Purpose
Corneal Foreign body and rust ring removal are essential ophthalmic skills, performed by nurse practitioners and ophthalmologists of all grades in the emergency setting.
We demonstrate and report an easily reprodicbile simulation model to practise corneal foreign body and rust ring removal.
Setting
Dry lab/hospital setting.
Methods
Initially we identified 6 expired Sabouraud dextrose agar plates from the emergency clinic.
4 plates were lightly dusted with iron filings (purchased from an online retailer) using an aseptic technique
2 of the plates were sprayed with a saline solution with a view to accelerate rust formation
2 of the plates were not sprayed with saline solution
2 additional plates were dusted using crushed 0.3mm pencil lead
The foreign bodies were lightly tamped onto the agar surface to embed them in the matrix
The iron filing plates were then incubated at room temperature for 48 hours.
Results
Students (undergraduate medical students and training grade ophthalmology registrars) were then surveyed on their confidence to remove corneal foreign bodies before and after a brief (10 minute) presentation on corneal foreign management and demonstrated simulation session.
The agar plates were mounted at a slit lamp and students were asked to remove the iron filings and graphite using a 30 gauge needle mounted on a 2.5 ml syringe.
Rust rings were removed using a Agar brush.
All students and registrars reported improved confidence following the simulation session.
Conclusions
This model is easily reproducible and at low cost using expired agar plates that would otherwise be disposed of.
All participants found the simulation improved their confidence following the simulation
Corneal foreign body simulation provides a safe environment to train foreign body and rust ring removal.
