Technique of tenon patch graft. (A) Size of the corneal perforation and the area of thinning is measured using calipers. (B & C) Conjunctiva in supero-temporal quadrant is marked 1 mm more than the measured size of the thinning. (D) A linear peritomy is done over the marked area. (E) Separated tenon tissue is marked and measured using calipers. (F) A linear incision is made over the tenon tissue extending to the underlying episcleral tissue using a curved vanna’s scissors. (G) The tenon tissue corresponding to the size of conjunctival marking is excised with the help of vanna’s scissors. (H) The cut edges of conjunctiva are approximated, by applying firm pressure with the help of serrated forceps, for a few seconds to achieve firm adhesion. (I) The procured graft is trimmed to match the size and shape of the defect. (J) The graft is then sutured with the help of multiple interrupted 10-0 monofilament nylon sutures. (K) The suture is first passed through the edge of the graft then through the stromal pocket and then taken out from the host cornea. (L) At the end of the procedure, anterior chamber is formed with air.
