Summary
The "drop, then decide" topical anesthesia approach successfully enabled 89.3% of patients to avoid regional blocks for anterior segment surgery. This method increases patient eligibility for topical anesthesia benefits.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Topical anesthesia offers advantages for anterior segment surgery but patient selection can be challenging.
- Traditional methods may exclude patients who could otherwise benefit.
Purpose of the Study:
- To evaluate the efficacy of a "drop, then decide" approach to topical anesthesia.
- To determine the success rate of topical anesthesia for various anterior segment surgeries without preselection.
Main Methods:
- A consecutive series of 150 anterior segment surgeries were performed.
- All cases began with topical anesthesia and intravenous sedation.
- Anesthetic blocks were administered only if necessary based on patient response.
Main Results:
- The overall success rate (no regional block required) was 89.3%.
- For cataract extraction with intraocular lens (IOL) implantation, the success rate was 92.0%.
- High success rates were observed even in patients typically considered poor candidates, though younger patients experienced more difficulty.
Conclusions:
- The "drop, then decide" strategy effectively expands the use of topical anesthesia for anterior segment procedures.
- This approach enhances patient comfort and allows more individuals to receive the benefits of topical anesthesia.
