Summary

This trial will test whether using an OCT machine to guide a laser results in better vision for patients with corneal scars or defects.

Who is the study for?
This trial is for individuals with vision problems due to superficial corneal opacities and irregularities that can be treated with PTK, leaving at least 250 µm of the cornea. It's not suitable for those who can't stay still for OCT imaging, commit to follow-up visits, have deep corneal issues, or other eye conditions like cataracts or glaucoma.
What is being tested?
The study tests if using OCT to guide laser settings improves vision in patients undergoing phototherapeutic keratectomy (PTK) for removing scars and defects on the front part of the cornea.
What are the potential side effects?
Potential side effects may include discomfort in the eye, temporary visual disturbances, sensitivity to light, and a risk of infection or inflammation post-procedure.
