How to remove a lavage system which has “grown in “?
- Palpate the sub-conjunctival foot plate to locate it.
- Inject subconjunctival local anaesthetic over the foot plate after first anaesthetising this site with a topical local soaked sterile cotton bud.
- Inject local anaesthetic around the exit point of the lavage tube taking care not to lacerate the tube with the needle.
- Cannulate the short cut end of the lavage tube using the blunt ended cannula supplied with the kit.
- Prolapse the third eye lid to protect the cornea prior to attempting to push the foot plate against its conjunctival covering.
- In many cases the buried foot plate can be visualised and a small conjunctival incision made using the tip of a guarded 18g needle or small conjunctival scissors to allow removal.
- Blind dissection can be performed with care using an 18g needle guarded by a gloved finger.
- Should conjunctival dissection not be possible a small cutaneous incision can be made adjacent to the tubes exit point to facilitate removal.
- Systemic antibiotics and NSAIDs should be given if surgical removal is required.
