Purpose <p>To evaluate the efficacy and safety of a modified Jones procedure using a partial-incision technique for the correction of involutional entropion.</p> Methods <p>This retrospective study included 46 eyelids from 36 elderly patients with involutional entropion. A lateral partial-incision was made to access the lower eyelid retractors without disrupting the tarsal plate or lateral canthus. The pretarsal orbicularis oculi muscle (OOM) was sutured to the lower eyelid retractor with 6-0 Vicryl sutures to correct vertical laxity and improve lid position. Operative outcomes, recurrence, complications, and patient satisfaction were recorded. Patients were followed for at least 6 months.</p> Results <p>All patients achieved satisfactory aesthetic and functional outcomes, with complete resolution of preoperative symptoms. Only 2 eyelids (4.3%) experienced recurrence during long-term follow-up. No cases of ectropion, punctum displacement, or lower eyelid retraction were observed. Intraoperative findings revealed retractor thinning without disinsertion in all cases.</p> Conclusion <p>This modified Jones procedure offers a safe, minimally invasive, and cosmetically favorable alternative for the treatment of involutional entropion. It simplifies surgical steps, preserves critical eyelid anatomy, and results in favorable outcomes with low recurrence and complication rates.</p> Level of Evidence IV <p>This journal requires that authors assign a level of evidence to each article.
