AIM: To evaluate the effects and complications of retractor repair combined with a lateral tarsal strip procedure and retractor repair alone for treating lower eyelid involutional entropion.

METHODS: This was a prospective study. Totally 79 cases(91 eyes)with involutional lower eyelid entropion who were hospitalized from January 2015 to February 2018 were divided randomly into observation group(41 cases 46 eyes, underwent combined procedure)and control group(38 cases 45 eyes, underwent retractor repair procedure). The clinical effects and the complications of the two groups were compared.

RESULTS: At 3mo postoperatively, there was no significant difference in the clinical effective rate(100% vs 98%, P=0.495)between the two groups. At 24mo postoperatively, the observation group had a higher clinical effective rate(98% vs 84%, P=0.030). There were no complications occurred in the observation group, significantly fewer than the control group(11%, P=0.026).

CONCLUSION: Compare to retractor repair procedure, the combined procedure has a higher clinical effective rate and a lower complications rate.
