Abstract
PurposeThe purpose of this study was to examine the surgical outcome of posterior layer advancement of the lower eyelid retractors (LER) with transcanthal canthopexy for involutional lower eyelid entropion.Patients and methodsFifty-one eyelids of 41 patients with involutional entropion and vertical and horizontal laxities that underwent posterior layer advancement of the LER with transcanthal canthopexy were retrospectively reviewed. As a control, we also reviewed previously reported data from 47 entropic eyelids of 37 patients with vertical and horizontal laxities that were successfully corrected using LER advancement and a lateral tarsal strip procedure. Surgical success was defined as the normal eyelid position without contact of any cilia to the globe at the last follow-up examination.ResultsAll eyelids in the present study group were judged as successfully treated without recurrence after 13.9±9.2 months of follow up (mean±SD). The surgical time in the present study group (22.4±5.5 min) was significantly shorter than that in the control group (mean 31.3±4.9 min; P<0.001; Student's t-test). None of the patients showed lateral canthal deformity after surgery.ConclusionsPosterior layer advancement of the LER with transcanthal canthopexy provided complete surgical success with shorter surgical time without the risk of lateral canthal deformity. Posterior layer advancement of the LER with transcanthal canthopexy can be an option for correction of involutional lower eyelid entropion in patients with both vertical and horizontal laxities.
