Summary
Eyelid surgery is commonly performed under local anaesthesia. For many such procedures, the
local anaesthetic injection may be given either transcutaneously (through the skin) or
transconjunctivally (through the conjunctiva, i.e. from the inner surface of the eyelid after
administration of topical anaesthetic drops). Both methods are commonly used, sometimes in
combination. Currently, the choice of route is largely determined by surgeon preference, but
it is not known whether one method is better or more comfortable than the other. Our study
will compare the two methods of local anaesthetic administration, in terms of patient comfort
during anaesthetic administration, efficacy (i.e. whether any additional anaesthetic is
needed during surgery), and adverse effects (e.g. bruising, postoperative double vision).
We will recruit adult patients who are due to undergo eyelid surgery on both sides under
local anaesthesia, on Miss Siah's lists at Southampton General Hospital or Lymington
Hospital. Patients will receive topical anaesthetic eye drops to both eyes, followed by an
injection of local anaesthetic to each eyelid. One side will be administered
transcutaneously, and the other side transconjunctivally. The order be randomised. After the
injections, participants will be asked to rate their pain levels during each injection on a
standardised numerical scale (1-10). A photograph will also be taken, so that an independent
assessor can subsequently rate the extent of any bruising. The eyelid surgery will then be
performed as normal, with any need for further anaesthetic during the surgery being recorded.
Patients will attend for their normal follow-up appointment afterwards and any postoperative
complications will be recorded, but the study will not require any extra hospital visits. The
study is sponsored by University Hospitals NHS Foundation Trust, but does not have any
external funding.
