Abstract: The present disclosure relates generally to small-gauge instrumentation for surgical procedures, and more specifically, to vitreoretinal instruments for retinal repair and reattachment procedures, as well as associated methods of use. Certain embodiments of the present disclosure provide a curved or articulating probe configured to provide illumination, fluid aspiration, and endophotocoagulation. Accordingly, the probe enables aspiration of subretinal fluid that re-accumulates after initial drainage and during endophotocoagulation without the need to exchange surgical instruments or insert an additional instrument into the intraocular space. Furthermore, the combined functionalities of the probe enable a surgeon to simultaneously perform scleral depression with the surgeon's other hand while aspirating fluid and/or performing retinal endophotocoagulation.
