M3 Automatic Refractor / Automatic Keratometer / Non-contact Tonometer from Marco

M3 Automatic Refractor / Automatic Keratometer / Non-contact Tonometer from Marco


Marco proudly introduces the newly redesigned M3. The new M3 offers the same space and time saving features as well as the dependability of the original M3, because it is 3 instruments in one, the only one of its kind.

The newly designed M3 presents several enhanced features such as a smaller footprint, to save even more space, and a new exterior design, but most importantly, the M3 now uses SLD (Super Luminescent Diode) and a highly sensitive CCD device to provide Zonal Ring-Image Technology. This makes it possible to now accurately measure patient with cataracts, corneal opacities, IOLs, and post LASIK.

The M3 remains totally automatic when aligning, tracking, and focusing on the patients' eye and possesses the same automatic fogging system that minimizes accommodation throughout the exam. The tiltable screen, motorized chinrest and easy load paper make the M3 user friendly as well.
