To evaluate the intra-operative efficacy of a new intra-operative viewing device.

This study is designed to obtain more information on the efficacy of the disposable RESIGHT lenses in routine vitrectomy surgery. This information can lead to adjustments to these surgical lenses to further fine tune a device which can be used by other surgeons.

Theoretically, both the improved lens design and better resistance to fogging should improve the visualization of the retina hence facilitate the surgery, increasing the surgical safety.

Inclusion Criteria:

• Voluntary written informed consent of the participant or their legally authorized representative has been obtained prior to any screening procedures
• Patients that are scheduled for primary vitrectomy surgery to treat retinal detachment or macular disease (pucker, macular hole, vitreomacular traction).
• Both vitrectomy-only and combined phaco-vitrectomy surgeries
• General or local anesthesia, or combination

Exclusion Criteria:

• Patient who do not have sufficient command of the Dutch language to read and understand the informed consent form
• Any disorder, which in the investigator's opinion might jeopardise participant's safety or compliance with the CIP.
• Repeat vitrectomy surgery
