PTK for Treatment of Foreign Body-Related Scarring

This case involves a 47-year-old male patient who presented with blurred vision and glare due to a central corneal scar following the removal of a metal foreign body. We used the CASIA2 to assess the depth of the lesion and to plan the 
PTK procedure.

This case demonstrates the potential effectiveness of PTK in treating corneal scarring. The patient initially had a best corrected visual acuity (BCVA) of 0.8 in the affected eye.

After undergoing PTK, the BCVA improved to 1.2, and the patient was highly satisfied with the improvement in vision.

Slit lamp examination revealed almost no residual findings after PTK
