Conditions

Neovascular age-related macular degeneration (nAMD) and with diabetic macular edema (DME)

Interventions

Ranibizumab: After surgical insertion of an implant filled with ranibizumab filling solution into the study eye using an implant tool, the ranibizumab filling solution will be refilled directly into t

Inclusion criteria

Inclusion criteria: Inclusion Criteria for Patients with Neovascular Age-Related Macular Degeneration - Initial diagnosis of nAMD within 18 months prior to the screening visit - Previous treatment with at least three anti-VEGF intravitreal injections for nAMD per standard of care within 6 months prior to the screening visit - Demonstrated response to anti-VEGF intravitreal injections for nAMD - BCVA of 34 letters or better (Snellen equivalent: 20/200 or better ) Inclusion Criteria for Patients with Diabetic Macular Edema - Diagnosed with diabetes mellitus (Type 1 or Type 2) - HbA1c level =325 mcm at screening and at a run-in visit (if run-in required) - BCVA score = 78-25 letters (Snellen equivalent: 20/32 to 20/320)

Exclusion criteria

Exclusion criteria: Exclusion Criteria for Patients with nAMD - Uncontrolled blood pressure - History of other disease, metabolic dysfunction, physical examination finding, or laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of the IMP and that might affect interpretation of the results of the study or renders the patient at high risk of treatment complications in the opinion of the investigator - Current systemic treatment for a confirmed active systemic infection - Chronic use of oral corticosteroids - History of vitreous surgery, submacular surgery, or other surgical intervention for nAMD - Previous laser (any type) used for AMD treatment in study eye - Previous intraocular device implantation - Subretinal hemorrhage that involves the center of the fovea - Subfoveal fibrosis or subfoveal atrophy Exclusion Criteria for Patients with DME - Active endophthalmitis (Grade 1 or above) - Uncontrolled ocular hypertension or uncontrolled glaucoma or (in the investigator's opinion) a possibility that the patient might require a minimally invasive glaucoma surgery surgery during the study - Uncontrolled blood pressure
