Description and validation of a structured simulation curriculum for strabismus surgery

Abstract

Purpose: To describe and validate a Web-based structured simulation curriculum of strabismus surgery for residents in training using noncadaveric eye models.

Methods: A pre- and posttest of cognitive skills, objective wet laboratory structured assessment of technique, and summative global evaluation form were implemented as part of a systematic ophthalmology wet lab (OWL) curriculum. Strabismus techniques were taught using a structured simulation method on noncadaveric models of eyes. Likert scale questionnaires were administered to assess the comfort level with strabismus surgery of residents before and after participation in the wet laboratory. Statistical analysis was performed using the paired t test.

Results: Seven residents participated in the curriculum. Average test scores improved from 65% to 91% (P = 0.0002). Resident comfort level improved from an average score (assessed by Likert scale of 1-5) with standard deviation of 2.6 ± 1.0 to 4.3 ± 0.5 for passing scleral sutures (P = 0.0008), of 2.6 ± 0.5 to 4.3 ± 0.5 for isolating and suturing muscles (P = 0.00004), and of 2.7 ± 1.0 to 4.6 ± 0.5 for comfort with naming instruments (P = 0.0007).

Conclusions: In this study of 7 residents, knowledge and comfort level with strabismus surgery statistically improved with a structured simulation curriculum.
