An Inexpensive Practice Model for Microsurgical Skills Training: A Randomized Trial
In Brief
A clinical study evaluating Micro-stellated Icosahedron for Microsurgery. Completed, enrolled 27 participants across 1 site.
Detailed Summary
A single-center, prospective, randomized, controlled intervention trial to validate an inexpensive practice model for acquisition of microsurgical skills. Following a pre-assessment microsurgical skills task, participants were randomized to either an intervention group to build a micro-stellated icosahedron, or to a control group with no specific task assigned. A post-assessment microsurgical skills task was given to all participants after two weeks. Videos of pre- and post-assessments were masked and independently rated by two ophthalmologists using Video-based Modified Objective Structure Assessment of Technical Skill (OSATS) scoring criteria. Analyses were done to determine improvement in time required to complete tasks and in scores between pre- and post- assessments.

Timeline
Interventions
A portable, inexpensive microsurgery training model that requires the following materials for completion. a stereoscopic dissecting microscope, two jeweler style forceps, a pair of curved-tip micro scissors , 1 meter of monofilament nylon thread, 0.5 meter of polyimide microtubule material , one 15 cm metal ruler, a scalpel blade (#15), and double-sided tape. For a microsurgically-naive subject, a total of 20 hours are required to complete this model.
