Medical disclaimer

DIOPTRA is a learning tool, not a medical device

DIOPTRA is a study platform for the postgraduate ophthalmology examinations of the International Council of Ophthalmology (ICO): Visual Sciences, Optics · Refraction · Instruments, Clinical Ophthalmology and Advanced. The content provided is for educational purposes only.

What DIOPTRA is NOT

• Not a medical device under MDR (EU) 2017/745 or MepV (CH).
• Not Software as a Medical Device (SaMD).
• Not a diagnostic tool.
• Not a clinical decision support system (CDSS).
• Not a guideline source for patient care.

What DIOPTRA is

• A structured study aid built around curated cards.
• A self-assessment tool for gauging knowledge before an examination.
• A collection of content aligned with the official ICO Residency Curriculum.

Important limitations

1. Content may be incorrect, outdated, or incomplete. Every card carries a verified reference (textbook, guideline, or peer-reviewed publication). Users are expected to consult the source themselves for any clinical application.
2. Medicine evolves.Guidelines, classifications, and therapeutic recommendations change. Content on DIOPTRA reflects the state of the field at the card’s publication date, not necessarily current clinical practice.
3. No patient application without independent verification. Users must not rely on card content as the basis for diagnosis, therapy, or patient communication without independent verification. Every clinical decision must rest on current guidelines, consensus documents, and your own professional responsibility.
4. No warranty regarding examination outcomes. The provider does not warrant that using DIOPTRA will result in passing an ICO examination. Examination success depends on many individual factors.
5. Automatic answer evaluation is not an expert judgement. The Deep Review feature compares your typed answer to a stored reference solution using a language model (Anthropic Claude Haiku). The resulting score is a heuristic estimate, not an examination grade and not a medical judgement.

If you find a factual error in a card, please report it to amr@dioptra.amrsaad.de with the card reference and source. We review and correct within seven days and publish a public release note.
