Brief summary

The objective of this study is to obtain an additional 36 months of safety and effectiveness data from all subjects who were implanted with the VisAbility™ Micro Insert in the VIS-2014 clinical trial.

Detailed description

VIS-2014-5YR is a multicenter, observational study to evaluate the long-term safety of the VisAbility™ Micro Inserts in subjects who were implanted with the VisAbility™ Micro Insert in the VIS-2014 clinical trial. Study subjects will be examined at 36, 48, and 60 months post-operatively (based on the anniversary of their first VisAbility™ surgery) with no planned interventions.

Interventions

DEVICEVisAbility™ Micro Insert

No (new) intervention will be administered during the course of this long term follow-up study. Subjects that previously participated in the VIS-2014 clinical trial that had VisAbility™ Micro Inserts surgically implanted in the eye(s) will be followed prospectively.

Participant flow

Recruitment details

Recruitment occurred at 13 clinical sites and consisted of contacting all subjects who were implanted or explanted in Protocol VIS-2014, a prospective multicenter clinical trial of the VisAbility Micro Insert System. If inclusion criteria was met, subjects who wished to participate provided written informed consent and were enrolled in this VIS-2014-5YR multicenter observational long-term study.

Pre-assignment details

Per the protocol, primary and secondary safety outcome analysis was performed on all eyes of enrolled subjects that were implanted or explanted with the VisAbility Micro Insert System in the VIS-2014 clinical study. Secondary effectiveness analysis was performed on the primary eye of only those subjects who were bilaterally implanted (with all eight implants in place) in the VIS-2014 study, therefore, the primary eye is the unit of analysis for the secondary effectiveness outcome.
