What form of fluorescein is preferred in the operating room to reduce contamination risk?

Fluorescein strips are preferred in the operating room primarily because they significantly reduce the risk of contamination that can occur with liquid forms of fluorescein. When using fluorescein solution or dye, there's a greater potential for spills or accidental exposure, which can not only compromise sterile conditions but also pose a risk of infection.

Fluorescein strips, on the other hand, are individually packaged, minimizing exposure to environmental contaminants. They allow for controlled and precise application, as they can be directly placed in the eye without the need to transfer liquid from one container to another. This reduces not only the likelihood of contamination but also simplifies the process, making it quicker and more efficient during surgical procedures.

While fluorescein gel may provide benefits such as prolonged staining time, its use might not be as common in procedures where sterility is paramount due to the potential for additional contamination factors introduced with, for example, the use of a gel applicator versus a simpler strip format.
