Introduction

The Canon Full Auto-Refractor Keratometer is very easy to operate using the auto-feature. Once the eye is located on the alignment screen, just press start!

The unit's motorized optical head automatically aligns, acquires the readings and then automatically moves over to the opposite eye to perform the same function. The unit can also be operated manually to acquire readings.

Measurement functions include:

• Auto-refraction only and combination refraction and keratometry
• Corneal peripheral keratometry at 30-degree angle from eye center
• Pupil diameter measurement
• IR retro-illumination to observe lens opacity (cataracts) and scratches on contact lenses.
• Corneal diameter and base curve of contact lens

Features

Auto Ref-Keratometer RK-F1

• Easy, comfortable operation
  The RK-F1 replaces the conventional joystick with a trackball and roller. Once the examinee's pupil is visible in the monitor, you just press the start button to begin - and complete - measurements of refraction and keratometry.

• Wide measurement range
  For refraction, dioptric measurement range of -30D to +22D allows examination of strong myopia and other abnormalities. For keratometry, the radius of curvature extends from 5.5mm to 10.0mm.

• Corneal periphery measurement
  The RK-F1 can be used to make a series of measurements at a 30 degree angle from the eye's center along the attentive meridians.

• Retro-illumination
  Through retro-illumination, the RK-F1 brings you a detailed view of the eye's that's particularly useful for identifying cataracts, vitreous opacity, scars, and other serious eye problems.

• Motorized chin rest
  A motorized chin rest offers easy adjustment of the unit when beginning the eye examination.

• Ergonomic centralized control keys
  The layout of the operation panel makes the unit easy to use from either a seated or standing position. Control keys for each of the unit's main functions are grouped together for your convenience.
