Bilateral Choroidal Effusión After ICL Implantation/de Rojas et al Figure 1. Slit-lamp photography of the (A and B) right eye and (C and D) left eye 1 day after surgery in the second eye (right) showing bilateral shallow anterior chamber with vault 0 and patent iridotomies in both eyes.

Vault was 0 in both eyes.
To our knowledge, we present the first report of cil- iochoroidal effusion after implantation of an ICL. How-ever, this condition has previously been considered a theoretical component in the differential diagnosis of shallow anterior chamber early after implantation of an ICL, with the following alternatives2-4: pupillary block glaucoma, oversized ICL, incision leakage, cil-iochoroidal effusion, suprachoroidal hemorrhage, and malignant glaucoma. In our case, the finding of patent iridotomy and vault 0, which indicated forward dis-placement of the natural lens, ruled out pupillary block induced by occluded iridotomy or excessive vaulting.
