Intravitreal dexamethasone implant for macular edema following uncomplicated phacoemulsification

Purpose: To retrospectively study the efficacy of a single 0.7-mg dexamethasone intravitreal implant in eyes with refractory macular edema secondary to uncomplicated phacoemulsification and intraocular lens implant. Methods: In 11 eyes of 11 consecutive patients with persistent refractory macular edema, secondary uncomplicated cataract extraction, and intraocular lens implant, the injection of 0.7-mg dexamethasone implant was performed at the Clinica Oculistica, University of Bari, Italy. Best-corrected visual acuity (BCVA), central retinal thickness measured by spectral-domain optical coherence tomography, and intraocular pressure (IOP) was evaluated at baseline, 1 month, and 6 months. Results: After a mean follow-up of 6.27 ± 0.47 months, BCVA was significantly increased from 20/40 to 20/22 (p<0.0001), mean central retinal thickness decreased significantly from 462 ± 100 to 276 ± 8 μm (p<0.0001), and IOP did not change significantly (p = 0.053). In no case were postoperative complications observed. Conclusions: A single injection of 0.7-mg dexamethasone intravitreal implant was effective in the treatment of persistent refractory macular edema secondary to uneventful phacoemulsification and in-bag lens implant. © 2013 Wichtig Editore.
