General anesthesia was used for all surgical procedures. One of the two ophthalmologists performed the surgery, and both surgeons performed identical surgeries, as described in the methods below. The incision method (modified Hotz procedure with LMS) was based on the previously described method by Hwang et al.The subcutaneous tissue of the orbicularis skin flap was fixed to the lower margin of the tarsus with three interrupted sutures using 6–0 polyglactin (Vicryl; Ethicon Inc, Somerville, NJ). Skin edges were closed using 8–0 polyglactin (Vicryl), and sutures were not removed.The nonincisional technique (buried sutures) was based on the method described by Seo et al.
