Examinations and follow-up
SECONDARY
Randomization and preoperative examination were performed 1 month before the surgery. The examination included visual acuity, refractive examination using an auto refractometer, slit-lamp examination with fluorescent staining, and capturing the eyelid photographs. After surgery, both groups were followed up at 4 ± 1 weeks and 26 ± 4 weeks. At both follow-up visits, the same examinations were performed as those before the surgery. The primary and secondary outcomes were evaluated 6 months after the surgery.
