Factors affecting vaulting after implantable collamer lens implantation.
To evaluate the vaulting of the STAAR Implantable Collamer Lens (ICL) over the crystalline lens after implantation.



One hundred twenty-three eyes of 68 patients with myopic refractive errors of -3.25 to -22.75 diopters undergoing ICL implantation were examined retrospectively. The magnitude of the central vaulting of the ICL was assessed quantitatively using slit-lamp microscopy at 3 months after surgery. Multiple regression analysis was used to assess the factors affecting the amount of vaulting.



The mean central vaulting 3 months after surgery was 603.6 +/- 259.6 microm. Explanatory variables relevant to the vaulting were, in order of influence, the horizontal white-to-white distance (partial regression coefficient B = 0.268, P = .0002) and patient age (B = -0.007, P = .011).



Although the majority of the variance remains unexplained, younger patients' eyes and eyes with greater white-to-white distances are more predisposed to have higher ICL vaulting over the crystalline lens.
