An interventional study of infromedial single injection and medial canthus injection in Pain Due to Certain Specified Procedures, sponsored by Research Institute of Ophthalmology, Egypt. Status unknown at 2 sites in Egypt. Open to participants aged 16 Years to 70 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2022-09-21.

infromedial injection of 3 ml local anesthetic drugs and assessing the pain during lacrimal duct intubation and probability of false tracking
After entering the OR; the patient will be cannulated and fully monitored with basic monitors (pulse oximeter, NIBP \& ECG), a nasal cannula is connected to the patient to deliver oxygen.
We gave the patient 5 ml of propofol to decrease the discomfort felt by the patient during injection of local anesthesia. Benox eye drops is applied to the operative eye in both groups.
Patients were allocated into 2 groups; each group is 25 patients Group 1: We used a 25G/ 1" length needle to inject 3ml of lidocaine: bupivacaine (1:1) with 30 IU hyaluronic acid, 0.5ml below the inferior punctum in the lower lid medial margin.
Group 2: We used a 25G/ 1" length needle to inject 3ml of lidocaine: bupivacaine (1:1) with 30 IU hyaluronic acid classical medial canthal injection
During surgery, we will assess the pain degree during probing using Verbal Rating Scale (0 to 10 scale where 0 is no pain an 10 is unbearable pain), to assess the efficiency of this single low volume injection.
Research Institute of Ophthalmology, Egypt is the lead sponsor of 11 studies on the registry; 2 are open to participants now.
