Predictika · Prescription contact lens orders: toric daily disposables

An AI sales agent's toric contact lens order, checked before it goes out

An AI sales agent prepares an order for daily disposable toric contact lenses for a patient's two eyes: sphere, cylinder and axis for each eye, the pack size, the number of boxes and the total lens count. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published parameter table and returns a verdict, every reason and the figures it computed.

Scope: DAILIES TOTAL1 for Astigmatism orders for one or both eyes: base curve, diameter, sphere, cylinder and axis availability, pack sizes and the lens count. See everything this validator covers

This validator models orders for one lens line, DAILIES TOTAL1 for Astigmatism, using the parameter table Alcon publishes for eye care professionals, not just the scenarios shown below.

  • Base curve and diameter — the line is listed in a single base curve (8.6 mm) and a single diameter (14.5 mm), so any other value is rejected.
  • Sphere and cylinder — spheres from +0.50 to +4.00 D and from plano to −6.00 D in 0.25 D steps, and from −6.50 to −8.00 D in 0.50 D steps; cylinders of −0.75, −1.25, −1.75 and −2.25 D.
  • Axis — the axes offered depend on the sphere range and the cylinder: every 10 degrees for plano to −6.00 D with the three lower cylinders, 10, 20, 70, 80, 90, 100, 110, 160, 170 and 180 degrees in most other combinations, and only 10, 20, 160, 170 and 180 degrees for −2.25 D with positive spheres or spheres beyond −6.00 D.
  • Packs and lens count — packs of 5 (trial), 30 or 90 lenses, per eye; the total lens count stated on the order is compared with the boxes and packs ordered.

Any order for this lens line that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none are published, so this validator produces no price build-up or line-item quote), other contact lens lines, Alcon's surgical and other products, whether a given power is in stock in a given pack, regional availability, and clinical suitability or prescription validity.

The AI sales agentBuilds the lens order from the conversation and says it is ready.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Axes that depend on both sphere range and cylinderOnly with workarounds
The axes offered change with the sphere range and with the cylinder, so the table becomes a grid of combinations that has to be loaded and kept in step by hand.		Sphere, cylinder and axis are in one request; the axis is checked against the offered set for that exact combination on every call.
Sphere steps that change partwayOnly with care
Steps of 0.25 D up to −6.00 D and 0.50 D beyond need separate range and step rules, and a value between steps is easy to let through.		The offered sphere powers are one rule, so a value between steps is caught wherever it falls.
The same checks for two eyes in one orderOnly with care
Each eye needs its own copy of the power, axis and pack rules, and a one-eye order needs them switched off for the other eye.		Both eyes are checked in one call, and an eye with no boxes is simply left out.
A stated lens count that disagrees with the boxesOnly with workarounds
The count the agent states is a free-entry figure, so it takes an extra rule that multiplies boxes by pack size for each eye and compares the total.		The stated count is part of the request and is compared with the computed total on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for daily disposable toric contact lenses for a patient's two eyes: sphere, cylinder and axis for each eye, the pack size, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published parameter table and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote DAILIES TOTAL1 for Astigmatism lenses, base curve 8.6 mm and diameter 14.5 mm. Right eye: sphere -6.25 D, cylinder -1.25 D, axis 90, 2 boxes of 90. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The right eye sphere power of -6.25 D is not offered; available are +0.50 to +4.00 D and plano to -6.00 D in 0.25 D steps, and -6.50 to -8.00 D in 0.50 D steps. The left eye axis of 45 degrees is not offered for a sphere of -7.00 D with a cylinder of -1.25 D; axes are 10, 20, 70, 80, 90, 100, 110, 160, 170 and 180 degrees, except that plano to -6.00 D with -0.75, -1.25 or -1.75 D cylinders is offered in every 10 degrees, and -2.25 D cylinders with other spheres only at 10, 20, 160, 170 and 180 degrees.
    6. 
      
  6. The validator returned two blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for axes that depend on both sphere range and cylinder, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the right eye: sphere to -6.50 and the left eye: axis to 40 degrees.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The left eye axis of 40 degrees is not offered for a sphere of -7.00 D with a cylinder of -1.25 D; axes are 10, 20, 70, 80, 90, 100, 110, 160, 170 and 180 degrees, except that plano to -6.00 D with -0.75, -1.25 or -1.75 D cylinders is offered in every 10 degrees, and -2.25 D cylinders with other spheres only at 10, 20, 160, 170 and 180 degrees.
    12. 
      
  12. One finding cleared; still blocked on axis is not offered for this power (left eye).
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the left eye: axis to 100 degrees.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Two problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    19.
