Application of glasses-free 3D in Implantable Collamer Lens (ICL) surgery training

Abstract Object: To discuss the application and effect evaluation of glasses-free 3D technology in ICL surgery teaching. Methods: 10 ophthalmologists with no experience in (implantable collamer lens) ICL surgery were selected to randomly watch the videos of 10 cases of ICL surgery on a 2D traditional screen and 10 cases on a glasses-free 3D screen, respectively, and complete the questionnaire on the learning experience after watching. The learning experience includes the incision making process, anterior chamber changes during viscoelastic injection and removal, the lens position judgment after the injection, the adjustment of the lens loop process, the overall three-dimensionality of the surgery, and the situation of dizziness. Results: The glasses-free 3D group showed better learning experience (P<0.05) in the incision making process, the changes of the anterior chamber during viscoelastic injection and removal, the adjustment of the lens loop, and the stereoscopic effect of the surgical video. During the lens injection process, the glasses-free 3D group could more accurately determine the initial position of the foot loop (P<0.001). There was no significant difference in the accuracy between the two groups (P=0.317) on the question of whether the ICL is turned over. Compared with the traditional 2D group, the glasses-free 3D group was more likely to experience dizziness (P<0.001) Conclusions: The glasses-free 3D display videos are more conducive for ophthalmologists to learn the key steps of ICL surgery, but it is still prone to dizziness.
