He X, Niu L, Miao H, et al. - Researchers conducted this observational study to assess the relative position of the central hole (C_H) of EVO Implantable Collamer Lens (EVO-ICL), the pupil center (C_P), and the corneal center (C_C) after implantation of EVO-ICLs for moderate to high myopia. This investigation was carried out on patients who had EVO-ICL implantation from January 2016 to October 2016 in the Department of Eye & ENT Hospital of Fudan University. Eighty-nine eyes of 47 patients with moderate to high myopia have been assessed. All surgeries have been conducted safely, and no complications were noted in follow-ups 4.3 ± 4.82 months after surgery. An imperfect match between the central hole of EVO-ICLs and the pupil center does not necessarily show ICL dislocation. The position of the central hole of EVO-ICL is closer to the corneal center compared with the pupil center.
