Implantable Phakic Contact Lens: vault evaluation five years after surgery.

Abstract

To evaluate the stability of the postoperative vault of the Intraocular Phakic Contact Lens (IPCL) five years after implantation. Clínica de Ojos Dr. Nano, Olivos (Buenos Aires), Argentina. Retrospective case-series study. Myopic patients operated with the IPCL lens for spherical correction in which preoperative data were compared with different scenarios of postoperative vault at 1, 3 and 5 years after surgery. The main parameter to be evaluated was the vault obtained 5 years after surgery. A total of 140 eyes of 72 patients, aged 31.9 ±2.8 years old (21-50) were included. Most of the eyes (78.6 %) obtained a vault between 250 to 750 μm, while in 15% of the eyes it was less than 250, and 6.4% were greater than 750 μm. The vault evaluated 1, 3 and 5 years after surgery remained stable. Sub-capsular cataracts were detected in two eyes, with vault < 250 μm. A total of 50 eyes (35.7 %) had cysts in the sulcus (5 cases in the group of eyes with vault > 750 μm). No changes were detected in relation to intraocular pressure or endothelial cell count. In eyes implanted with the IPCL lens over 5 years, it has been observed that the vault remained stable over time. The proportion of eyes with cysts was higher in eyes with vaults larger than 750 μm.
