Alcohol liberates dye of syringes

Foreign particles may contaminate intraocular surgery and have a role in postoperative inflammation. Irrigation solutions, viscoelastics, air and instruments introduced into the eye may carry in a number of organic or inorganic, inert or reactive foreign material. Dye of colored indicators on syringes may also behave as an unrecognized contaminant. This dye material is easily released from syringes by exposure to alcohol. The significance of dye contamination and possible outcomes were discussed.
