ABSTRACT
PURPOSE: To compare the postoperative endothelial cell counts of EVO-ICLs with a central hole (V4c and V5) and laser vision correction surgery (LASIK or PRK).
SETTING: OOO Eye Center, OOO, South Korea.
DESIGN: Retrospective, observational, and paired contralateral study.
METHODS: We retrospectively reviewed 62 eyes of 31 patients who underwent EVO-ICL with a central hole implantation in one eye (pIOL group) and laser vision correction in the contralateral eye (LVC group) to correct refractive errors. Central endothelial cell density (ECD), percentage of hexagonal cells (HEX), coefficient of variation in cell size (CV), and adverse events were evaluated for at least three years. The endothelial cells were observed using a non-contact specular microscope.
RESULTS: All surgeries were performed, without complications during the follow-up period. The mean ECD loss values compared with the preoperative measurements were 6.65% and 4.95% during the 3 years after pIOL and LVC, respectively. There was no significant difference in ECD loss compared to the preoperative values (paired t-test, P = 0.188) between the two groups. No significant loss in ECD was observed at any time point. The pIOL group showed higher HEX (P = 0.018) and lower CV (P = 0.006) values than the LVC group at the last visit.
CONCLUSION: According to our experience, EVO-ICL with a central hole implantation was a safe and stable vision correction method. Moreover, it did not induce statistically significant changes in ECD 3 years postoperatively compared with LVC. However, further long-term follow-up studies are required to confirm these results.
