. Purpose: To describe the outcome in vision and refraction of phototherapeutic keratectomy (PTK) in Salzmann's nodular degeneration (SND). Methods: Five eyes of four patients underwent PTK with the objective of restoring an acceptable refractive status and improving visual acuity. This surgical technique aims to make the nodules level with the corneal surface using an excimer laser. Results: Best corrected visual acuity (BCVA) improved in all five eyes. Astigmatism was reduced in four eyes and increased somewhat in one. During the observation period one eye suffered a late recurrence that required a penetrating graft. Conclusion: Salzmann's nodular degeneration is a rare disease that is sometimes difficult to diagnose as it has some resemblance to other diseases. The aetiology of the disease is unknown. Phototherapeutic keratectomy is a safe and effective mode of treatment. Recurrences occur with time.
