Comparison of Three Different Anesthetic Approaches for Intravitreal Injections

The patients in the group Drops received a drop of proparacaine 0.5% before receiving a peri-ocular drop of povidone iodide 5%. The patients in the group Drops received a second drop of proparacaine 0.5% 5 minutes after the drop of povidone iodide 5%

The patients in the group SC received a drop of proparacaine 0.5% before receiving a peri-ocular drop of povidone iodide 5%. In the patients in the group SC, a subconjunctival bleb of anesthesia was created by injecting 0,4 mL of lidocaine 1% into the subconjunctival space 4 mm posterior to the superotemporal limbus with a 30-gauge, 1/2-inch needle attached to a 1-mL syringe.

For the patients in group gel, the gel was placed on the eye before receiving the peri-ocular drop of povidone iodide 5%.
