Conditions

Diabetic Macular Edema, Cataract

Brief summary

The primary objective of this study is to compare the efficacy of antecedent intravitreal anti-vascular endothelial growth factor therapy vs. Ozurdex in reducing post-cataract surgery related macular edema in patients with pre-existing diabetic macular edema.

Detailed description

In patients with pre-existing diabetic macular edema, anti-vascular endothelial growth factor therapy (Bevacizumab, ranibizumab, or aflibercept) will be compared to Ozurdex therapy administered 1 week prior to phacoemulsification cataract extraction. Spectral domain optical coherence tomography and visual acuity will be acquired at 1 week, 1 month, 2 months, and 3 months following cataract surgery.

Design outcomes

Primary

MeasureTime frameDescription
Comparison of central foveal thickness outcomes of anti-vascular endothelial growth factor vs. Ozurdex therapy3 months after cataract surgeryCentral foveal thickness will be measured in microns by spectral domain optical coherence tomography (Heidelberg) and compared to baseline at post-operative week 1, postoperative month 1, postoperative month 2, and postoperative month 3 for both anti-vascular endothelial growth factor and Ozurdex groups

Secondary

MeasureTime frameDescription
Visual acuity outcomes of anti-vascular endothelial growth factor vs. Ozurdex therapy3 months after cataract surgerySnellen visual acuity will be measured and converted into logMAR and compared to baseline at post-operative week 1, postoperative month 1, postoperative month 2, and postoperative month 3 for both anti-vascular endothelial growth factor and Ozurdex groups
