Synthetic teaching case
Case 1: concordant low-risk LASIK screen
Synthetic example in which all four risk pathways and independent tissue-safety checks are complete.
Not real patient dataThis worked example was created to teach the current CER-AI v2.0 rules. It is not a clinical decision.
Source inputs
| Field | Value |
|---|---|
| Procedure | LASIK |
| Age / thinnest | 30 years / 540 µm |
| I-S / SRAX | -0.20 D / 10° |
| Manifest MRSE | -4.00 D |
| Flap / ablation / RSB / PTA | 110 / 60 / 370 µm / 31.5% |
| Final BAD-D | 1.20 |
Pathway evaluation
| System | Calculation / finding | Result |
|---|---|---|
| ERSS | 0 | PASS |
| BAD-D | 1.20 normal | PASS |
| NICE | 4 | PASS |
| PS3 | No Moderate/High factors | PASS |
| Tissue safety | RSB 370 µm; PTA 31.5% | PASS |
Final CER-AI result
PASS
Report summary
The report shows each pathway separately, preserves the source measurements, and states that PASS is decision support—not a guarantee of zero ectasia risk or autonomous surgical clearance.
Learning points
- Concordance strengthens interpretability but does not prove future stability.
- A negative signed I-S represents superior rather than inferior asymmetry; SRAX does not create an inferior-risk factor.
- All source identity, quality, eligibility, and surgeon-review requirements still apply.
