Purpose To evaluate, by laser photometry, the persistency of anterior chamber flare after uneventful phacoemulsification in asymptomatic patients with no signs of inflammation on slit lamp examination. Method Seventy-five patients previously enrolled in a randomized clinical trial that evaluated inflammation after uneventful phacoemulsification in eyes treated with dexamethasone 0.1% ophthalmic suspension (group 1) or bromfenac 0.09% ophthalmic solution (group 2) for 2 weeks. Anterior chamber inflammation was investigated by laser flare photometry. At 30 days after surgery, laser flare showed persistently elevated values. For this reason, patients were further analyzed at 3 and 6 months. Additionally, optical coherence tomography was used to measure the central macular thickness (CMT) and to assess for postoperative pseudophakic macular edema. Results When compared to preoperative values, laser flare photometry demonstrated persistent ocular inflammation at postoperative days 90 and 180 in group 1, but not in group 2. Laser flare values showed a significant reduction in group 2 compared to group 1 throughout all the follow-up (p < 0.001). The increase in mean CMT at days 90 and 180 with respect to baseline was statistically significant in group 1 but not in group 2, in which it decreased to levels similar to preoperative value. Group 1 showed a higher increase in mean CMT compared to group 2 throughout all the follow-up (p < 0.001). The proportion of patients that developed pseudophakic cystoid macular edema (CME) was 14% (n = 5) and 0% (n = 0) in group 1 and group 2, respectively (p = 0.02). The bivariate analysis demonstrated a positive correlation between laser flare and CMT values in group 1 but not in group 2. Conclusion Anterior chamber inflammation persists for more than 30 days in a significant proportion of patients after uncomplicated cataract surgery and may be responsible for late onset of cystoid macular edema cases.

Abstract
Purpose To evaluate, by laser photometry, the persistency of anterior chamber flare after uneventful phacoemulsification in asymptomatic patients with no signs of inflammation on slit lamp examination. Method Seventy-five patients previously enrolled in a randomized clinical trial that evaluated inflammation after uneventful phacoemulsification in eyes treated with dexamethasone 0.1% ophthalmic suspension (group 1) or bromfenac 0.09% ophthalmic solution (group 2) for 2 weeks. Anterior chamber inflammation was investigated by laser flare photometry. At 30 days after surgery, laser flare showed persistently elevated values. For this reason, patients were further analyzed at 3 and 6 months. Additionally, optical coherence tomography was used to measure the central macular thickness (CMT) and to assess for postoperative pseudophakic macular edema. Results When compared to preoperative values, laser flare photometry demonstrated persistent ocular inflammation at postoperative days 90 and 180 in group 1, but not in group 2. Laser flare values showed a significant reduction in group 2 compared to group 1 throughout all the follow-up (p < 0.001). The increase in mean CMT at days 90 and 180 with respect to baseline was statistically significant in group 1 but not in group 2, in which it decreased to levels similar to preoperative value. Group 1 showed a higher increase in mean CMT compared to group 2 throughout all the follow-up (p < 0.001). The proportion of patients that developed pseudophakic cystoid macular edema (CME) was 14% (n = 5) and 0% (n = 0) in group 1 and group 2, respectively (p = 0.02). The bivariate analysis demonstrated a positive correlation between laser flare and CMT values in group 1 but not in group 2. Conclusion Anterior chamber inflammation persists for more than 30 days in a significant proportion of patients after uncomplicated cataract surgery and may be responsible for late onset of cystoid macular edema cases.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
