Abstract Details


This study sought to identify associations between crystalline lens-related factors and central vault after Implantable Collamer Lens (ICL) implantation.


Hankou Aier Hospital, Wuhan, China.


This investigation was a retrospective clinical study included 320 eyes from 186 patients who underwent ICL implantation surgery. At 1 year after surgery, the central vault was measured using anterior segment optical coherence tomography (OCT). Preoperative anterior chamber depth (ACD), lens thickness (LT), lens position (LP, LP=ACD퟽�)and vault were analyzed to investigate the effects of lens-related factors on postoperative vault.


The mean vault was 513�Â�±215�Î�¼mat 1 year after surgery. Vault was positively correlated with preoperative ACD (r=0.495, P<0.001) and LP(r=0.371, P<0.001), but negatively correlated with LT (r=-0.262, P<0.001). Eyes with vaults<250�Î�¼m had shallower anterior chambers, thicker lenses and smaller LP than eyes in the other two vault groups(which had vaults�â�‰�¥250�Î�¼m) (P<0.000). Eyes with both ACD<3.1 mm and LP<5.1mm had greatly reduced vaults(P<0.000).


The crystalline lens could have an important influence on postoperative vault. Eyes with a shallower anterior chamber and a forward LP will have lower vaults. A larger size of ICL might be recommended for these eyes.
