Comparison of three different instruments for vault measurements after implantable collamer lens implantation
Vault values measured by Pentacam are lower than those obtained by CASIA II and UBM, with UBM yielding the highest mean vault values. Measurements from the three instruments are not interchangeable but can serve as mutual references due to their significant correlation and good overall consistency. Pentacam and CASIA II demonstrate the highest consistency in vault measurement. Notably, when the vault value is ≤250 µm, the consistency between Pentacam and the other two instruments decreases significantly.
