    Participants will have the PDS implant (filled prior to implantation with approximately 20 microlitres \[uL\] of the 100 milligrams/millilitres \[mg/ml\] formulation of ranibizumab \[approximately 2 milligrams (mg) dose of ranibizumab\]) surgically inserted in the study eye at the Day 1 visit following their enrollment visit. After the initial fill of the implant with ranibizumab, participants will receive implant refill-exchanges at fixed Q24W intervals.

    Device: PDS Implant With Ranibizumab 100 mg/ml · Drug: LUCENTIS (Ranibizumab Injection)

Interventions

  • DevicePDS Implant With Ranibizumab 100 mg/ml

    Ranibizumab 100 mg/mL will be delivered via PDS

  • DrugLUCENTIS (Ranibizumab Injection)

    Ranibizumab (0.5 mg intravitreal \[IVT\] injections of 10 mg/mL formulation) will be used in the study eye as supplemental treatment. If a participant discontinues study treatment, he/she may start receiving IVT ranibizumab injections in the study eye, per investigator's discretion.
