Summary
Topical anesthesia is as safe and effective as retrobulbar anesthesia for combined phacotrabeculectomy. This study found comparable operating conditions and patient comfort, with fewer complications in the topical group.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Combined phacotrabeculectomy is a surgical procedure for glaucoma and cataracts.
- Anesthesia choice impacts patient comfort and surgical outcomes.
Purpose of the Study:
- To compare the safety and efficacy of topical versus retrobulbar anesthesia for combined phacotrabeculectomy.
Main Methods:
- Prospective randomized study of 40 patients undergoing combined phacotrabeculectomy.
- Patients were randomized to receive either topical or retrobulbar anesthesia.
- Evaluated operating conditions, patient comfort, and surgical outcomes.
Main Results:
- No significant differences in operating conditions, pain, or need for supplemental anesthesia.
- Topical anesthesia group reported slightly more bother from touch sensation.
- Retrobulbar anesthesia group experienced more chemosis, subconjunctival hemorrhage, and eyelid hematoma.
Conclusions:
- Topical anesthesia is a safe and effective alternative to retrobulbar anesthesia for combined phacotrabeculectomy.
- Offers comparable outcomes with a potentially better safety profile regarding specific complications.
