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.
目的
描述光治疗性角膜切削术（PTK）治疗 Salzmann 结节状变性（SND）的视力和屈光结果。
方法
4 例患者的 5 只眼接受了 PTK，目的是恢复可接受的屈光状态并提高视力。该手术技术旨在使用准分子激光使结节与角膜表面齐平。
结果
所有 5 只眼的最佳矫正视力（BCVA）均有改善。4 只眼的散光减少，1 只眼的散光略有增加。在观察期内，1 只眼出现晚期复发，需要进行穿透性角膜移植。
结论
Salzmann 结节状变性是一种罕见疾病，有时难以诊断，因为它与其他疾病有一些相似之处。该疾病的病因尚不清楚。光治疗性角膜切削术是一种安全有效的治疗方式。随着时间的推移会出现复发。
