Preoperative topical flurbiprofen-Na+ in extracapsular lens extraction role in maintaining intraoperative pupillary dilatation.
Induction of intraoperative pupillary constriction, is predominantly a prostaglandin mediated process. The most potent antiprostaglandin NSAID, Flurbiprofen was used topically to study its efficacy against the above. In a prospective double blind clinical study, 50 brown eyes undergoing planned E.C.C.E., the pupils were dilated with 10% phenylephrine and 2% homatropine 1%/tropicamide. 25 eyes received 0.03% Flurbiprofen-Na+ eye drops 1/2 hourly starting two hours before surgery. The maintained intraoperative mydriasis in the two groups before anterior chamber entry (stage I) vs at the end of complete cortex wash (stage III) was: in control group (stage I) 8.46 +/- 0.48 mm vs (stage III) 3.56 +/- 0.43 mm (highly SS); in flurbiprofen group (stage I) 8.60 +/- 0.48 mm vs (stage III) 8.01 +/- 0.63 mm (NSS). The pupillary area available for surgical manipulation in the control group was significantly decreased from 56.18 mm2 in state I to 9.94 mm2 in stage III, while in flurbiprofen group it changed insignificantly from 58.05 mm2 in stage I to 50.24 mm2 in stage III. Postoperatively after cataract was observed in 44% eyes of control group as compared to only 8% of eyes of flurbiprofen group. Thus a maintained intraoperative mydriasis in flurbiprofen group led to better E.C.L.E. which is a mandatory prerequisite to preferred and better present day posterior chamber IOL implantation.
