Construct validity of anterior segment anti-tremor and forceps surgical simulator training modules

Abstract

The EYESi surgical simulator anterior segment forceps and anti-tremor modules showed significant (P< .05) construct validity.

The development of a virtual reality training programme for ophthalmology: repeatability and reproducibility (part of the International Forum for Ophthalmic Simulation Studies)

“…However, the internal numerical variance and its statistical significance have not been analysed in detail before and this is relevant for the trainers, the individual trainees but also for the design of a training syllabus. Construct validation on the simulator has been established comparing novice groups with a more senior surgical cohort [12][13][14] and on average the more experienced performed better. All trainees enroled in this study had previously passed through a competitive selection process and were now in their first year of the London Deanery School of Ophthalmology Programme.…”

“…The ability to differentiate between different levels of expertise (construct validity) has been demonstrated for the capsulorhexis, cracking and chopping, navigation, and anti-tremor modules. [12][13][14] The capsulorhexis involves the following steps: injection of viscoelastic into the anterior chamber, flap creation, and capsulorhexis formation. For the cracking and chopping, the trainee is required to pull two spheres simultaneously until they reach a given length illustrated by a change in colour.…”

“…6,9 However, no specific analysis was ever undertaken with regard to the repeatability, reproducibility, or variability among novice trainees but rather these subjects were compared with more senior colleagues. 5,6,[8][9][10][11][12][13][14][15] What we therefore do not know is how an individual with minimal experience scores when undertaking the same task on several occasions (variability and reproducibility).…”

Virtual reality cataract surgery training: learning curves and concurrent validity

“…The VR simulator provides metrics and scoring at the end of each performed task. These scores correlate with the experience of intraocular surgery indicating construct validity (Rossi et al 2004;Mahr & Hodge 2008;Solverson et al 2009) and VR training can improve capsulorhexis wet-laboratory performance (Feudner et al 2009). Posterior segment VR training has been investigated but little is known regarding the learning curves associated with training on the simulator's anterior segment modules as well as the validity of the simulator's scoring system.…”

Simulador cirúrgico e realidade virtual no ensino de cirurgia de catarata

“…Sua aplicação como método de ensino para facoemulsificação inclui as etapas de capsulorrexe, hidrodissecção e delineação, emulsificação do núcleo e aspiração do córtex e já foi documentado e validado (7)(8)(9)(10)(11) . O treinamento prático com simuladores cirúrgicos (que vem sendo denominado "Dry-lab", em oposição ao tradicional "Wet-lab", onde são utilizados olhos de animais para o treinamento ex-perimental) já é realidade no Brasil.…”
