ZEISS Balanced Salt Solution (BSS)

For intraocular use


Intraocular structures, especially the endothelium, are exposed to great stress during ophthalmological surgical interventions. The use of balanced irrigation solution can help to minimize this exposure. It can replace the aqueous humor and vitreous body for the anatomical and physiological maintenance of ocular tissues in surgery.

Irrigation solution such as ZEISS Balanced Salt Solution, PURI CLEAR is physiologically similar to the aqueous humor and vitreous body and thus, it can offer excellent protection for the sensitive structures of the eye during intraocular procedures.
