Small stab wound in skin in lateral border of lid crease is made with eversion of upper lid; 2 small hemostats are clamped across superior tarsus, inferior Mller muscle, and conjunctiva (avoiding imbrication of skin and levator aponeurosis); 6Ð0 mattress suture is run 1 mm above hemostats, which are then removed; and tissue is resected at crush line. Suture is then run from medial to lateral to rejoin superior tarsal edge to inferior Mller muscle.
