Bacteriostatic Saline as Local Anesthesia
Patients receiving bacteriostatic saline as local anesthesia for in-office minor eyelid procedures at University of California, San Francisco Medical Center, Oculoplastics department
0.9% Bacteriostatic Local Anesthetic Injection
Following research and procedural consent, local anesthetic injection will be carried out using a standard 1 cc of local anesthetic corresponding to the study arm (0.9% bacteriostatic saline or 1% lidocaine with 1:100,000 epinephrine). Prior to anesthetic administration, the procedure site will be cleaned using standard measures. A 30 gauge needle on a 3 centimeter cubed volume syringe will be utilized. Five minutes will be given for local anesthetic to take effect.
Eyelid Lesion Removal
Following anesthesia administration, patient will proceed with recommended eyelid lesion removal. The procedure site will be cleaned according to standard protocol, and standard technique for lesion removal will be performed, which will vary according to type of lesion but may involve use of Westcott scissors, forceps, #15 or #11 blades or other oculoplastics administration. The exact procedural details will be at the discretion of the surgeon.
Lidocaine with Epinephrine as Local Anesthesia
Patients receiving lidocaine with epinephrine as local anesthesia for in-office minor eyelid procedures at University of California, San Francisco Medical Center, Oculoplastics department
1% Lidocaine with 1:100,000 epinephrine Local Anesthetic Injection
Following research and procedural consent, local anesthetic injection will be carried out using a standard 1 cc of local anesthetic consisting of a commercially available mixture of 1% lidocaine with 1:100,000 epinephrine. Prior to anesthetic administration, the procedure site will be cleaned using standard measures. A 30 gauge needle on a 3 centimeter cubed volume syringe will be utilized. Five minutes will be given for local anesthetic to take effect.
