Abstract
Background. Phototherapeutic keratectomy (PTK) is a safe and effective procedure for the treatment of superficial corneal pathology.
Purpose. We aimed to highlight the use of PTK for the treatment of subepithelial corneal infiltrates (SCI). hototherapeutic keratectomy (PTK) is a safe and effective procedure for the treatment of superficial corneal pathology.
Case description. A 68-year-old man presented for a blurred vision of the right eye (RE), 1 year after a healed episode of epidemic keratoconjunc- tivitis (ECK). In the RE, Best corrected visual acuity (BCVA) was reduced to 20/70, Slit lamp examination showed multiple central SCI. Left eye (LE) examination showed no abnormalities. PTK was indicated with an optic zone of 8mm and a treatment depth of 90 μm. At 1-month post PTK, BCVA was 20/32, and we noted a total resolution of SCI with clear cornea.
Conclusion. PTK is a promising, minimally invasive extraocular alternative to lamellar or penetrating keratoplasty with shorter duration of fol- low-up, in cases with SCI with satisfactory refractive and visual outcomes.
