POTEC PRK-8000 Auto Ref-Keratometer | Refraction & Keratometry

Description

Y-axis Auto Pupil Tracking: The pupil position detecting automatic height adjustment system reduces
measurement time. By only clicking a button, user can switch the mode
from auto to manual tracking.

Near Vision Simulation: Determine the necessity of progressive lenses with the "Near Vision Simulation." Once a refractive
measurement is completed, further diopter power between +0.00D and +3.50D can be applied in
0.25D or 0.50D increments to ensure a comprehensive examination of presbyopia.

Retro - illum Mode: Opacity (cataract) in the crystal or fault of the contact lens are visible on the monitor by the method of
projecting light on the pupil.

Extensive Dioptric Measurement Range: PRK-8000 provides an extensive dioptric measurement range (-30D ~ +25D),
and the radius of curvature for keratometry range (5.0mm ~13.0mm) help to
measure almost all human eye.

Electronic Joystick: Power of electronic joystick provides soft & smooth operation
experience.

Tilting & Swivel LCD: (User-oriented tilting LCD Screen) 7 inch (800x480) LCD display.
· Tilt : 180°, Swivel : 135 ~ 145° · Automatic screen vertical inversion.
