简要总结
The purpose of this long term safety study is to estimate the annualized endothelial cell loss (ECL) rate (for up to 10 years following date of implantation) of subjects previously implanted with the ACRYSOF CACHET Phakic Intraocular Lens (L-series) from precursor clinical studies C-02-23, C-02-40, C-03-21 and C-05-57.
详细描述
Subjects previously enrolled in protocols C-02-23 (NCT00726024), C-02-40 (NCT00727805), C-03-21 (NCT00726297), and C-05-57 (NCT00727688) who received an L-series lens either in the first eye or second eye (including those who were explanted) were enrolled in this open-label, non-randomized, non-controlled, extension study in which they attended postoperative visits for up to 10 years following the date of implantation. Subjects could enroll in the study at any time, thus the Entrance Visit may have coincided with any visit (Year 4 to Year 10).

结局指标
主要结局
Central Endothelial Cell Density (All Eyes)
时间窗: Year 4 to Year 10 postoperative from previous study (C-02-23, C-02-40, C-03-21, and C-05-57)
A microscope was used to photograph corneal endothelial cells (cells on the back of the cornea). Three images at the center of the cornea were obtained and sent to a central reading center for analysis. All recorded data from images were used in the analysis. A higher value for density represents a healthier cornea.
