Summary
Topical anesthesia offers a safe and effective alternative for clear corneal cataract surgery, comparable to peribulbar anesthesia regarding pain and complications. Patients experienced significantly better cooperation with topical anesthesia.
Area of Science:
- Ophthalmology
- Anesthesia
Background:
- Clear corneal cataract surgery is a common procedure.
- Anesthesia choice impacts patient comfort and surgical outcomes.
Purpose of the Study:
- To compare the efficacy of topical anesthesia versus peribulbar anesthesia in clear corneal cataract surgery.
- To assess patient-reported pain and intraoperative cooperation.
Main Methods:
- Prospective, double-blind, randomized clinical trial involving 36 patients.
- Bilateral cataract surgeries performed with either topical or peribulbar anesthesia.
- Pain assessed via visual analog scale; patient cooperation via motility scale.
Main Results:
- No significant difference in subjective pain between topical and peribulbar anesthesia (P > .6).
- Significantly better patient cooperation with topical anesthesia (+2.16 vs +1.11, P = .03).
- No significant differences in surgical complications between the two anesthetic techniques.
Conclusions:
- Topical anesthesia is a safe and effective alternative to peribulbar anesthesia for clear corneal cataract surgery.
- Topical anesthesia may enhance patient cooperation during the procedure.
