ABSTRACT
Objective
To describe and validate an ophthalmic model for corneal transplantation and micro suture training using a bovine eyeball as a model.
Methods
For the training model, the eyeball was placed under the sanitary field placed on the ends of a common 3.5cm diameter cylindrical plastic container for corneal removal. A superficial circular incision was made, then 9cm curved Castroviejo scissors were used for complete corneal removal. The cornea was replaced in its original position, and 10-0 nylon thread was used to perform the sutures, with 9 equidistant stitches. Finally, the following criteria were evaluated: suturing time, time and quality progression in each attempt, dexterity and suturing improvement.
Results
The described model proved to be feasible and suitable for corneal micro suture training, allowing improvement and gain of dexterity in the sport.
Conclusion
The presented microsurgical training model has a high feasibility for the simulation of ophthalmic surgeries, in addition to a texture similar to the real human eye, which makes it close to reality.
