Summary
Circumferential perilimbal anesthesia effectively managed pain during long cataract and glaucoma surgeries. This technique provided ample anesthesia for these complex anterior segment procedures.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Combined cataract and glaucoma surgeries are lengthy anterior segment procedures.
- Effective anesthesia is crucial for patient comfort and surgical success during these complex operations.
Purpose of the Study:
- To evaluate the effectiveness of a topical-subconjunctival anesthesia technique, circumferential perilimbal anesthesia, for combined cataract and glaucoma surgery.
Main Methods:
- The circumferential perilimbal anesthesia involved topical 4% Xylocaine drops and a 0.25 cc subconjunctival injection of 4% Xylocaine.
- The anesthetic was spread 360 degrees around the limbus using forceps.
- Intravenous sedatives and analgesics supplemented the local anesthesia.
Main Results:
- All 34 patients underwent successful phacoemulsification cataract extraction with intraocular lens and trabeculectomy.
- Average surgery duration was 46 minutes (range 35-60 minutes).
- Only one patient reported intraoperative pain.
Conclusions:
- Circumferential perilimbal anesthesia is an effective anesthetic technique for extended combined cataract and glaucoma surgeries.
- The technique ensures adequate anesthesia for complex anterior segment procedures.
