Goals of the study are to evaluate how peri-operative versus intra-operative anti-VEGF
intravitreous injections affect visual acuity (BCVA) in patients with persistent diabetic
macular edema who are undergoing cataract surgery; and to evaluate how peri-operative versus
intra-operative anti-VEGF intravitreous injections affect OCT CSF thickness and total number
of postoperative injections in patients with diabetic macular edema who are undergoing
cataract surgery.
