    Although extra solution will be washed from your eyes, some blue color may remain for several days. Any implanted lenses may become discolored. Talk with your doctor if you experience either of these effects. In rare cases, an allergic reaction is possible, which may cause facial or throat swelling, hives, itchy rash and difficulty breathing. Your surgeon should be trained in how to handle this situation.
