“…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. This task-trainer also included the use of a Styrofoam mannequin head and reported a time of approximately 90 min to complete [15]. There have even been literature describing the use of bovine eyes as a way to teach this procedure [16].…”

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.

“…10,[12][13][14]16 Though these are possible CFBs, metal grinds as CFBs would be more realistic given these are common industrial injuries. 17 The metal grind CFBs have been described in a previous eye simulation, 18 but in that simulation, the corneas were made from silicone and cornstarch. Not only are these models unrealistic, but it would be a challenge to place these models in a Slit-lamp or obtain a realistic experience when using the Woods lamp or iCare Tonometer.…”

“…In addition, several eye SIM curricula have been described in the education literature. [10][11][12][13][14][15][16][17] These curricula have not focused on specific instruction in the use of the iCareTonometer, the Woods Lamp, the Slit Lamp, and the ophthalmologic burr/hollow bore needle for CFB removal. Of the CFB removal curricula, the prior course designs have lacked realism due to the unnatural artificial eye models (agar trays, gel, glass spheres, cardboard) [10][11][12][13][14] and the uncommon CFBs (wax, ground pepper, peppercorn, mustard seeds).…”

Purpose: This simulation curriculum is structured to teach the use of common eye assessment equipment and corneal foreign removal techniques using harvested cow eye models, the ophthalmologic burr, and the hollow-bore needle. Methods: This curriculum involves using one self-assessment (SA) station and three skills stations. The skill stations teach the use of the iCareTonometer, Woods Lamp, and Slit Lamp, and train corneal foreign body removal using a burr and hollow-bore needle. Results: Sixteen first, second, and third-year (PGY 1-3) residents of the University of Alabama at Birmingham (UAB) Emergency Medicine participated. 100% indicated this should be an annual training with 87% indicating this was highly realistic. There was a 44% Pre-Sim to 94% Post-Sim SA for improvement with iCareTonometer skill. There was a 7% Pre-Sim to 100% post-Sim SA for improvement with Slit-Lamp skill. There was a 32% Pre-Sim to 100% Post-Sim SA improvement with Woods Lamp skill. For CFB removal, there was a 13% Pre-Sim to 94% Post-Sim SA for improvement with burr and hollow-bore needle skill. Conclusion: The self-assessments indicated that this simulation was successful in leading these emergency medicine residents to attaining enhanced self-assessed competencies in the use of common eye assessment equipment and for corneal foreign body removal using the burr and the hollow-bore needle. To establish curriculum globalization, reliability, and competency, larger test groups will have to be studied and objective qualified testers will need to assess competencies.
