Varilux Fitting Guide

FRAME SELECTION

1. Ensure minimum depth below pupil of 14mm for Varilux Ipseo New Edition, Physio 2.0 f-360°, Physio 2.0 Short; Comfort New Edition Short and Ultra Short, 17mm for Varilux Comfort New Edition and Ultra and 18mm for Varilux Liberty.

2. Adjust frame before taking measurements.

3. Set vertex distance at 12 - 14mm and pantoscopic tilt at 8° -12°

FITTING MEASUREMENTS

1. Take monocular PDs (use Digital Pupilometer for accuracy) or Visioffice.

2. Take monocular fitting heights while the patient is looking straight ahead. Fitting height should be lower than the centre of the pupil. Allow for frame slippage and avoid parallax by viewing the patient on the same eye level.

3. Check the lens will cut out with the centring chart. Select another frame if necessary.

VERIFICATION

1. Locate laser-engraved circles and add to confirm the lens is the correct type.

2. Confirm monocular PDs and fitting heights are within 0.5mm.

3. Check distance prescriptions.

4. Check add power. This is shown bellow the temporal engraved circle or it can be read as the difference between the front vertex distance and near powers.

5. Check prism power at prism reference point. Standard thinning prism is 2/3 add base down.
