    Dear Editor,

    We thank Dr. Camras for his interest in our report on levels of bimatoprost and its free acid in the aqueous humour of cataract patients after a single topical dose of bimatoprost [1] and welcome the opportunity to respond to his comments. We are in agreement with Dr. Camras that the results of our study [1] and those of his previously reported study [2] are similar, showing low nanomolar concentrat...

This important study confirms the results found in previous studies.(2,3) However, despite providing important confirmat...
