Summary
A combined topical and subconjunctival anesthesia technique for cataract surgery proved highly effective, with 95% of patients reporting no pain. This safe, cost-effective method avoided the need for additional anesthesia.
Area of Science:
- Ophthalmology
- Surgical Anesthesia
Background:
- Cataract surgery requires effective anesthesia.
- Traditional methods may have limitations or side effects.
Purpose of the Study:
- To evaluate the safety and efficacy of combined topical anesthesia (TA) and subconjunctival anesthesia (SCA) for scleral tunnel phacoemulsification cataract surgery.
- To assess patient-reported pain and the need for supplementary anesthesia.
Main Methods:
- A prospective study of 73 patients undergoing cataract surgery.
- Utilized a combined TA and SCA technique.
- Collected preoperative, intraoperative, and postoperative data, including patient questionnaires.
Main Results:
- 95% of patients reported no intraoperative pain.
- No patients required additional retrobulbar or peribulbar anesthesia.
- Common postoperative issues included pain, need for patching, and headache.
Conclusions:
- The combined TA and SCA technique is a safe and effective anesthesia option for cataract surgery.
- This method is medically acceptable and cost-effective.
- It reduces the need for more invasive anesthetic procedures.
