Conjunctival fluid pH was measured pre‐ and post‐operatively in 16 patients suffering from senile cataract. We found a significant increase ( P < 0.05) from 7.26 ± 0.23 (mean ± SD) on the day before operation to 7.50 ± 0.23 (mean ± SD) on the first post‐operative day in the conjunctival fluid of the treated eye. Therafter a gradual decrease towards preoperative level was observed. These changes were not observed in the healthy fellow eye ( P > 0.05). No significant pre‐operative difference was shown between the two eyes. It is reasonable to assume that the composition of the transudate/exudate from the conjunctival vessels might be responsible for the changes observed.
