This is a very nice system which works flawlessly. It has recently had an upgrade to the memory and also has a brand new hard drive. It is currently being used every day in my office but is going to be replaced by an OCT within a week. The scan takes only a few minutes and gives a very nice image of the optic nerve with parameters and comparison to normative database. The unit is running the latest software. It comes with its own power table. This is a wonderful, diagnostic device for an office that doesn't want to spend a fortune on an OCT. It reimburses the same amount as an OCT.
