Summary
This study introduces a safer anesthesia technique for eye surgery, using topical anesthesia combined with a small lidocaine injection. This method avoids complications linked to traditional retrobulbar and peribulbar anesthesia, proving safe and effective in over 400 cases.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Retrobulbar and peribulbar anesthesia carry risks of serious complications during intraocular surgery.
- There is a need for safer anesthesia alternatives in anterior segment eye surgeries.
Purpose of the Study:
- To present a novel anesthesia method for anterior segment intraocular surgery.
- To demonstrate the safety and effectiveness of this alternative technique.
Main Methods:
- The technique involves topical anesthesia.
- A small volume (0.5 cc) of lidocaine with hyaluronidase and epinephrine is injected beneath the superior conjunctiva.
- This approach avoids retrobulbar or peribulbar injections.
Main Results:
- The described anesthesia method was successfully employed in 431 consecutive intraocular surgeries.
- The technique proved to be safe and effective, avoiding known complications of other methods.
Conclusions:
- This conjunctival injection anesthesia is a safe and effective alternative for anterior segment intraocular surgery.
- It offers a reduced-risk profile compared to retrobulbar and peribulbar anesthesia.
