Long-Term Assessment of the Quality of Visually-Related Daily Activities After ICL (V4c) Implantation for Myopia and Myopic Astigmatism

Abstract

This study was performed to evaluate the long-term quality of visually related daily activities after Central Hole Collamer Lens Implantation to treat myopia and astigmatism. This study included 46 eyes (in 23 patients) that received ICL-V4c implantation. The follow up time was at least 24 months. Moreover, patient satisfaction related to daily vision activities were recorded at 6 and 24 months. The parameters measured included uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction, eye axis, intraocular pressure (IOP), endothelial cell density (ECD) and vault. The mean spherical equivalents were –0.14 ± 0.21 D and –0.12 ± 0.33 D at 6 and 24 months after surgery, respectively. All the eyes were better postoperative (UCVA) than preoperative (BCVA). The BCVA at 6 and 24 months after implantation was –0.03 ± 0.08 LogMAR and –0.03 ± 0.11 LogMAR, which is statistically better (P = 0.031) than the pre-operation value 0.07 ± 0.12 LogMAR. There was no significant (P > 0.05) difference between the pre-operation and post-operation ECD. At 24 months post-operation, 10% of the patients complained about difficulty driving at night; meanwhile, most patients expressed satisfaction or were very satisfied. Approximately 13% of the patients worried about long term safety and efficacy after the ICL-V4c implantation. Patients are very satisfied with daily related vision activities after ICL-V4c implantation.
