New eye model for teaching strabismus surgery at McMaster University


Dr. Kourosh Sabri from McMaster University is leading a group of biomedical engineers to develop a new eye model for teaching strabismus surgery.


Teaching ocular microsurgery is a complex process with many competing factors: patient safety, quality of surgery, and the need to train our future surgeons. Most existing eye models for instruction focus on cataract surgery. Furthermore, with the transition from large incision cataract surgery to small incision phacoemulsification, ophthalmic trainees rarely perform suturing during cataract surgery and therefore do not practice suturing as much as before. Developing a purposely designed model for strabismus surgery would allow trainee surgeons to hone their skills in a safe, life-like environment before starting to operate on real patients.


Dr. Sabri is leading a group of biomedical engineers to develop a new eye model for teaching strabismus surgery. This new teaching model will include artificial material that mimics the texture of extraocular muscles and their actual dimensions. Special attention will be paid to the actual placement of the extraocular muscles on the globe as well as the position of the forehead, nose, and orbital rims to simulate challenges a surgeon faces with the placement of their hands during strabismus surgery. Creating as life-like a model as possible will give our future surgeons the best training possible before they embark on strabismus surgery on live patients.
