Educational Virtual Reality Simulators for Phacoemulsification Cataract Surgery
Phacoemulsification cataract surgery is one of the most common intraocular surgical procedures performed by ophthalmology residents, and may have complications such as posterior capsular rupture (PCR) and vitreous loss (VL). 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.
Atieh Pardazan Sharif (APZ Sharif) is a creative pioneer in design and reduction of advanced technologies and high-tech equipment in Iran. The company has been founded and directed by best educated people with high academic degrees who were experienced and professional in their field of work.
APZ Sharif owns advance laboratories and workshop facilities, and has done more than 40 projects in field of design and manufacturing of high technology parts and equipment, performance optimization and custom engineered solution.
SiMedix® is the first Product of APZ Sharif in Virtual Reality Simulation field. SiMedix® is a high-end virtual reality simulator for Phacoemulsification Cataract Surgery training.
To permit training of anterior segment surgery, the SiMedix® platform is equipped with a cataract eye interface, cataract instrument set, and foot pedals. Trainees see the intraocular surgical field through the operating microscope. The view is in stereo and offers realistic depth of field. Focus and zoom can be altered by using the microscope foot pedal. The instrument handpieces are inserted through incisions in the model eye. The cataract patient model head can be operated on from a temporal or superior position.
