[Prevention of peroperative miosis: comparison between prostaglandin inhibitors. Sodium diclofenac and indomethacin in local application]. / Prévention du myosis peropératoire: comparaison des inhibiteurs de prostaglandines. Diclophénac sodium et indométhacine en application locale.

Diclofenac sodium 0.1% (Voltaren) prevents surgically induced miosis during extracapsular cataract extraction in a more long lasting way than indomethacin 1% (Indocid). Just before the IOL-implantation, in eyes treated with diclofenac sodium eye drops, the apparent mean pupil size was constricted by approximately 1 mm less than in the control group (p.01). At the same critical moment, 50% of the pupils treated with diclofenac sodium and only 20% of the pupils in the control and indomethacin groups were larger than 6 mm.
