Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
After excision of lower lid lesions, cases that can be repaired by a direct closure technique will be randomised to direct closure with suturing of the wound ( the standard treatment)by one of the ophthalmologists in the research team in an operating theatre, or laissez-faire ( left to heal by secondary intention). This is the intervention, and only occurs once. This will be carried out in an ophthalmology clinic. The patient not have any sutures inserted in to the eyelid defect. No dressing will be applied. The patient will be given instructions on self care of the wound - by performing wound care to clean the eyelid as necessary with supplied materials & saline solutions. The patient will apply antibiotic ointment to the wound for several days. All patients will be seen & assessed again within 4-5 days of their initial tumour excision. Any additional interventions that are required will be recorded by one of the investigators at the post-operative visits.
Intervention code [1] 317766 0
Treatment: Surgery
Comparator / control treatment
The control treatment is the direct closure technique of a lower lid wound. This will be suturing to close the wound by one of the ophthalmologists in the research team in an operating theatre.

The surgery is a one-off procedure & will be performed in an operating theatre or an appropriately equipped procedure room. It will performed under local anaesthetic alone or under sedation (if required, intravenous or oral). The wound will be cleaned and draped. Then the wound will be sutured closed by one of the investigators ( an oculoplastic surgeon or a supervised ophthalmic surgeon-in training) using a standard direct closure technique. The wound is closed in layers using dissolving sutures for the deep layers & skin sutures to close the skin. After surgery is completed, the eye is padded or left open depending on the risk of bleeding or ocular irritation. The patient will be seen buy one of the investigators within 4-5 days to assess the wound, remove the sutures and to note any additional interventions that are required.

Summary
Brief summary
Secondary intention healing, also known as laissez-faire, was first described in eyelid surgery in 1957. However, it is more common for surgical reconstruction to occur after skin lesion excision from the eyelids. There have been a few case series, advocating laissez-faire as a viable alternative treatment option with promising results that is not inferior to surgical reconstruction. The objective of this randomised control trial is to randomly assign cases that have had lower lid lesions removed to either Laissez-faire or surgical wound closure, and analyse the outcomes. We predict that there is no difference in outcome or at least no inferiority between Laissez-faire compared to primary direct closure.
