placing their own name on them.
One of the things you should check on prior to purchasing an NCT, is the philosophy of the manufacturer or importer. How do they service their instruments? Do they import parts or order them as needed? How long will they support an instrument when the next model comes out?
While we would like to obtain training on every NCT that is on the market, the reality is that some companies refuse to train outside vendors and others cannot. If you are having a problem with your NCT, contact us today and if it is something that we cannot handle ourselves, we will help you find someone who can solve your problem.
