The application of three-dimensional printing technology of MRI in posterior sclera reinforcement surgery for high myopia

Abstract

Objective To investigate the application value of three-dimensional (3D) printing technology of MRI in posterior sclera reinforcement surgery for high myopia. Methods The data of 29 eyes of 30 patients with high myopia were collected and they underwent posterior sclera reinforcement ( PSR ). All cases received 3D MRI before and after PSR. The MRI data of patients were reconstructed by using materialise’s interactive medical image control system software to generate stereo lithography ( STL ) file, then STL file was turned into print recognizable path file by printing program software, and finally 3D eyeball, ocular muscles, optic nerve and PSR strip model were printed proportionally by using 3D printers. Results According to MRI image data, 3D solid individualized proportional model of eyeball, ocular muscles, optic nerve and PSR strip were successfully printed. Conclusion Three-dimensional proportional model of eyeball, ocular muscles, optic nerve and PSR strip made by 3D printers are contribute to preoperative and postoperative PSR with the certain value in application.
