Vitreous opacities or floaters are a common ocular condition that can cause significant impairment in vision-related quality of life (QoL) in some patients. Vitrectomy involves the surgical removal of vitreous humour, the transparent jelly, from inside the eye that contains vitreous opacities and floaters. The present post-market clinical assessment study aims to assess the safety and effectiveness performance of the Vista 1-Step vitrectomy probe in adult pseudophakic patients with visually symptomatic opacities.

Vitreous opacities or floaters are a common ocular condition that seems ubiquitous in a retina practice. Although symptoms are minimal in most patients, they can cause significant impairment in vision-related quality of life (QoL) in some patients.

Vitrectomy is a surgical procedure to remove the vitreous humour, the transparent jelly, from inside the eye. Vitrectomy Surgery can be of two types: Full and Limited. Full Vitrectomy is the commonly used and standard technique for repairing retinal detachments, removing membranes or haemorrhages, and involves vitreous detachment from the retina and its removal, both centrally and peripherally. Limited Vitrectomy is a new technique which focuses on the removal of only the central part of the vitreous or Core with the Vitreous Opacities or "Floaters" in it, and without intentionally detaching it from the retina.

The Vista Ophthalmics vitrectomy probe is a single-use vitrector intended to perform anterior/posterior vitrectomy procedures and to remove vitreous and dissect tissue in the eye. The Vista Ophthalmic's probe is designed as a stand-alone handpiece for use with ophthalmic systems.
