Comparison of the Postoperative Outcomes of Posterior Layer Advancement and Modified Iliff Suturing to Correct...

Involutional lower lid entropion is treated surgically with either incision or rotational suturing. The authors have obtained good results with the modified Iliff suture (MIS) procedure. Here, the authors compare the efficacy and postoperative outcomes of MIS and posterior layer advancement. This study included Japanese patients with a normal snap-back test, who underwent primary surgery for correcting involutional lower lid entropion, performed by the same surgeon, from April 2009 to March 2017, and who were followed up for at least 24 months postoperatively. Posterior layer advancement was performed on 50 eyelids of 48 patients (19 men, 29 women; mean age 74.1 ± 8.7 years) and MIS was performed on 50 eyelids of 40 patients (16 men, 24 women; mean age 77.3 ± 7.5 years). The authors compared the postoperative follow-up duration, recurrence rate, and operating time between groups. Postoperative follow-up duration was 34.5 ± 7.4 months in the posterior layer advancement and 32.3 ± 8.1 months in the MIS group (P = 0.180). Recurrence rate was 6% (3 cases) in the posterior layer advancement group and 4% (2 cases) in the MIS group (P > 0.999). Operating time was significantly shorter in the MIS group (5.8 ± 1.1 minutes) than in the posterior layer advancement group (31.6 ± 4.1 minutes, P < 0.001). Modified Iliff suture is less invasive than posterior layer advancement and has similar postoperative outcomes; thus, it is useful for treating involutional lower lid entropion.
