Scientific Experimentation

Determination of a product’s ability to remove compounds from the surface of contact lenses, or a product’s ability for contact lens care to be removed from the surface of the lenses.

Rinsing

Determination of a product’s ability to remove compounds from the surface of contact lenses, or a product’s ability for contact lens care to be removed from the surface of the lenses.

Cleaning

Proteins

Determination of the ability of contact lens cleaners to remove proteins (present in tears) from the lens surfaces.

Lipids

Determination of the ability of contact lens cleaners to remove lipids (present in tears) from the lens surfaces.

Physical Compatibility

In Compliance with Standards EN ISO 11981:2018.

Determination of the physical compatibility (variations in radius, power, diameter, spectral transmittance, and physical appearance) of contact lens care products with the lenses.

Symptom Relief

Determination of the ability of ophthalmic products to relieve eye symptoms through clinical trials with patients.

Usability

Verification and validation testing of ophthalmic product designs through a process of observation and collection of data gathered during the use of the product by actual users.

Post Market

Design, as appropriate, and implementation of post-marketing studies based on the collection of clinical data from the use of medical devices in humans.

Conservation

Assessment of the alteration of the physico-chemical properties (EN ISO 11981:2018 standard) of contact lenses and the growth of microorganisms (UNE-EN ISO 11978:2018/A1:2021), after long periods of storage in maintenance solutions.

Wetting

Determination of TFSQ parameters based on the ratio of contact lens dehydration with maintenance solutions and artificial tears, to improve their wearability and lubrication.

Cytotoxicity

Determination by assay, with MTT reagent, of cell viability after treatment with ophthalmic products. In accordance with Standard EN ISO 10993-5:2009.
