Summary
Perilimbal topical anesthesia effectively manages pain during clear corneal cataract surgery. This method ensures good patient tolerance and rapid visual recovery with minimal complications.
Area of Science:
- Ophthalmology
- Anesthesia
- Surgical Procedures
Background:
- Cataract surgery is a common procedure requiring effective anesthesia.
- Topical anesthesia is preferred for its minimally invasive nature.
- Evaluating novel topical anesthetic techniques is crucial for improving patient outcomes.
Purpose of the Study:
- To assess the efficacy of perilimbal topical anesthesia for clear corneal cataract surgery.
- To evaluate perioperative pain, visual outcomes, and intraoperative complications associated with this technique.
Main Methods:
- A prospective study of 75 patients undergoing clear corneal cataract surgery.
- Perilimbal topical anesthesia administered using preservative-free lidocaine 2% via a cellulose sponge.
- Pain assessed using a 0-3 scale; visual acuity measured postoperatively; operating time recorded.
Main Results:
- 92% of patients reported minimal to no pain (score 0 or 1).
- No pain reported during critical surgical steps like iris touch or lens implantation.
- High rates of visual acuity (≥0.5) achieved within 1 day (93.6%) and 1 week (96%) post-surgery.
Conclusions:
- Perilimbal topical anesthesia is an effective and easily administered anesthetic for phacoemulsification.
- The technique provides excellent perioperative pain control and facilitates rapid visual recovery.
- It is a safe anesthetic option with no recorded intraoperative complications.
