| Outline of Final Research Achievements |
It was possible to optimize the size of Hole ICL by directly measuring the sulcus-to-sulcus diameter with swept source optical coherence tomography. There were no significant differences in the induction of higher-order aberrations, contrast sensitivity function, subjective and objective forward scattering, modulation transfer function, or glare and halo. Visual performance after Hole ICL implantation was superior to that after LASIK. A slight edge glare was detected by photography from the model of the Hole ICL-implanted eye, and it was prominent when dislocated or tilted. The speed of the aqueous flow was higher after Hole ICL implantation than that after conventional ICL implantation. Hole ICL implantation was safe and effective, and provided predictable and stable results, during the long-term follow-up period. The rates of cataract formation and the intraocular pressure rise were significantly lower after Hole ICL implantation than that after conventional ICL implantation.
