Pain perception enhancement in consecutive second-eye phacoemulsification cataract surgeries under topical anesthesia

Area of Science:

• Ophthalmology
• Pain Perception
• Surgical Outcomes

Background:

• Cataract surgery, specifically phacoemulsification under topical anesthesia, is standard for visual impairment.
• Patients frequently report heightened pain during second-eye surgery compared to the first.
• This increased intraoperative pain negatively impacts patient satisfaction and willingness for subsequent procedures.

Purpose of the Study:

• To review current literature on pain perception differences in consecutive cataract surgeries.
• To summarize research on the mechanisms underlying enhanced pain in second-eye phacoemulsification.
• To identify potential interventions for mitigating intraoperative pain in second-eye cataract surgery.

Main Methods:

• Systematic literature search of the PubMed database.
• Focus on articles published up to February 1, 2024.
• Synthesis of findings on pain perception differences, mechanisms, and interventions.

Main Results:

• Accumulated literature indicates a trend of increased pain perception in second-eye cataract surgeries.
• Key contributing factors include immunological, neuropsychological, and pharmacological elements.
• Research is ongoing to elucidate specific mechanisms and develop targeted interventions.

Conclusions:

• Understanding the factors influencing enhanced pain perception is crucial for improving patient experience.
• Developing effective strategies to manage intraoperative pain is essential for enhancing satisfaction and adherence to treatment.
• Further research into novel interventions can significantly improve outcomes for patients undergoing bilateral cataract surgery.
