Die DOC – 38. Internationaler Kongress der Deutschen Ophthalmochirurgie - ist die zentrale Fachveranstaltung für Augenchirurgie in Europa und findet 2026 von 18.-20. Juni in Nürnberg, Deutschland statt. Jährlich treffen sich Fachleute aus Medizin, Wissenschaft und Industrie, um sich über aktuelle Entwicklungen, neue Technologien und bewährte Behandlungsmethoden auszutauschen. Im Fokus steht ein kompaktes wissenschaftliches Programm mit Vorträgen, Symposien, Masterclass-Formaten, Consilien, praxisnahen Wet- und Drylabs und Workshops. Diese verbinden theoretisches Wissen mit praktischer Anwendung und fördern den fachlichen Austausch. Programmatisch werden alle wichtigen Disziplinen der Augenheilkunde und Ophthalmochirurgie abgedeckt: • Kataraktchirurgie • Glaukombehandlung • Refraktive Chirurgie • Netzhautchirurgie • Hornhautchirurgie • Lid- und Orbitachirurgie • Strabologie Das medizinische Programm wird ergänzt durch ein umfassendes Vortragsangebot für ophthalmologisches Assistenz- und Managementpersonal sowie spezielle Seminare für niedergelassene, klinisch und belegärztlich tätige Kollegen. Ein besonders auf Ärzte in Weiterbildung zugeschnittenes Programm rundet die Fortbildungsveranstaltung in Nürnberg ab. Ergänzt wird der Kongress durch eine Industrieausstellung, in der Unternehmen aus Medizintechnik, Pharmazie und branchennaher Dienstleistung modernste und innovativste Produkte und Lösungen präsentieren. Die DOC in Nürnberg dient damit als wichtige Plattform für Weiterbildung, Networking und den Transfer neuer Erkenntnisse in die augenärztliche und ophthalmochirurgische Praxis und setzt Goldstandards.

Toric Trouble works up the outcome after a toric intraocular lens. The app calculates backwards: from biometry, implanted lens and subjective refraction it determines which of the three does not fit the other two. FOUR POSITIONS • Lens — which lens is actually at work? The main clinical question. • Refraction — what refraction was to be expected? Turning the axis simulates a misaligned lens. • Cornea — which cornea fits lens and refraction? Comparing it with the keratometry is the diagnosis. • Plausibility — all three checked against each other, naming the ghost astigmatism: what none of the three explains. FURTHER FEATURES • A recommendation where to rotate, what residual cylinder would remain at best — and whether an exchange is the better choice • Axis diagrams with uncertainty wedges from the actual measurement tolerances: cornea 0.30 D vectorial, refraction 0.25 D, read-off axis ±3° • Keratometric index selectable in four steps: 1.3375 (Javal), 1.332 (Zeiss), 1.3295 (Kooijman), 1.3281 (Liou & Brennan) • Effective lens position from the postoperatively measured anterior chamber depth instead of a prediction — this removes the largest uncertainty from the calculation • Surgically induced astigmatism (SIA) from pre- and postoperative keratometry • Plausibility check on every entry: impossible values block the calculation rather than yielding a result that looks like any other • Complete manual inside the app, in three languages CALCULATION CORE The basis is the Castrop formula, developed with Prof. Achim Langenbucher, Saarland University, and published peer-reviewed: Langenbucher A et al. Considerations on the Castrop formula for calculation of intraocular lens power. PLoS One 2021;16(6):e0252102 Langenbucher A et al. The Castrop formula for calculation of toric intraocular lenses. Graefes Arch Clin Exp Ophthalmol 2021;259(11):3321–3331 Both papers are linked inside the app, directly below the result. Where the app goes beyond what is published, it says so and describes the calculation path in full in the bundled manual. All calculation runs on the device, in C99 compiled into the binary. No account, no sign-in, no network, no advertising, no data collection. German, English and Italian. For ophthalmologists and other eye care professionals. Not a medical device; responsibility for every clinical decision remains with the user.
