“…Our results agree with those of previous studies on the use of ophthalmic surgery simulators (Sinclair et al 1995;O'Toole et al 1999;Voss et al 1999;Hikichi et al 2000;Berg et al 2001;Kaufmann 2001;Tsai et al 2001;Witzke et al 2001). Important and complicated steps in vitreoretinal surgery such as peeling of epiretinal membranes may be at least partially learnt by using a pars plana vitrectomy simulator where the training success and the surgical capacity of the test candidate can be assessed.…”

ABSTRACT.Purpose: To evaluate whether microsurgical steps in vitreoretinal surgery can be taught by a computer-assisted training system. Methods: This prospective, randomized experimental study included 14 ophthalmic residents and medical students who were completely inexperienced in microsurgery. They were randomized into two groups. The study group underwent training programmes in a computer-assisted training system for simulation of pars plana vitrectomy. The control group did not participate in any in vitro training. In the second phase of the study, participants of both groups performed a pars plana vitrectomy in three pig eyes, which included picking a metallic foreign body from the retinal surface. Results: The amount of retinal detachment and the number of retinal defects at the end of the vitrectomies were smaller, the time needed to remove the foreign body was shorter, the number of retinal lesions associated with the foreign body removal was lower, and the mark given was better in the trained study group than in the untrained group. The relatively small number of study participants did not allow the differences between the study and control groups to reach the 5% level of error probability. Conclusions: In an animal model, training by a computer-based medical work station for simulation of pars plana vitrectomy showed better outcome measures for trained study participants compared with untrained study participants. Future studies may show whether further refinements of such training programmes will result in statistically significantly better results in surgical outcome parameters.

“…Advances in computer technology have prepared the ground for new and innovative teaching strategies in the form of increasingly sophisticated virtual reality (VR) training simulators which allow for high-fidelity operation simulations. VR surgery simulators have been developed for retrobulbar injection [11], capsulorhexis [23,24], phacoemulsification [8,19], retinal photocoagulation [15] and vitreoretinal surgery [5,16,22]. Skill acquisition has been demonstrated for a retinal photocoagulation simulator [12].…”

“…Hikichi et al have recently reported a similar simulator for vitreous surgery but technical details are lacking in the paper. 14 We are also aware of a commercial development of a virtual reality simulator by a German company, but this has not been the subject of a research paper. Collaborative efforts are now under way between our groups to develop the system further so as to provide a 'near live' experience of vitreoretinal surgery to the trainees.…”

Aim To develop computer simulation of steps in vitreoretinal surgery using virtual reality technology. Material and methods A workstation with three-dimensional position tracking stylus was attached to a Pentium II desktop PC with a graphic accelerator. Computer algorithms were developed using Open GL and Microsoft Visual C þ þ languages to control the interaction and update the visual feedback tracking the instruments. Soft tissue computer modelling was carried out to mimic the removal of a vitreous opacity. Lens touch with the instruments was also detected. Mathematical modelling to allow for lens distortion was taken into account. Results A virtual reality computer model has been developed that can simulate initial steps of vitreoretinal surgery. Soft tissue modelling of the vitreous opacity and its removal by the vitrector was successfully simulated. The movements of the active and passive instruments in the dummy eye corresponded to the movements on the computer screen. On evaluation of the system, there was a minimal but discernable time lag between the stylus movement and the visual feedback. There was no tactile feedback when the lens touch was simulated. No further complex vitreoretinal surgery simulation was possible at this stage.
