ABSTRACT

PURPOSE:

To evaluate the vault change after implantable collamer lens (ICL) size exchange according to the preoperative vault.

METHODS:

In 14 eyes of 13 patients, the vault change after ICL exchange operation due to unideal vault was compared in 2 groups, the smaller ICL exchanged group and larger ICL exchanged group.

RESULTS:

In 6 out of 14 eyes, the ICL was exchanged to a 0.5 mm smaller size and the vault was changed from 1.38 mm (1.18-1.70) to 0.71 mm (0.51-0.92) (p = 0.03). In 8 eyes, the ICL was exchanged to a 0.5 mm bigger size and the vault was changed from 0.07 mm (0.03-0.13) to 0.50 mm (0.12-1.01) (p < 0.01). The exchange operation was performed at 3.5 postoperative days (1-6) if the ICL was exchanged to 1 step smaller size, but the exchange operation was performed at 135 postoperative days (90-660) if the ICL was exchanged to 1 step bigger size (p < 0.01).

CONCLUSIONS:

ICL exchange to 1 step smaller or bigger size is an effective method to correct unideal postoperative vault to a more ideal vault size. The exchange to 1 step smaller size ICL tended to be performed sooner.
