EDEMA
A standard self-administered questionnaire was adopted for both groups to record the postoperative comfort of the ocular area, which was administered on postoperative days 1, 3, 5, and 7. The questionnaire assessed 10 symptoms, including photophobia, tearing, burning, pain, foreign body sensation, blurred vision, difficulty opening the eyes, dry eyes, edema, and sting. Each feature was scored from 0–3, where a score of 0 was considered asymptomatic, and scores of 1, 2, and 3 were rated as mild, moderate, and severe, respectively. The participants received a tutorial regarding the questionnaire, and the completed questionnaires were collected on the day of the re-examination.
