Abstract
• Preoperative and postoperative anterior chamber reactions in a series of patients who had undergone cataract surgery were measured with a laser flare/cell meter (Kowa FC-1000, Kowa Instrument Corp, Japan) by two different technicians (A.M. and T.M.M.), and clinical assessments of inflammation were recorded. The average cell and flare readings of the two technicians were nearly identical at every time point, showing the laser flare/cell measurements to be highly reproducible. The correlations between laser flare/cell measurements and clinical assessments at postoperative time points were all highly positive (P<.01), demonstrating the validity of the laser flare/cell measurements.
