TS EN ISO 11979-1

TS EN ISO 11979-1 is the vocabulary standard for intraocular lenses, a class of ophthalmic implants used in eye surgery to replace or supplement the natural crystalline lens. Rather than specifying a product design or a test program, it establishes the shared meaning of the terms used in this field and in the evaluation methods associated with intraocular lenses.

Why precise terminology matters in ophthalmic implants

Intraocular lenses can differ in optical power, geometry, material, and optical behavior. Clear terminology helps manufacturers, clinicians, laboratories, and regulators speak about the same concept in the same way. That matters when comparing performance, reading technical documentation, or interpreting evaluation data across different lens types and studies.

What this document covers

The document contains definitions of terms related to intraocular lenses, together with definitions for terms connected to the methods used to evaluate these IOLs. It also notes that the terms are listed in alphabetical order by the English term. In other words, it is a terminology reference for this domain, supporting consistent language rather than prescribing the full mechanics of testing itself.

• Core technical terms used for intraocular lenses
• Concepts linked to methods for evaluating IOLs
