PREVENT WHAT YOU CAN. UNDERSTAND WHAT YOU COULDN’T.

Many complications leave their traces before the laser fires — in the geometry, the history or the device settings. RLES AI hunts their preconditions at the planning stage, and when an adverse event does occur, investigates it with the discipline of an incident analysis, not the reflex of blame.

PREVENTION: THE PRECONDITION HUNT

• Hinge ramp calculation — the ΔK between the steep axis and the hinge site converted to microns; hinges thinner than the safety floor are flagged before a free flap can happen^[1]
• Buttonhole geometry, keratome kinematics (linear vs rotational cutting heads behave differently)^[2], and the topical-anaesthetic rule that prevents epithelial slides mimicking buttonholes^[3]
• Narrow-angle screening on every preop topography, medication anamnesis (isotretinoin, amiodarone, topiramate) and chronic-disease query on every case

ANALYSIS: A CONFIDENTIAL IN-CLINIC INSTRUMENT

When something goes wrong, the complication module runs a structured investigation: an atlas of 45+ entities across six families, mimic tables (what looks like a buttonhole but is not), a four-grade severity score, and root-cause categories that explicitly include device condition, calibration history, blade lots and theatre environment. The report is an internal-use document built on just-culture principles — process analysis, not person analysis — and closes with preventive actions, including revised nomogram values for a future second procedure where appropriate.

THE QUESTIONS COME BEFORE THE VERDICT

The module generates a neutral, complication-specific question set — which keratome, which settings, when was the last calibration, what did the interface look like — and the report is not written until the questions and imaging are complete. Understanding first; conclusions after.
