Objectives

Narrative objectives1

In order to achieve proper stain, DMEK surgeons all over the world commonly use trypan blue (TB). However, TB is believed to have a toxic effect on both the cornea and retina. Recently, brilliant blue G (BBG) has been recognized as an alternative for vitreoretinal surgery due to indications of lower levels of toxicity. We prospectively analyze the effect of BBG in DMEK.
