The ARF-OCE experiment protocol of the SMILE and FLEx surgery, (a) is the SMILE surgery incision structure, the SMILE procedure preserves most of the anterior corneal stroma by creating a small 2–3 mm incision in the anterior corneal stroma and removing the stromal microcrystalline lens; (b) is the FLEx surgery flap structure, the FLEx procedure uses a femtosecond laser to create a corneal flap on the surface of the cornea and then thin the stroma.
