Summary

This trial is to study the safety, tolerability, and feasibility of using a dexamethasone-eluting contact lens to treat cystoid macular edema.

Who is the study for?
Adults aged 18-85 with recurrent cystoid macular edema who've previously responded to steroid treatments can join. They must have specific levels of visual acuity and retinal thickness, and not be at the intravitreal injection phase or beyond. Pregnant women or those on certain medications like systemic steroids are excluded.
What is being tested?
The trial is testing a dexamethasone-eluting contact lens for safety, tolerability, comfort, and feasibility in treating recurrent cystoid macular edema. Participants will wear this therapeutic lens to see if it effectively delivers medication directly to the eye.
What are the potential side effects?
Potential side effects may include discomfort from wearing contact lenses, possible ocular adverse events such as increased eye pressure or infection risk identified by regular eye examinations throughout the study period.
