Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients receiving PTK treatment at our center; 2. Age between 18 and 80; 3. Have a clear indication for PTK surgery and have completed standard PTK treatment; 4. Have complete preoperative examination data, including uncorrected or corrected vision, refractive status, and corneal-related tests; 5. Corneal epithelial thickness measurement data is available during pre- and post-operative follow-ups (e.g., anterior segment OCT or other relevant tests); 6. Prospective patients voluntarily participate in this study and sign the informed consent form.
Exclusion criteria
Exclusion criteria: 1. People who have previously undergone corneal refractive surgery or other surgeries that might affect corneal structure; 2. People with other eye conditions that could affect corneal shape or corneal epithelial thickness, such as keratoconus, keratitis, severe dry eye, corneal degeneration, or malnutrition; 3. People with serious eye diseases that affect vision assessment, like severe cataracts, glaucoma, retinal diseases, or optic nerve disorders; 4. People whose pre- or post-operative clinical data is incomplete, making it impossible to obtain the main research indicators; 5. People who did not complete the required follow-ups after surgery or lack key follow-up examination data; 6. Other situations that the researchers believe make someone unsuitable for this study.
