Phacoemulsification training is one of the fundamental parts of the residency program curriculum and needs to ensure improved visual outcome in patients.

In advanced countries, the apprenticeship model was used for more than 100 years to train and evaluate residency skills through direct supervision and feedback. This Training were carried out at the Wet-labs with enucleated animal eyes.

In the 1990's, the emergence of virtual reality (VR) knowledge & computer simulation led to a revolution in the way of cataract surgery training. Germany and the United States manufactured educational cataract surgery simulator based on High technology.

Today, Iran (as the third country) has succeeded in producing this product, cheaper and with special competitive advantages. APZ Sharif Co is the Iranian company that has been able to produce this product with ‘SiMedix®’ brand.
