PURPOSE: To report intraoperative quantification using finger force for involutional blepharoptosis, which helps in the prevention of postoperative lagophthalmos.
METHODS: We carried out levator resection on 20 involutional blepharoptic eyelids. Fissure height was examined intraoperatively to evaluate the extent of resection. If a patient presented more than 3 mm of lagophthalmos in voluntary eyelid closure but could fully open the eye, we forcibly closed the eyelid, using a finger, after voluntary eyelid closure. If more than 3 mm of lagophthalmos was still observed after forced eyelid closure, we corrected eyelid tension until lagophthalmos became less than 2 mm.
RESULTS: Six of the ten patients (20 eyelids) presented with full eyelid opening but more than 3 mm of lagophthalmos in voluntary eyelid closure. After the upper eyelids were forcibly lowered, all six eyelids showed less than 2 mm of lagophthalmos. There were no cases of lagophthalmos 1 month postoperatively.
CONCLUSIONS: Additional finger force makes precise quantification of blepharoptosis surgery possible and prevents postoperative lagophthalmos.
