Turn Handwritten Prescriptions into Structured Orders with AI

Handwritten prescriptions are the hardest input in optics: cramped boxes, personal shorthand, plus/minus signs that look alike, and notation (SPH, CYL, AXIS, ADD) that a general OCR engine has no understanding of. Plain text recognition gets you characters; it doesn't get you a correct order.

Why generic OCR isn't enough

Optical data has structure and rules. An axis is 0–180. A cylinder has a sign. An add is positive. A model that understands the domain can use those rules to disambiguate messy handwriting — and, just as importantly, to know when it isn't sure.

Confidence is the safety mechanism

The right approach pairs extraction with a confidence score per field. Clean, legible values pass automatically; anything uncertain is flagged for a human to confirm against the original image. You get the speed of automation on the easy 90% and a safety net on the hard 10%.

What you get out

  • Each field mapped into your schema, not just raw text.
  • A per-field confidence score so you know what to trust.
  • Low-confidence fields flagged for review before anything is saved.
  • Clean, exportable structured data ready for your lab system.
