Brief summary
This study aims to examine the effectiveness of multimedia health education in reducing preoperative anxiety and enhancing self-care awareness among patients undergoing outpatient cataract surgery. A randomized group design will be employed, in which participants will receive either standard preoperative education or a multimedia-based intervention covering surgical procedures, precautions, and postoperative care. Primary outcomes include levels of surgical anxiety, assessed using validated anxiety scales, and self-care knowledge evaluated through structured questionnaires. Findings are expected to inform the development of patient-centered educational strategies and enhance perioperative care quality in cataract surgery settings.
Detailed description
This randomized controlled trial aims to evaluate the effectiveness of multimedia health education in reducing preoperative anxiety and improving postoperative care awareness among patients undergoing outpatient cataract surgery. A total of 118 patients scheduled for cataract surgery at an ophthalmology outpatient clinic will be randomly assigned to either the control group or the intervention group. All participants will receive standard verbal preoperative instructions from their physician. In addition, the intervention group will view a 10-minute multimedia video covering the surgical procedure, precautions, and postoperative care. Baseline data-including demographics, visual acuity, physiological anxiety indicators, the Beck Anxiety Inventory (BAI), and a cataract-specific self-care knowledge questionnaire-will be collected during the final preoperative clinic visit. Outcome data will be collected at three time points: before surgery, one week after surgery, and one month after surgery. Primary outcomes include changes in anxiety levels and self-care knowledge; secondary outcomes include physiological responses during surgery and postoperative visual recovery. The results are expected to support the use of multimedia education to enhance patient preparedness and care quality in cataract surgery.
Interventions
BEHAVIORALMultimedia Health Education
A 10-minute multimedia video is provided to the intervention group during their final preoperative clinic visit. All participants receive standard verbal and printed education from the ophthalmologist. The video includes visual and auditory content on cataract surgery, preoperative instructions, postoperative care, and common concerns. Baseline data (T0) are collected before the intervention, including demographics, visual acuity, physiological indicators, BAI, and self-care knowledge. Follow-ups occur at T1 (surgery day), T2 (1 week postop), and T3 (1 month postop), assessing anxiety, physiology, vision, and self-care.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in anxiety levels measured by the Beck Anxiety Inventory (BAI) | Time Frame: Day 0 (baseline, preoperative clinic visit), Day of Surgery, 1 Week Postoperative, 1 Month Postoperative | Participants will complete the Beck Anxiety Inventory (BAI), a 21-item self-report questionnaire used to assess the severity of anxiety symptoms. The total score ranges from 0 to 63, with higher scores indicating greater levels of anxiety. Specifically, scores from 0-7 suggest minimal anxiety, 8-15 mild anxiety, 16-25 moderate anxiety, and 26-63 severe anxiety. The BAI will be administered at baseline and at three follow-up points. |
| Change in self-care knowledge related to cataract surgery | Time Frame: Day 0 (baseline, preoperative clinic visit), Day of Surgery, 1 Week Postoperative, 1 Month Postoperative | Participants will complete a structured questionnaire designed to evaluate their knowledge of postoperative cataract care. Scores will be compared across time points to determine the impact of multimedia education. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in heart rate | Time Frame: Day 0 (baseline, preoperative clinic visit), Day of Surgery | Physiological indicators such as heart rate will be collected at designated time points to objectively assess anxiety responses. |
| Change in visual acuity following cataract surgery | Time Frame: Day 0 (baseline, preoperative clinic visit), 1 Week Postoperative, 1 Month Postoperative | Visual acuity will be measured using a standard eye chart at follow-up to assess postoperative recovery. |
| Change in blood pressure | Day 0 (baseline, preoperative clinic visit), Day of Surgery | Systolic and diastolic blood pressure (mmHg) will be recorded at baseline and on the day of surgery as objective physiological indicators of anxiety. |
