Purpose: To evaluate posterior and anterior segment safety of an intracameral injection of levofloxacin 0.5% ophthalmic solution as prophylaxis for patients undergoing cataract extraction and intraocular lens implantation.
Setting: This study was conducted at Manila Doctors Hospital, Ermita, Manila, Philippines.
Design: This was a prospective interventional study.
Methods: Eyes undergoing standard phacoemulsification cataract surgery with intraocular lens implantation were treated with intracameral levofloxacin 0.5% at the conclusion of surgery. Safety parameters, including best-corrected visual acuity (BCVA), endothelial cell counts, anterior chamber cells and flare, and central foveal thickness, were evaluated preoperatively and at 1 day and 1 week postoperatively.
Results: A total of 50 eyes of 50 patients were included in the analysis. At 1 week postoperatively, all eyes demonstrated BCVA of 20/30 or better and 19 eyes (38%) achieved BCVA of 20/20 or better. On the first postoperative day, no corneal edema was observed, and trace to +2 cells and flare in the anterior chamber were noted in all eyes. After 1 week, all eyes had a quiet anterior chamber and endothelial cell counts decreased by an average of 225 cells/mm2, which was marginally significant (p=0.0525) when compared to other time points. Optical coherence tomography results showed no statistically significant differences between central foveal thickness measurements before and after surgery. There were also no statistically significant differences in preoperative and postoperative pachymetry. No study-related adverse events occurred.
Conclusion: There were no safety concerns associated with intracameral injection of levofloxacin 0.5%, prophylactically, following cataract surgery. Further study is required to demonstrate effectiveness in endophthalmitis prevention.
