Objective: To evaluate the relation between pain complaints aftercataract surgery and phacoemulsification parameters.Materials and Methods: This prospective study was based onstudies of 94 eyes across 47 patients, who underwent cataractsurgery at 15 day intervals. The mean values of nucleus grade, totalduration of surgery, U/S total time, U/S total equivalent powerin foot position 3, cumulative dissipated energy, phacoemulsificationtime, average phacoemulsification power and averagephacoemulsification power in foot position 3 were recorded. Patientswere asked to score their pain on the first day, after the firstweek and after the first month following surgery on each eye.Results: The mean nucleus grade, cumulative dissipated energy, andU/S total time were found significantly higher in the first eye comparedwith the second eye (p= 0.01, 0.016, and 0.03, respectively).There was no statistically significant difference in mean operationtime, phacoemulsification time, U/S total equivalent power position3, average phacoemulsification power and average phacoemulsificationpower position 3 between the first and second eyes. Althoughthere was no statistically significant difference in pain scores betweenfirst and second eyes on the first postoperative day and first month,there was a significant difference at one week (p=0.080, 0.269 and0.004, respectively). There was no correlation between phacoemulsificationparameters and pain scores after both surgeries.Conclusion: This study showed no correlation between thephacoemulsification parameters and postoperative pain scoresafter both first and second surgeries. In addition, there was a significantdifference between the pain scores of the first and that ofthe second surgery at the first postoperative week.
