Clinical Trial Summary

In this study, the investigators aim to collect data regarding the efficiency and safety of two dyes used intraoperatively in vitrectomy to stain intraocular tissues. These products have the necessary approvals to use during such operation,These are NOT experimental products.


Description:

To determine efficacy and safety of MONOBLUE DUAL View and MONOBLUE ILM View (study products) vital stains during vitrectomy surgery. Both study products are CE-marked and legally marketed in Europe. The data collection will serve as Post-Marketing Clinical Follow-up according MDR provisions. Retrospective data will also be collected for the two reference products: ILM Blue® (DORC) and Membrane Blue Dual® (DORC) to serve as control. For this purpose, patient data will be used that were collected in studies S61408 (Comparative study 23G vs 27G vitrectomy), S63610 (Comparative study 27G vitrectomy vs larger gauge surgery) and S64913 (EVA Nexus Field Observation Study). The expected effect of the study products is to provide the retinal surgeon with adequate aid in visualizing the membranes involved in the retinal pathology to treat, thanks to their staining capabilities. The performance of the study products is related to the visualization of retinal tissues (ILM and/or ERM) during the vitrectomy procedure, when these tissues cannot be distinguished accurately enough without staining. Their use allows for better identification of these tissues and facilitates their removal by the surgeon. The clinical benefit of using ophthalmic dyes is to increase the patient's ability to recover anatomically and functionally by allowing more precise surgery with an effective visualization tool. Along with collecting post-marketing clinical follow-up data on the subject products, the outcomes of the present study results may be used at the UZLeuven Hospital to decide to use Monoblue ILM View and/or Monoblue Dual View as standard-of-care, replacing Membrane Blue Dual and ILM Blue.
