Bupivacaine vs Oxybuprocaine Topical Anesthesia in IVI

A Double Blinded Randomized Controlled Study of Topical Anaesthetics Oxybuprocaine Versus Bupivacaine 0.5% in Intravitreal Injections

comparing two local anaesthetic agents, Bupivacaine 0.5% versus Oxybuprocaine used topically to provide surface anaesthesia before IVI procedures.

In preparation zone, we will cannulate the patients, connect them to the pulse oximetry and we will start providing appropriate surface anaesthesia for an adequate period of time before the patient administration of the injection, by applying the anaesthetic agents, 3 times with 5 minutes interval, for 15 minutes and then waitng the injection

All patients are informed that they are going to receive topical anaesthetic agent before the IVI.

pain is monitored during the injection by using the 11 points verbal numerical pain scaling as zero is for no pain and 10 is for severe unbearable pain.

Inclusion Criteria:

• All patients between 30 to 70 years

Exclusion Criteria:

• uncooperative patients
