Final Inspection Checklist
08-2008
When completed eyewear is received from the lab and before calling the patient, check that everything has been received correctly. Also be sure that the quality, alignment and cleanliness of the glasses are exactly what you expect to deliver. Follow the six steps listed here, comparing the patient record card or electronic file and the lab invoice.
- Complete the Visual Checks.
- Lens style, material and treatment
- Frame name, size, color
- Surface and edging, grooving, drilling quality
- Note the base curve and lens manufacturer used on
the record card or chart (important for later
troubleshooting)
- Measure and Confirm the Mechanical Requirements.
- Seg height (top of segment or Fitting Cross to
lowest edge of lens)
- Seg PD (near PD for RS, FT, FTT or Occupationals)
- Distance Monocular PD for inked progressives
- Center or edge thickness if specified single vision, Bifocal or Trifocals
- Confirm the Optical Components.
- Single Vision, Bifocal or Trifocal
- Measure the strongest lens first; it’s easiest to center. The
other lower powered lens is then less prism sensitive.
- Clamp the lens and center the target (OC) or prescribed
prism in the center of the reticle, adjust the stage to be
equally touching the bottom of both eyewires.
- Verify Rx as ordered and dot the lens.
- Unclamp the lens and measure the other lens; do not
change the stage position.
- Center the OC or prescribed prism horizontally, verify the
Rx, dot the center and note any vertical imbalance.
- Measure and record PD; are the OCs in the correct position
vertically?
- If multifocal, verify add as a front vertex measurement.
- Progressive or Near Variable Focus Lenses
- For the right lens, verify the distance power in the distance
checking circle. Adjust the stage to be equally touching the
bottom of both eyewires so the lens is oriented correctly.
- Verify the power of the left lens.
- Clamp the right lens with the manufacturer’s PRP ink dot
centered in the opening or stop of the Lensmeter. In Varilux
progressives, this is 4mm below the Fitting Cross. Adjust
the stage to be equally touching the bottom of both
eyewires. Note the amount prism. This is the OC or
point of prescribed prism. Prism thinning is considered
prescribed prism.
- Center the left lens PRP in the stop and record any vertical
imbalance. Remember the FC may be of different heights
so the imbalance is the difference between the values at
the PRP.
- Confirm add power using the engravings. The engravings
also confirm right and left lenses, material and manufacturer.
To confirm add on the lensmeter, verify add as a front vertex
measurement or use a automated lensmeter that has a
back vertex compensation factor built in.
- Record any Variation from the Order in the Patient Record or Chart for Later Reference.
- Alignment – If the visual, mechanical and optical checks are acceptable, complete bench alignment. Confirm that the frame
looks good, straight and symmetrical.
- Clean-up – Remove any ink marks, spray the lenses with a lens cleaner and towel dry. Remove any tags or labels not
needed. Select the right Luxottica collection case and you are ready to call the patient.
