**Study Summary for Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) Laser Treatment** Granular Corneal Dystrophy (GCD) is a rare eye condition that causes deposits in the cornea, the clear front part of the eye. This can blur vision. Currently, treatment involves surgery, but this study tests a laser called Nd:YAG, which may be less invasive. The laser aims to safely break down these deposits without major side effects. **Key Points:** - **Study Duration and Visits:** Participants have two follow-up visits after treatment: one week and three months later, with exams and imaging each time. - **Treatment Process:** The Nd:YAG laser treatment is done with local anesthesia and may require antibiotic eye drops for a week. - **Eligibility and Risks:** Participants must be over 18, have GCD, and be able to follow instructions. Risks include minor chances of corneal scarring or inflammation, but vision should not be affected since only peripheral deposits are treated. Participants will have their data protected and receive a unique code for study tracking. This study hopes to offer a safer, non-surgical option for GCD patients.
