Introduction: Pterygium surgery is a closed globe surface surgery. Although it is perfectly standard and followed by excellent results, it is not exempt from the general rule that there is no surgery without risk. It therefore seems important to integrate simulation as a pedagogical tool for training ophthalmology residents in pterygium surgery.

Aim: To evaluate the effectiveness of procedural simulation as a training tool for pterygium surgery.

Methods: Eight residents participated in three simulation workshops.

Results: The global assessment of residents' knowledge showed a mean score of 3/5 [1.5/5-4/5] and 4.1/5 [3.25/5-5/5] before and after the training respectively. There was a significant negative correlation between the initial score on the pre-test and the improvement of this score on the post-test, with an r'=-0.87 and a p=0.005. We noted a significant improvement in the global performance score (p<0.001) and even a significant improvement in the specific performance score (p=0.02) between the 3 workshops. The average training satisfaction score was 13.87/16 [10/16-16/16]. We noted a significant positive correlation with r=0.838 and p=0.009 between knowledge improvement and learner satisfaction.

Conclusion: The training of fundus examination using an ophthalmoscopic simulator can improve the skills and knowledge of ophthalmic learners. This type of training can be an innovative addition to traditional learning methods.
