Lash Ptosis and Entropion after Congenital Ptosis Surgery: Mechanisms and Treatment

This perspective proposes a clinically useful framework for understanding upper eyelid lash ptosis and entropion after congenital ptosis surgery, linking potential mechanisms to prevention and management.

A focused literature review was performed.

Postoperative lash ptosis and entropion likely reflect the differential interplay of multiple biomechanical factors: lamellar imbalance, suboptimal fixation geometry, tarsal buckling, excessive pretarsal dissection, and patient-specific predisposition, rather than a single technical error. Understanding these mechanisms may help surgeons anticipate risk, refine prevention, and tailor surgical management.

Lash ptosis and entropion after congenital ptosis surgery are likely multifactorial complications resulting from altered eyelid biomechanics. A mechanism-based understanding of these conditions may improve surgical planning and intraoperative decision-making. Further biomechanical and clinical studies are needed to validate this framework and optimize preventive and corrective strategies.
