3 Terms and definitions
For the purposes of this document, the terms and definitions given in YY/T 0290.1
apply.
4 Safety and performance
The safety and performance of an intraocular lens shall be demonstrated by pre-clinical
and clinical evaluation, including suitable risk in accordance with YY/T 0316.
In cases where a test method referenced in YY 0290 is not suitable for a certain design
or a certain application, an alternative test method devised by the manufacturer shall be
validated, justified and documented.
5 Optical and mechanical properties
The manufacturer shall ensure that the intraocular lens conforms to applicable
requirements in YY 0290.2, YY 0290.3 and YY 0290.10. The manufacturer shall record
and justify any deviations from the above standards.
6 Biocompatibility
The manufacturer shall have documented evidence that demonstrates the intraocular
lens to be biocompatible by assessment in accordance with YY 0290.5.
Manufacturers can take into consideration previous experience and data when
determining the extent of further biocompatibility testing.
7 Clinical evaluation
The clinical evaluation shall be carried out in accordance with the relevant provisions
of the clinical evaluation of medical devices in our country.
Note: The first step in the clinical evaluation is a review of the available literature
(published and unpublished) in order to determine if that information is
sufficient to demonstrate the safety and performance of the device. One option
is to demonstrate that the new intraocular lens model is a minor modification of
a parent model, the safety and performance of which has previously been
