TS 10737 EN ISO 11979-1

TS 10737 EN ISO 11979-1 is a vocabulary standard for intraocular lenses, setting out the terms used for these ophthalmic implants and the core concepts behind their evaluation methods. In general technical context, intraocular lenses are implanted to replace or supplement the eye’s natural crystalline lens, so consistent terminology matters for product descriptions, technical communication, and comparison of data across the field.

How intraocular lens terminology is organised

The focus of this standard is the shared naming of lens types, optical characteristics, sizing concepts, and the language used in performance evaluation. In broader ophthalmic engineering, intraocular lenses may differ by construction, optical design, and fixation approach. Clear definitions help align manufacturer documentation, clinical references, and test reporting so that the same term is understood in the same way.

What the scope means in practice

According to the supplied scope, the standard covers definitions of terms related to intraocular lenses and methods for evaluating these lenses. That means it is not limited to a glossary alone; it also provides a common framework for evaluation language. The supplied information does not by itself specify detailed test conditions or numerical acceptance limits, so those particulars should only be taken from the full text of the standard.

In implanted ophthalmic devices, terms such as optical power, fixation features, haptics, and positioning describe different aspects of the same product. Distinguishing these concepts is important because it separates what the lens is from how it functions inside the eye and how it is characterised technically. Vocabulary standards like this one support consistency in design documentation and technical exchange rather than defining the lens design itself.
