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

ABSTRACT

PURPOSE: To evaluate the stability of the postoperative vault of the Intraocular Phakic Contact Lens (IPCL) five years after implantation. SETTING: Clínica de Ojos Dr. Nano, Olivos (Buenos Aires), Argentina. DESIGN: Retrospective case-series study. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
