Outcome Measures
Primary Outcomes (2)
Pain on Injection
Pain on a scale of 0-10 during injection process (0 being no pain, 10 being worst pain ever experienced). These will be patient-reported verbally and recorded immediately after injection.

Bacteriostatic Saline as Local Anesthesia
EXPERIMENTALPatients receiving bacteriostatic saline as local anesthesia for in-office minor eyelid procedures at University of California, San Francisco Medical Center, Oculoplastics department
Lidocaine with Epinephrine as Local Anesthesia
ACTIVE COMPARATORPatients receiving lidocaine with epinephrine as local anesthesia for in-office minor eyelid procedures at University of California, San Francisco Medical Center, Oculoplastics department
Interventions
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.
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.
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.
