OBJECTIVE To prevent or decrease eyelid retraction and ectropion following lower eyelid blepharoplasty. METHODS The tarsal tuck procedure was performed during lower eyelid blepharoplasty to tighten the lower eyelid. This method had been used since 1991. RESULTS After the operation, the lower eyelid was tensional and steady. The complications of eyelid retraction and ectropion were diminished. CONCLUSIONS The pathologic basis of the eyelid bag is that the supporting tissues become lax so that the lower eyelid and lateral canthus move downwards. The exact aim of the tarsal tuck procedure is to correct these pathologic changes.
