Longitudinal slit-lamp examination indicating the progressive disappearance of limbal biopsy fragments and the emergence of complications after SLET. a At 1 week after SLET, the hAM and the limbal biopsy fragments were evident. b After 1 month, the hAM was partially absorbed, and the limbal biopsy fragments appeared with more indistinct margins. c After 2 months, few reduced-sized fragments were visible. d After 3 months, fluorescein staining showed the smooth surface of the cornea, which indicated that the corneal was epithelialized. e–g After 4, 13, and 19 months, the grafts gradually disappeared, the cornea became clearer, and the conjunctival cyst appeared and grew. h After 20 months, the cornea was clear after cystectomy
