简要总结
The purpose of this study is to assess the vision improvement achieved by patients with late stage dry age-related macular degeneration who received corneal treatments by a low vision aid device.
详细描述
The purpose of this study is to assess the vision improvement achieved by patients with late stage dry age-related macular degeneration who received corneal treatments by a low vision aid device. Patient records for patients with at least 12 months follow-up will be analyzed to determine measures of vision improvement including best spectacle-corrected distance and near visual acuity. Analyses will include descriptive statistics and correlation between outcomes and baseline characteristics.
