The CGT-2000 is able to detect things more acurately than a standard visual acuity test. This model was created from a predecessor, the CGT-1000, which was received well by many medical facilities. The newer model addressed customers' feedback to ensure even an even higher rate of customer satisfaction. The CGT-2000 is effective before and after cataract surgery diagnosis and follow up observations. A special function of this machine is its binocular testing. Patients can be tested with both eyes open to accurately assess their real-world vision.
