“…Their third model made use of a glass sphere and wax to simulate the eyeball, and melted crayon was used as the corneal FB. Their final model was an agar plate simulating the eye, with peppercorn as corneal FBs [1]. More recently in 2017, a task-trainer using ballistics gel, silicone, paint thinner, baby oil, petroleum jelly and cornstarch was created for under USD$75.…”

“…Having looked at all the available literature at making a Fig. 2 Participants' questionnaire responses using the 7-point Likert Scale simulation eye model, we feel that our low-cost, lowtech model has an advantage over the others, for the following reasons: [1] our model approximates the consistency of a human cornea well, [2] its hemispherical shape simulates that of the eye ball and allows users to appreciate depth of the corneal FBs, and [3] it is quick, easy, and cheap (under USD$1) to re-create and particularly suited for an environment with tight resources.…”

“…Patients with a corneal foreign body (FB) form an important group of people presenting to the Emergency Department (ED) with ocular complaints [1,2]. This makes it important for doctors working in the ED to be familiar with the procedure of corneal FB removal.…”

Background: Patients commonly present to the Emergency Department with a corneal foreign body (FB). There is currently a lack of adequate training for junior doctors in the management of this condition. Our self-made surrogate eye model aims to address this void in our junior doctors' knowledge.Methods: Participants were guided through a hands-on session with a slit-lamp using our eye model, which is made of a hemispherical agar embedded with pencil lead fragments simulating as FBs. Using a 7-point Likert scale, all participants completed a questionnaire both before and after training, for: (1) knowledge in corneal FB removal, (2) confidence in corneal FB removal, and (3) effectiveness of the model. Results: Out of 73 participants, 82.2% (60/73) had no prior experience in corneal FBs removal. After the training session, their knowledge improved from a median score of 2 (interquartile range [IQR] 1 to 3) to 5 (IQR 5 to 6), with improvement in confidence levels from 2 (IQR 1 to 2) to 5 (IQR 4 to 6). The effectiveness of our eye model scored a median of 6 (IQR 5 to 7).Conclusions: Our surrogate eye model is low-cost, quick and easy to reproduce. After use, our learners expressed greater confidence in managing the removal of corneal FBs and use of slit lamp. With a recent focus in patient safety and quality, teaching this procedure via simulation is a safe way of bridging the gap between traditional didactic teaching and the clinical environment.

“…This was following a local survey which indicated that 72% of practitioners would have preferred to practise on a simulator before working with patients. The study proposed the use of a low-tech model made out of a cardboard box and ink to practise the use of slit lamp and procedural skills for corneal foreign body removal (Gallagher et al 2016). Similarly, various inanimate models have proven to be useful for the training of laser procedures, including iridotomy (no.…”
