ISO 11979-4:2026

Overview

ISO 11979-4:2026 sets the international standard for labelling and information requirements for intraocular lenses (IOLs), which are medical devices implanted to replace the natural lens of the eye. The document outlines the essential information that must appear on or within the packaging of IOLs, including labelling content, instructions for use, self-adhesive labels, and patient information materials. The goal is to harmonize labelling practices globally, while accommodating national variations.

This standard is vital for manufacturers of ophthalmic implants, healthcare providers, regulatory authorities, and supply chain partners concerned with device traceability, safety, and regulatory compliance in ophthalmology.

Key Topics

• Labelling Requirements

  • Mandatory information for primary and secondary packaging of IOLs
  • Use of recognized symbols (per ISO 15223-1) to simplify and clarify packaging

• Instructions for Use

  • Minimum elements required, such as device description, technical and optical data, sterilization method, handling instructions, contraindications, adverse events, warnings, and clinical investigation summary (if available)
  • Instructions may be provided electronically, subject to national regulations

• Self-Adhesive Labels

  • When supplied, must provide details including manufacturer, product model, batch/serial number, UDI code, and key device specifications such as dioptric power and dimensions

• Patient Information Materials

  • Patient information leaflets (PILs) and implant cards are required for effective communication and device traceability
  • Leaflets must be written for patient comprehension, including use, warnings, and expected outcomes
  • Implant cards enable traceability in cases of recall and post-implantation follow-up

• Special Considerations for SVIOLs

  • Simultaneous vision intraocular lenses have unique labelling needs, such as the inclusion of defocus curves and base/addition powers, reflecting ISO 11979-7 requirements

Applications

ISO 11979-4:2026 applies to stakeholders involved in the life cycle of intraocular lenses, from development and manufacture to clinical use:

• Manufacturers

  • Ensure labelling aligns with global regulatory expectations, improving market access
  • Enhance patient safety through clear, standardized information on packaging and documentation

• Healthcare Providers

  • Access comprehensive and reliable IOL information for patient counseling, surgical planning, and post-operative care
  • Utilize patient implant cards and leaflets for accurate record-keeping and patient education

• Regulators and Auditors

  • Reference a global benchmark for assessing compliance in labelling and documentation of ophthalmic implants

• Patients

  • Receive standardized, understandable information about implanted devices and aftercare

Digital documentation is increasingly accepted, as provided for under this standard, supporting modern supply chain and information management practices.
