This app is designed for use by all medical, nursing and allied health clinicians in Emergency Departments across New South Wales. It provides a quick and simple guide to recognising important signs and symptoms, and management of common eye emergencies. The app will also be of assistance in triaging patients to appropriate care within the health system. The content within this app was developed by ophthalmic and emergency clinicians of the NSW Agency for Clinical Innovation (ACI). These guidelines have not undergone a formal process of evidence based clinical practice guideline development however they are the result of consensus opinion determined by the expert clinician working group. They are not a definitive statement on the correct procedures rather they constitute a general guide to be followed subject to the clinician’s judgment in each case. The consensus opinion provided is based on the best information available at the time of writing. To help with ease of use, this manual has a high graphic content, and is subdivided into anatomy, basic ophthalmic workup (history, examination, diagnostic techniques and treatment), and management of common eye presentations. Each of the presenting conditions is subdivided into the following sections: • Immediate action (if any) • History • Examination • Treatment • Follow-up - When to refer?

Opioid Conversion Calculator is built for health professionals who need a clear, efficient way to compare opioid doses and review the clinical context behind a conversion. Built by a pharmacist. CALCULATE AND COMPARE - Calculate total oral morphine equivalent (OME) across multiple opioids and routes: oral, parenteral, rectal, sublingual and transdermal. - See every converted dose at once, after applying a chosen Target OME percentage for incomplete cross-tolerance. - View conservative, rounded-down target and breakthrough dose suggestions. - See where a daily dose sits: the header warms from orange at 50 mg/day (CDC 2022) to red at 120 mg/day (Opioids Aware). Adjust the thresholds or turn the guide off. - Methadone uses its own dose-dependent model, and its results are clearly marked as not a starting dose. - Convert the same opioid between routes, such as oral and parenteral morphine, with the method and sources shown. EVERY RESULT, IN CONTEXT - Each result opens with the converted dose, then products, clinical information, breakthrough dosing and switching timing. - Read practice points alongside formulation-specific pharmacology, with links to the supporting sources. - Check when to start the new opioid when switching between patches, modified-release opioids and CSCI. Switching timing is also in the menu, free for everyone. - View official products and strengths for Australia, the United States, Germany, France and Spain, chosen independently from the app language. TAILOR THE WORKFLOW - Edit conversion factors and choose which opioids appear, with Pro. - Export and import settings when moving between devices, with Pro. - Works offline, including on first launch. - Use the app in English, French, German, Italian, Portuguese (Brazil) or Spanish. PRO ACCESS The calculator stays free: the combined OME and every converted dose need no account or purchase. Pro adds breakthrough dosing, switching timing, products and clinical information to every result, plus custom conversion factors, opioid visibility and settings transfer. Your first detailed results are free to try. Available plans, prices and any introductory offer are shown using the information supplied by the App Store before purchase. Purchases can be restored in the app. CLINICAL USE Equianalgesic conversions are estimates and do not replace clinical judgement. Consider incomplete cross-tolerance, patient factors, formulation, route, local guidance and monitoring when interpreting a result. Review the references and terms of use before using the calculator in clinical practice.
