Abstract
A cannula device for an ophthalmic surgical procedure includes a cannula configured to be inserted through a sclera of an eye and a disk structure configured to apply a force on the sclera to sustain a position of the cannula. A cannula insertion sustaining system for an ophthalmic procedure includes a cannula tube configured to be inserted through a sclera of an eye, an upper tube portion, and a connector tube coupled to the upper tube portion and to the cannula tube. The connector tube is configured to reduce an effective pulling vector force asserted on the cannula tube. A method of sustaining a position of a cannula in a sclera includes inserting the cannula through the sclera and engaging a support structure with the sclera to apply a force on the sclera.
