Abstract
Purpose: To evaluate the postoperative vault, haptic position, and axis stability of vertical implantable collamer lens (ICL) implantation.
Setting: Fudan University Eye and ENT Hospital, Shanghai, China.
Design: Prospective.
Methods: This study included patients who underwent ICL implantation. Three months postoperatively, the vault, haptic position, and axis were measured.
Results: Ninety-eight eyes from 98 patients were included. At 3 months postoperatively, the vault was 517.10 ± 200.08 µm in the vertical group and 506.88 ± 204.19 µm in the horizontal group (P = .803). There was a significant difference in the distribution of haptics in the ciliary sulcus (ICS) between the two groups (P = .045). In the vertical group, an average of 0.90 ± 0.83 haptics near the incision and 1.33 ± 0.81 haptics away from the incision were located in the sulcus, showing a significant difference (P = .002). In those undergoing toric ICL implantation, 54% of eyes in the vertical group and 79% in the horizontal group experienced rotation, with a significant difference (P = .042). In the horizontal group, there were significant differences in both the vault and difference value between vertical and horizontal sulcus-to-sulcus (vSTS - hSTS) between the non-rotated and rotated subgroups (P = .019 and P = .035, respectively).
Conclusion: Customized vertical ICL implantation does not affect refractive outcomes and achieves an ideal vault. Situating the haptic near the incision in the ciliary sulcus is relatively more difficult for vertical implantation. Vertical implantation improves ICL stability in patients with a large vSTS - hSTS.
