The CSV-2000, CSV-1000 and ESV-3000 are important tools for the routine eye care of patients. The devices provide the combination features of ease of use, standardization and accuracy. Just plug in the devices and they are ready to go for evaluating the vision of your patients. The three major clinical uses involve early detection of eye disease and evaluation of treatment, such as in glaucoma, diabetic retinopathy and macular degeneration; documentation for cataract vision loss and the need for cataract surgery; and evaluation of visual performance, such as in sports vision, contact lenses, IOLs or refractive surgery.
