The lower eyelid is anatomically coupled to the inferior rectus (IR) muscle, so that IR recession alone causes lower lid retraction often symptomatic due to corneal exposure. Although procedures within the conjunctival incision reduce retraction slightly, cutaneous lower eyelid retractor release (CLERR) eliminates this problem.

皮肤下眼睑牵开器松解避免下直肌退缩后下眼睑错位


下眼睑在解剖学上与下直肌 （IR） 相连，因此仅 IR 后退会导致下眼睑回缩，通常是由于角膜暴露而出现症状。虽然结膜切口内的手术略微减少了回缩，但皮肤下眼睑牵开器松解术 （CLERR） 消除了这个问题。
