Does Repeated Irrigation of Operative Field With Betadine During Cataract Surgery Reduce Anterior Chamber Bacterial Contamination?

January 21, 2011

From the American Journal of Ophthalmology comes a study designed to test whether repeated irrigation of the operative field with povidone–iodine of 0.25% during cataract surgery reduces the anterior chamber bacterial contamination rate at completion of operation.

Surgeons irrigated the eye surface every 20 seconds with 0.25% Povidone-Iodine, and demonstrated zero (!) bacterial detection in the anterior chamber compared to controls (5%). No changes in corneal endothelium were found.

It is not a stretch to say that endophthalmitis rates will be much lower- maybe even zero- if this cheap, easy method were employed.
