Introduction
• Posterior chamber phakic intraocular lens (pIOL), effective for the correction of moderate to high ametropia
• The Visian implantable collamer lens (ICL; STAAR Surgical, Monrovia, CA)– Posterior chamber pIOL placed behind the iris
with the haptics resting on the ciliary sulcus

• The pIOL models have undergone improvements to minimize complications
• The newer V4c model is designed with a 0.36mm central hole to overcome acute pupillary block

Purpose
• To determine the incidence, etiology, risk factors and management of complications following implantation of phakic posterior chamber ICL V4 and its newer version ICL V4c.

Patients and Methods
• Retrospective review • Consecutive clinical case series. • Inclusion:• Patients who underwent either spheric or
toric ICL implantation between +8 to -24 D sphere and 0 to -6.5 cylinder

Results
• A total of 406 eyes were included, 349 ICL V4 and 57 ICL V4c model.
• 20 eyes presented complications (4.92%)• Mean follow-up of 47±31 months (3-127)– Myopic: n=204– Hyperopic: n=8– Toric: n=194
