Plain English Summary
Background and study aims
Lower eyelid involutional entropion causes the eyelid margin and eyelashes to rotate inward and irritate the eye. It usually occurs in individuals above 50 years of age. Many surgical methods have been designed to correct the contributing factors, but even so, recurrence is still a troublesome complication. To reduce the risk for recurrence, surgeons have modified the procedures according to the patients. The type of surgical procedure to be adopted should also be determined according to racial anatomical differences. Therefore, researchers have proposed a new surgical method modified from the Quickert procedure. This surgical design can cover most of the triggering causes in Asians. The aim of this study is to review the outcomes of patients who have undergone this surgery during the past five years (from January 2012 to October 2017).
Who can participate?
Patients aged over 55 years who had been diagnosed with involutional entropion and underwent the new surgical technique for repair
What does the study involve?
Information is collected from each patient’s medical record including surgical success, complications and recurrence. All surgical procedures and examinations are performed by a single oculoplastic surgeon (CY Chen) using consistent techniques.
What are the possible benefits and risks of participating?
The surgical procedure was modified from the Quickert procedure in some steps, and the Quickert procedure has been well confirmed in the correction of lower lid entropion. The modified surgical procedure is thought to be safe and effective, and result in less recurrence, overcorrection and complication.

July 2018 to January 2019

Involutional lower eyelid entropion
Every outpatient receiving the modified Quickert procedure is arranged regular follow-ups at the outpatient clinic at the time of pre-op, 1 week and 2 months after surgery, and then when needed according to the patient's other chronic eye diseases.
Primary outcome measure
Success rate: successful surgery was defined as a normal eyelid position at rest, and inability to induce entropion by provocative test. Success rate was measured using external eye photography and provocative test performed in clinic, measured at follow-up after 2 months, and also after 12 months for patients when needed due to their other ocular diseases
Secondary outcome measures
Measured at follow-up after 2 months, and also after 12 months for patients when needed due to their other ocular diseases:
1. Recurrence rate: recurrence defined as either the majority of eyelashes remained in contact with the globe or persistent irritation/keratitis in the presence of residual in-turned eyelashes
2. Overcorrection rate: overcorrection defined as ectropion and conjunctiva inside out
3. Complication rate: complication defined as formation of symblepharon, wound infection or wound dehiscence during the follow-up period
