A study on postural care after macular hole surgery based on a novel positioning sensor

Area of Science:

• Ophthalmology
• Medical Devices
• Surgical Recovery

Background:

• Idiopathic macular hole (IMH) surgery requires specific postoperative positioning, typically face-down, to promote healing.
• Maintaining effective prone positioning is crucial for successful surgical outcomes.
• Current methods for monitoring patient positioning can be subjective and lack real-time data.

Purpose of the Study:

• To evaluate the application and effectiveness of a novel postoperative positioning sensor device with real-time dynamic feedback after IMH surgery.
• To analyze the distribution of effective prone time during the first 24 hours post-surgery.

Main Methods:

• A prospective study involving 18 participants undergoing IMH surgery.
• Patients wore a positioning sensor device for 1 day postoperatively to record cumulative effective face-down position (FDP) time.
• Statistical analysis was performed to compare FDP times across different postoperative intervals.

Main Results:

• The mean total effective FDP time was 9.3 hours (SD = 4.0).
• Significant differences were observed in effective FDP times during the first, middle, and last 8-hour intervals (p < 0.001).
• The first 8 hours showed significantly more effective FDP time compared to the middle and last 8 hours (p < 0.01).

Conclusions:

• The novel positioning sensor device is well-accepted by patients and aids in postoperative care following IMH surgery.
• The device provides valuable data on effective prone positioning, highlighting significant variations within the first postoperative day.
• Real-time dynamic feedback from the sensor can help optimize patient adherence to prescribed positioning regimens.
