Abstract
Background
To evaluate long-term daily activities after the implantable Collamer lens with a central hole (ICL-V4c) implantation for myopia throughout an 8-year follow-up.
Methods
The evaluation involved the follow-up of sixty eyes of 30 patients were over 8 years after ICL-V4c implantation. The analysis was focused on uncorrected (UDVA) and corrected distance visual acuities, vault, intraocular pressure (IOP), endothelial cell density (ECD), and vision-related daily activities.
Results
A total of 50 eyes (83.3%) had a postoperative UDVA of 20/20 or better. The central vault showed no significant difference from the observations at 3 months and 2 and 8 years (0.42 ± 0.3 and 0.42 ± 0.3 and 0.40 ± 0.2 mm, P = 0.06, P = 0.08, P = 0.08, respectively). The ECD decreased by 4.82% (P = 0.124), 4.58% (P = 0.065), and 4.43% (P = 0.057), respectively. The mean IOP remained stable over the 8-year follow-up (12.54 ± 1.53 and 12.9 ± 1.77 and 12.69 ± 1.64 mmHg, P = 0.02, P = 0.06, P = 0.07, respectively), The questionnaire scores indicated that at least 80% of the patients (24 patients) were highly satisfied and satisfied with their vision-related daily activities at 8 years after ICL-V4c implantation. A total of 6.7% of patients (2 patients) complained about difficulty driving at night at 8 years postoperation.
Conclusion
The outcomes of this study revealed the long-term viability and safety of the ICL-V4c implantation. The vision-related daily activities at 8 years after ICL-V4c implantation were highly satisfactory and satisfactory.
