The EZ-200 Advance serves optical practices, optometry clinics, dispensing counters, eye departments, and optical workshops. Optometrists, dispensing opticians, ophthalmic technicians and optical assistants use it to read the glasses patients arrive wearing, to compare new pairs with the prescription before collection and to take PD for dispensing.
Its single-button routine suits screening. The patient's glasses go into the instrument as they are; one press starts the measurement, and positioning and alignment happen automatically while the Hartmann-Shack sensor reads both lenses together. Because results repeat from one operator to the next, an assistant's reading at pre-test stands when the optometrist reviews it. A practice can place screening wherever its patient flow needs it: at pre-test, at reception or beside the dispensing desk.
Progressive and bifocal wearers are covered within the same routine, so a day of mixed single vision, bifocal and progressive pairs runs on one sequence of steps. The screen adjusts to each detected lens type, and for progressives the far-point and near-point distances from the optical centre appear alongside a progressive map. That map gives the dispenser a clear picture of the lens to share with the patient when explaining how it works.
Monocular and total PD support frame fitting from the same instrument. Each result can be printed on the built-in printer for the patient record, and the RS-232 interface carries readings to other Topcon products or a PC. Dust detection keeps the routine clean as well: when dust settles on the glass plates, the map shows where, so the plates are wiped at that spot before the next pair goes in.
