Overview
ISO 11979-8:2017 is an international standard that defines the fundamental requirements for intraocular lenses (IOLs) intended for surgical implantation in the anterior segment of the human eye. This standard excludes corneal implants and transplants, focusing specifically on ensuring safety, performance, and quality for all types of IOLs. Developed by ISO’s Technical Committee ISO/TC 172 under the subcommittee SC 7 on ophthalmic optics and instruments, this standard aligns with global medical device regulations and best practices.
This third edition replaces earlier versions and integrates technical revisions to meet evolving clinical and manufacturing demands. The standard provides a comprehensive framework for manufacturers, regulators, and clinicians involved in ophthalmic implant development and usage.
Key Topics
- Scope and Applicability: Fundamental requirements cover all intraocular lenses except corneal implants and transplants, addressing design, safety, and performance needs.
- Safety and Performance: Emphasizes the need for preclinical and clinical evaluation, including risk analysis consistent with ISO 14971 on medical device risk management.
- Optical and Mechanical Properties: Manufacturers must ensure compliance with related standards for optical quality (ISO 11979-2) and mechanical properties (ISO 11979-3), justifying any deviations.
- Biocompatibility: Establishes requirements to document biocompatibility, conforming to ISO 11979-5, highlighting the importance of using previous data or performing additional testing if necessary.
- Clinical Evaluation: Details the process for demonstrating clinical safety and efficacy, referencing ISO 14155 for good clinical practice and conditions under which clinical investigations are needed.
- Manufacturing: Specifies that production processes must maintain design specifications and safety criteria.
- Sterilization: Outlines sterilization requirements including acceptable residual levels of sterilants like ethylene oxide and bacterial endotoxins. Compliance with ISO 14630 is required.
- Packaging and Shelf Life: Packaging must protect the product stability per ISO 11979-6 and adhere to relevant regional regulations.
- Labeling and Documentation: Requires clear, compliant labeling and comprehensive documentation of design, testing, and clinical data as per ISO 11979-4 and regulatory demands.
Applications
ISO 11979-8:2017 is essential for:
- Manufacturers of Intraocular Lenses: To design, test, and produce safe, effective IOLs that meet global quality standards.
- Healthcare Providers: Ensures that implanted lenses meet established safety and performance benchmarks.
- Regulatory Bodies: Facilitates evaluation and approval processes for ophthalmic implants.
- Clinical Researchers: Provides guidance for designing clinical investigations and assessing new IOL models or modifications.
- Medical Device Auditors: Serves as a reference for audits and conformity assessments related to ophthalmic implants.
The standard supports innovations such as monofocal, multifocal, and phakic intraocular lenses, ensuring they meet stringent safety, mechanical, and optical criteria for successful vision correction surgeries.
