Optical Coherence Tomography Guided Transepithelial Phototherapeutic Keratectomy
Trial Parameters
Brief Summary
Optical Coherence Tomography (OCT) machines are non-contact instruments that can measure the depth of scars and other causes of cloudiness in the front of the cornea. The purpose of this study is to determine whether OCT-guided settings for the lasers used for removal of corneal scars and other partial-thickness corneal defects result in improved vision in patients receiving these procedures.
Eligibility Criteria
Inclusion Criteria: * Patients with vision primarily limited by superficial opacities and irregularities that could be removed by PTK while leaving at least 250 µm. Exclusion Criteria: * Inability to give informed consent * Inability to maintain stable fixation for OCT imaging * Inability to commit to required visits to complete the study * Deep corneal opacities and irregularities * Cataracts, retinal disease, glaucoma, or other eye conditions that may limit the visual outcome after surgery
