5 Key Takeaways
-
1
Vital dyes are essential for diagnosing dry eye disease and assessing contact lens fit, as recommended by the Tear Film & Ocular Surface Society.
-
2
Fluorescein sodium (NaFl) is used for corneal staining and is effective for identifying epithelial irregularities and assessing contact lens relationships.
-
3
NaFl can be applied directly to the eye after contact lens settling and is available in standard and high molecular weight formulations.
-
4
Lissamine green (LG) aids in identifying dry eye disease and stains damaged conjunctival cells, particularly useful when corneal staining is absent.
-
5
A combination of 2% NaFl and 1% LG provides optimal staining for ocular surface assessment without causing irritation.
