Pain during cataract surgery is linked to specific factors. Lower intraocular lens power (<19 D), chronic analgesic use, and brown or white cataracts increase pain risk. Anesthesia may need adjustment for these patients.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Cataract surgery is commonly performed under local anesthesia.
- Patient comfort and pain management are crucial during ophthalmic procedures.
Purpose of the Study:
- To identify risk factors associated with pain during cataract surgery performed under local anesthesia.
- To inform clinical practice and improve patient outcomes.
Main Methods:
- A multicentric observational study involving 330 patients undergoing cataract surgery with local anesthesia and conscious sedation.
- Pain was assessed using a numerical rating scale (NRS) after drape removal.
- Multivariate logistic regression analyzed clinical and biometric data to identify pain predictors.
Main Results:
- 13.7% of patients reported pain (NRS score ≥4).
- Significant risk factors for pain included intraocular lens (IOL) power <19 D (OR=2.78), chronic analgesic use (OR=4.34), and brown or white cataract type (OR=5.68).
Conclusions:
- Anesthesia protocols should be adapted for patients with specific risk factors: myopic eyes (IOL power <19 D), those on chronic analgesics, and individuals with brown or white cataracts.
- Further research could develop a predictive pain score for integration into biometry devices.
