Summary
Adding finger force during blepharoptosis surgery precisely quantifies eyelid tension, preventing postoperative lagophthalmos. This technique ensures optimal eyelid closure after involutional blepharoptosis repair.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Eyelid Surgery
Background:
- Involutional blepharoptosis commonly requires surgical correction.
- Postoperative lagophthalmos is a potential complication of blepharoptosis surgery.
- Accurate intraoperative assessment is crucial for successful outcomes.
Purpose of the Study:
- To introduce and evaluate a novel intraoperative method for quantifying eyelid tension using finger force.
- To assess the efficacy of this technique in preventing postoperative lagophthalmos in blepharoptosis repair.
Main Methods:
- Levator resection was performed on 20 eyelids with involutional blepharoptosis.
- Intraoperative fissure height was measured.
- Finger force was applied to assess and correct lagophthalmos during voluntary eyelid closure, aiming for <2 mm.
Main Results:
- Six patients (20 eyelids) initially showed >3 mm lagophthalmos upon voluntary closure.
- After applying finger force to lower the upper eyelids, all affected eyelids demonstrated <2 mm lagophthalmos.
- No cases of lagophthalmos were observed one month postoperatively.
Conclusions:
- Intraoperative quantification using finger force allows for precise adjustment of eyelid tension.
- This technique effectively prevents postoperative lagophthalmos following blepharoptosis surgery.
