Devices for maintaining a telescope during a minimally invasive surgery (MIS) technique such as laparoscopy or thoracoscopy. A telescope maintenance assembly is comprised of a disc and a dome. The disc is absorbent and includes a central aperture. The dome is hollow and includes an inlet port, a lower protrusion, and outlet ports which abut against the disc when attached thereto. To prepare the assembly for use, the disc is secured about a proximal port of a trocar and the lower protrusion is inserted through the central aperture, and an anti-fog solution is transmitted into and through the dome to wet the disc. After the disc is wetted, the wetted disc can be used by a surgeon or assistant to wipe debris from a lens or other optical component of the telescope without needing to remove the telescope from the trocar.
