Optical Coherence Tomography Guided Transepithelial Phototherapeutic Keratectomy
Sponsor: Oregon Health and Science University
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.

OCT-guided laser phototherapeutic keratectomy
Preoperative measurements from the OCT are used to assist the calculation in deciding the laser depth settings for removal of anterior corneal opacities and defects in the phototherapeutic PTK procedure. The surgeon uses the OCT data to plan a range of treatment parameters to remove most of the opacity while preserving at least 250 microns of residual corneal stroma.
