Abstract
An eyelids opening device with a drape comprising a flexible upper ring () applied in contact with the face while surrounding eyelids, a lower ring () inserted into a conjunctiva sac and applied in contact with the eyelids conjunctiva side, and an elastic sheet () of soft tubular thin film located to extend from the face side to the eyelids conjunctiva side and used to fix one end to the upper ring and to fix the other end to the lower ring by expanding, wherein the outside diameter at the smallest portion of the elastic sheet is substantially equal to or longer than the interpalpebral length (between upper and lower eyelids). Difference in size of conjunctiva sac or interpalpebral length of individuals is absorbed even by an appliance of one size, the eyelids can be opened by fitting the eyelids opening device to the eyelids or the face while burden on the eyeball is reduced and high safety is ensured.
