PURPOSE: To study changes in intraocular pressure (IOP) during the early postoperative period in eyes having implantation of a posterior chamber phakic intraocular lens (pIOL) (Visian Implantable Collamer Lens V4c). SETTING: Clínica Baviera, Instituto Oftalmológico Europeo, Madrid, Spain. DESIGN: Case series. METHODS: This retrospective review included the first consecutive eyes having implantation of a spherical or toric myopic pIOL with a central hole at Clínica Baviera from December 2011 to June 2012 by the same experienced surgeon. The IOP was evaluated preoperatively and 1 day, 1 week, and 1 month postoperatively. RESULTS: The study comprised 100 eyes. The mean IOP changed from 14.6 mm Hg ± 3.4 (SD) (range 8 to 26 mm Hg) preoperatively to 14.5 ± 4.6 mm Hg (range 6 to 30 mm Hg) 1 day postoperatively, 14.2 ± 4.2 mm Hg (range 6 to 29 mm Hg) at 1 week, and 12.3 ± 3.4 mm Hg (range 9 to 24 mm Hg) at 1 month. No statistically significant changes were detected over time postoperatively (P>.2). No perioperative complications associated with the implantation of the pIOL were recorded. No pIOLs were explanted, no toric pIOL rotation was detected, and no pupillary block or acute angle closure was observed. CONCLUSION: The short-term clinical data for the new pIOL model with the central hole (KS-Aquaport) suggest that it is a safe and effective means for controlling postoperative IOP.
