Zeiss RESIGHT Disposable Lenses Evaluation Study

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.
