Trial 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).

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • patients undergoing bilateral oculoplastic procedures under local anaesthesia on selected lists at Southampton General Hospital or Lymington New Forest Hospital, UK
  • able to give informed consent and adhere to the study protocol

Who cannot join

  • patients undergoing substantially different procedures on each eye
  • patients undergoing procedures not amenable to the administration of anaesthetic via the transconjunctival route (e.g. brow lift)
  • patients undergoing a first procedure on one eye and a 'redo' procedure on the fellow eye (as the presence of scar tissue on the previously operated eye is likely to affect results)
  • patients having their procedure under general anaesthesia, or receiving intravenous sedation prior to the administration of local anaesthetic

About this study

Official title: Comparative Study of Transconjunctival vs. Transcutaneous Routes for Administration of Local Anaesthesia in Oculoplastic Surgery

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Topical AnestheticDrug

    Topical anaesthetic drops (proxymetacaine 0.5% and tetracaine 1%) applied

  • Transconjunctival anaestheticProcedure or surgery

    Local anaesthetic (50/50 mixture of bupivacaine 0.5% / lidocaine 2% with adrenaline 1:200 000) administered to the eyelid via the transconjunctival route

  • Transcutaneous anaestheticProcedure or surgery

    Local anaesthetic (50/50 mixture of bupivacaine 0.5% / lidocaine 2% with adrenaline 1:200 000) administered to the eyelid via the transcutaneous route

  • Patient comfort questionnaireOther

    The patient will be asked to rate the level of pain during each local anaesthetic injection on a 0-10 scale

  • Facial photographOther

    The patient will have a photograph taken following the anaesthetic injections to document the presence or absence of bruising

  • Eyelid surgeryProcedure or surgery

    Eyelid surgery will be performed as per the plan from their preoperative appointment

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain during local anaesthetic administration

    Patient-rated pain intensity during administration of local anaesthetic via each route (transconjunctival and transcutaneous), expressed on a 0-10 scale (0 being no pain at all and 10 being the worst pain possible)

    Measured: During local anaesthetic administration (2-3 minutes)

Secondary outcomes (3)
  1. Requirement for additional anaesthetic

    Requirement (or lack thereof) for additional 'top up' anaesthetic during the eyelid surgery.

    Measured: During surgical procedure (up to 1 hour)

  2. Bruising after local anaesthetic

    Amount of bruising visible on facial photographs taken after the anaesthetic is administered but before the eyelid surgery, rated on a numeric scale of 0-3 by an independent assessor (i.e. a member of the research team who did not perform the anaesthetic or surgery).

    Measured: Immediately after local anaesthetic (2-5 minutes)

  3. Other complications

    Occurrence of any other complications or adverse events potentially attributable to the administration of local anaesthesia

    Measured: During anaesthetic administration, surgery, or up until the first postoperative visit (2-3 weeks later)

Questions about this trial

What is this clinical trial studying?

A study testing Topical Anesthetic, Transconjunctival anaesthetic and Transcutaneous anaesthetic in people with Anesthesia, Local and Eyelid Diseases, run by University Hospital Southampton NHS Foundation Trust at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 25 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact We Fong Siah (0044 23 8120 4761, we.siah@uhs.nhs.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain during local anaesthetic administration (time frame: During local anaesthetic administration (2-3 minutes)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04102878, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
