A conjunctival flap is a surgical procedure that involves the use of conjunctival tissue to repair or cover defects in the cornea, particularly in cases of corneal ulcers. This procedure can be performed as either a partial or total flap, depending on the extent of the corneal damage. The conjunctiva is the thin, transparent membrane that covers the white part of the eye and the inner surface of the eyelids. In the case of a partial conjunctival flap, referred to as a bridge flap, a section of the conjunctiva is carefully excised and repositioned to cover the affected area of the cornea. The procedure begins with the administration of anesthetic eye drops to ensure patient comfort. An eye speculum is then inserted to keep the eye open during the surgery, allowing the surgeon to access the cornea effectively. Diseased tissue is excised, and the size and location of the corneal defect are evaluated to determine the optimal configuration for the flap. A subconjunctival injection of lidocaine and epinephrine is administered to elevate the conjunctiva, facilitating the creation of the flap. The flap is then raised, mobilized, and rotated over the corneal defect, ensuring that its blood supply is preserved. Finally, the flap is secured in place with sutures, promoting healing and recovery of the corneal surface.
