Objective: To determine whether there is a statistically significant difference in the surgical outcome of everting sutures (ES) alone versus everting sutures with a lateral tarsal strip (ES+LTS) in the treatment of involutional entropion.
Design: Prospective randomized comparative trial.
Participants: Sixty-three patients with primary involutional lower eyelid entropion were enrolled in the study. The age range was 54 to 94 years, with a mean age of 77 years. Baseline characteristics of the comparative groups were similar.
Methods: Patients requiring primary surgical repair for involutional entropion were selected, and those providing informed consent were randomized for surgery. Thirty-six patients were randomized to ES alone, and 27 patients were randomized to ES+LTS. Patients were evaluated at 3 weeks and 6, 12, and 18 months postoperatively.
Main outcome measures: Successful surgery was defined as a normal eyelid position at rest and inability to induce entropion on tetracaine provocation testing at or before the 18-month follow-up visit.
Results: Eight patients were lost to follow-up (7 had ES alone). Of the 55 patients with complete follow-up data, there were 6 failed procedures in the patients who underwent ES alone and no failed procedures in the patients who underwent ES+LTS (P = 0.02).
Conclusions: These data provide strong evidence that success rates at 18 months are higher in patients treated with ES+LTS procedure compared with ES alone.
