CLEAR VISION FOR DRY EYE MANAGEMENT

Lipid Layer Assessment

High-quality imaging under diffuse lighting, using an innovative, patented approach, enables non-invasive, qualitative evaluation of lipid layer flow across the corneal surface, supporting identification of abnormalities of the lipid layer as a driver of dry eye disease. Classification is supported by comparison with the internationally recognised Dr Guillon scale¹.

Meibomian Gland Imaging and Analysis

Enhanced visualisation of gland structure supported by an extended working distance, wider field of view, enhanced depth of field, enabling improved access to the patient’s eyelids. The Meibomian glands loss can be classified using the validated, globally recognised Meiboscale by Dr Heiko Pult².

Ocular Redness Assessment

High-resolution colour imaging and motorised diaphragm enable high-quality and consistent assessment of conjunctival redness, exploiting internationally validated grading scales (Efron³ and Jenvis⁴) to support clear visual documentation, comparison over time and investigation of inflammation as a possible driver of dry eye.

Fluorescein Imaging and Video

Fluorescein imaging supports the examination of ocular surface integrity and tear film stability. Staining patterns can be assessed and compared using the international Jenvis grading scale. The same imaging and video mode can also be used to evaluate and document the fit of rigid contact lenses.
