Computer Simulation for Cataract Surgery


A computer simulation tool that provides a more effective way of teaching physicians the art of cataract surgeries has been revealed in this month’s edition of Ophthalmology. Compared to the traditional teaching methods, this computer simulation appears to provide more efficient training for doctors and with cataract surgery being one of the most in-demand eye surgeries, it is important for doctors to master its difficult procedure.

The Massachusetts Eye and Ear Infirmary Cataract Surgery Trainer gives a kind of simulation of what a cataract surgery is like. The viewer sees what decisions, tasks and skills are needed in order to perform a successful cataract surgery. Unlike traditional methods, the trainee is fully involved in this simulation as they are asked to decide what actions they would take. Once their action has been decided the computer screen will show an animated vision of how their action transpires in surgery before they are given feedback. Thus, if the trainee chooses the wrong type of action, they will learn from their mistake and can then go on to read further information in this area. The programme is designed to be specific to each individual, as some areas may be more uncertain for some than others. This is why the programme has been designed to allow the viewer to see various visual demonstrations; listen to commentaries made by surgeons, professors and so on, all in the hope of enhancing their surgeries.

The effectiveness of The Massachusetts Eye and Ear Infirmary Cataract Surgery Trainer was tested by splitting a group of trainees into two groups; one of which had traditional teaching methods with written lessons, the other received the Cataract Surgery Trainer CD alongside the traditional teaching methods. Of the two groups there was no difference between pretest scores but a significant difference in posttest scores with the group who had access to the Cataract Surgery Trainer simulation coming significantly out on top. Overall, the key to this simulation tool appears to lie in the fact that it allows patients to almost experience surgery and see the consequences of their actions. With its success rate already looking to over-take traditional teaching methods; perhaps the simulation teaching process will be introduced into other complicated surgeries.
