What type of anesthetic is typically used for minor procedures?

Local anesthetics are specifically designed to block sensation in a targeted area of the body, making them ideal for minor procedures. They work by interrupting the nerve signals in the area where they are applied, allowing the procedure to be performed without the patient feeling pain. This type of anesthetic helps maintain patient comfort while minimizing the risks and complications associated with deeper anesthesia methods.

Local anesthetics are commonly used for various minor ophthalmic procedures, such as cataract surgery, punctal occlusion, or the removal of surface lesions. They allow patients to remain conscious and cooperative during the procedure, which can be advantageous for both the ophthalmic technician and the patient.

In contrast, systemic anesthetics affect the entire body and are not typically utilized for minor, localized procedures where only a small area requires anesthesia. General anesthesia induces a controlled state of unconsciousness and is more suited for extensive surgeries requiring complete insensitivity to pain and awareness. Therefore, local anesthetics are the preferred choice for minor procedures due to their efficacy and safety profile.
