What is TWIN?

TWIN is 0,18% Trypan Blue + 0,03% Blulife (patented dye with formula: C48H50N3NaO7S) in physiological solution, packaged in prefilled syringes of 0,7 ml each, for reversible staining of the retinal membranes and the inner limiting membrane (ILM) to be removed during vitreoretinal surgery. The product warrants a prompt and effective tissue staining, without any risks for the patient. It contains a thickening agent that improves the contact between the dyes and the tissues, thus allowing a clear visualization of the retinal membranes and the inner limiting membrane. In addition, it simplifies the surgery, making superfluous the fluid/air exchange performed before the dye injection, in order not to dilute it.

TWIN is a product tested for cytotoxicity on ARPE-19 and BALB 3T3 cells, whose results are shown on the confirmation of use labels inside the package for a correct information to the surgeon and an increased safety for the patient.
