The Cornea and Laser Eye Institute is participating in a research study to determine if an investigational corneal inlay can safely and effectively reduce the need for reading glasses. Dr. Peter Hersh, the study doctor, will perform the procedures. The investigational AcuFocus Corneal Inlay (ACI) is intended to improve near vision in patients with presbyopia, which is the loss of near vision, and reduce dependency on reading glasses. Qualified participants will receive the procedure at no charge.
