Pain control and subconjunctival haemorrhage after intravitreal injection using cooled anaesthetic eyedrops and antiseptics: A prospective, double-blind, randomized controlled trial.

The benefit of using cooled anaesthetic eyedrops and antiseptics to alleviate pain and minimise subconjunctival haemorrhage following intravitreal injection was not proven in the general population. It may be beneficial in part for some patients, such as those who regularly use eyedrops, patients with hypertension or those not on antithrombotic therapy.
