摘要:Purpose To investigate changes in corneal endothelial cell density over 5 years after implantation of Artiflex lenses (Ophtec BV, Groningen, The Netherlands) and to explore the influence of anterior chamber depth and volume on changes in endothelial cell density. Methods This study included 146 eyes of 88 patients implanted with foldable phakic iris-fixation intraocular (Artiflex) lenses for myopia correction from March 2009 to March 2014. To simulate chronological changes in endothelial cell density with age, we collected normal endothelial cell density data from 100 healthy subjects aged 20, 25, or 30 years, and compared the changes among these groups at 5 years after surgery. Changes in corneal endothelial cell density were compared among four groups to which subjects were assigned based on the distance from the intraocular lens to the corneal endothelium, and the volume and depth of the preoperative anterior chamber. Results The mean endothelial cell density, pre-operatively and at 1, 3, and 5 years post-operatively, was 3,038.8 ± 223.2, 2,985.3 ± 235.5, 2,905.1 ± 231.3, and 2,814.9 ± 250.5 cells/mm 2 , respectively (1.73%, 4.36%, and 7.31% reduction, respectively, vs. pre-operatively, p < 0.001). These differences were greater than those observed among different age groups (2.2% difference between 20- and 25-year-olds, and 1.2% difference between 25- and 30-year-olds, p < 0.001). A shorter distance from the lens to the endothelium and smaller anterior chamber volume were associated with greater decreases in endothelial cell density following surgery. Conclusions Corneal endothelial cell density significantly decreased during a 5-year follow-up after Artiflex lens implantation. The distance from the intraocular lens to the corneal endothelium, and the anterior chamber volume, were negatively correlated with the rate at which endothelial cell density decreased over time.
