A Pilot Study of the Effect of Intravitreal Dexamethasone Implant (700 Micrograms) on Diabetic Macular Edema After Cataract Surgery
The purpose of this study is to assess the efficacy and safety of OZURDEX (dexamethasone intravitreal implant) 0.7 mg administered immediately after phacoemulsification and intraocular lens implantation in type 1 or 2 diabetic patients to prevent the occurrence of post-surgical macular edema (ME).
Treatment group: 24 patients will receive an intravitreal injection of OZURDEX at the end of cataract surgery Patients will be seen at 1 week pre-operatively (baseline visit), and on the same day post-surgery (visit 1), at 1 week (visit 2), 1 month (visit 3) and 3 months (visit 4).
BCVA, IOP and SD-OCT will be performed at each visit.
