Scientific titleSponge anaesthesia versus topical anaesthesia for subconjunctival antibiotics/steroid injections in Phacoemulsification + Implant Surgery Study
Study objectivesDoes the application of a pre-soaked oxybuprocaine swab on the conjunctiva reduce the pain of subconjunctival antibiotic/steroid injections more than topical oxybuprocaine alone?
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedSurgery: Anaesthesia
InterventionProspective randomised control study of patients undergoing phacoemulsification and implant under topical anaesthesia at Sandwell and West Birmingham NHS Trust and University Hospital NHS Trust. Informed consent to be obtained from the patient before the operation.

They will be randomised into two groups:
Group 1 will have a pre-soaked oxybuprocaine sponge placed in the inferior conjunctival fornix at the beginning of the procedure.
Group 2 will have a saline soaked sponge.
Both groups having routine topical anaesthesia for cataract surgery. The patient will be advised before the injection of the subconjunctival antibiotic injection. 1 ml of cefuroxime/betamethasone (this is a routine preparation done on the completion of cataract surgery) will be given into the inferior conjunctival fornix.

The pain assessment will be assessed immediately after the operation by the patient and an independent observer. This will be done with the 0-10 visual analogue scale. The surgeon will also fill in a separate form regarding surgical time. We will then analyse the two groups to determine if a pre-soaked sponge of oxybuprocaine gives more pain relief than a pre-soaked sponge with saline. Both arms of the study will receive a normal anaesthetic to reduce pain.
