Tenon's capsule (/ t ə ˈ n oʊ n /), also known as the Tenon capsule, fascial sheath of the eyeball (Latin: vagina bulbi) or the fascia bulbi, is a thin membrane which envelops the eyeball from the optic nerve to the corneal limbus, separating it from the orbital fat and forming a socket in which it moves.
A singular 10-0 vicryl suture can secure the scleral flap and then the cheesewire suture can then be cut flush to the conjunctiva. The conjunctiva flap can be then secured with 26 10-0 vicryl sutures at either end of the limbus. A single 10-0 vicryl mattress suture can be placed in the middle. This entire process allows for blebs to be rescued. [5]
