About this study

Researchers are testing a new way to deliver ranibizumab (a medication) into your eye, called the Port Delivery System (PDS), compared to regular injections. The trial also looks at how safe it is to re-implant the PDS after it's been used before. Participants with diabetic macular edema will receive either the PDS or standard injections every 24 weeks.

Based on ClinicalTrials.gov records.

What participants do

  • 1.Receive Intravitreal Ranibizumab 0.5 mg Injection
  • 2.Take PDS Implant Pre-Filled with 100 mg/mL Ranibizumab
  • 3.Take Ranibizumab refill exchange
