Implantable Collamer Lens for XXXX : Assessment 12 Years After Implantation.

@entity940 @entity231 @entity1714 @entity260
PURPOSE: To evaluate the long-term refractive and visual stability and the risks related to the implantation of Implantable Collamer Lens (ICL; STAAR Surgical, Monrovia, CA) phakic intraocular lens (PIOL) for @entity1714 . METHODS: This retrospective, consecutive, cumulative clinical study was performed in a group of 144 eyes implanted with ICL PIOL for @entity1714 . Only the cases with clinical data available 12 years after the implantation were included in the series. Corrected distance visual acuity (CDVA), uncorrected distance visual acuity, spherical equivalent, refractive @entity940 , endothelial cell density, ICL vaulting, and @entity260 were analyzed. RESULTS: Mean spherical equivalent refraction was -16.90  4.26 diopters (D) preoperatively and -1.77  1.93 D 12 years postoperatively. Mean CDVA at the first and last visit were 0.31  0.19 logMAR and 0.22  0.22 logMAR, respectively (Mann-Whitney U test, P<.001). Twelve years postoperatively, 8.9% of eyes had lost more than two lines of CDVA. The incidence of clinically relevant @entity231 (13.88%) was significantly linked to the use of the V3 model ICL (chi-square test, P=.007). During the follow-up period, a significant reduction in PIOL vaulting was observed (Kruskal-Wallis test, P<.05), and the mean endothelial cell density decreased by 19.75%. CONCLUSIONS: The ICL PIOL provided good refractive outcomes and stability in the long term. The incidence of @entity231 is low when the latest models of this PIOL are used.
