Having been researching the use of fluorescent light/dyes I've come to the conclusion that they are much more effective than white light. And it is not just the companies behind it who say this - there are numerous university studies using different solutions that confirm the effectiveness of fluorescent diagnoses:

Why isn't its usage more widespread?
1. More expensive?
2. It takes longer - patient turnaround in surgery?
3. Ignorance?
I can't access some of the later medical papers but would love to see some of your opinions on this. Thank you!
article excerpt:
In April 2011 a new publication on Hexvix® in British Journal of Urology (BJUI) was published. This study confirm the results from a large prospective international study published in the Journal of Urology in November 2010. The results of the trial demonstrate that Hexvix identified lesions, including residual tumours, that were not detected with white light alone in 49% of the patients. It also demonstrated that the improved detection of lesions resulted in a significant reduction in tumour recurrence within 12 months. [8] [9]
On 12th May 2011 it was announced results from a clinical study included retrospective follow up from 526 patients in a prospective randomized Phase III trial in 28 centers in EU and North America. After a follow-up period up to 5.5 years, the number of patients who have experienced recurrence of their bladder cancer is lower, and the time it takes before the recurrence occurs is longer when they had Hexvix-guided fluorescence cystoscopy.
