Feedback from AIO Chairman Dr Christian French:

I have been using the AVS fluorescein filter for some time and I find it an invaluable addition to my standard range of instruments. I use it in almost every eye casualty clinic I work in my hospital role, in addition to assessing and monitoring our corneal patients. In private practice, it is extremely useful in both contact lens assessments and dry eye consultations.

The free filters that we used to use are OK, but staining is so much easier to assess with the AVS filter; in addition to having both hands free to operate the slit lamp. Worth every penny and every clinician using fluorescein on their patients should have one to hand.
