Over the past few decades, simulation-based training has become an increasingly widespread learning tool for training in medical procedures. This type of training provides the opportunity to learn in a safe simulation-based environment, where both technical and diagnostic skills can be developed. In Denmark, there has been developed evidence for simulation-based training in ophthalmology in cataract and vitreoretinal surgery. This form of evidence-based training is meaningful for real clinical setting, and in this review, we argue, that is important to apply for all medical fields.
