Summary
Most patients undergoing cataract surgery retain vision and may experience visual sensations, sometimes causing fear. Preoperative counseling is crucial to manage patient anxiety and improve satisfaction during the procedure.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Most patients (80-100%) retain light perception during cataract surgery under local anesthesia.
- Visual sensations can include movements, colors, and surgical sights.
Purpose of the Study:
- To highlight the clinical significance of intraoperative visual sensations during cataract surgery.
- To emphasize the impact of these sensations on patient anxiety and surgical outcomes.
Main Methods:
- Literature review of patient experiences during cataract surgery under various local anesthesia techniques (regional and topical).
Main Results:
- 3-16.2% of patients reported frightening visual experiences, leading to fear and anxiety.
- Fear can cause patient uncooperativeness, sympathetic stress response, and decreased satisfaction.
- Elderly patients with comorbidities are particularly vulnerable to adverse effects.
Conclusions:
- Anesthesia providers must acknowledge retained visual function during cataract surgery.
- Preoperative counseling is effective in reducing patient fear and anxiety.
- Informed patients are more likely to have a positive surgical experience and better outcomes.
