Anterior segment photography and corneal topographic analysis were obtained preoperatively and postoperatively in all patients.Results: Six months after surgery, corneal astigmatism and corneal aberrations were reduced in all patients. A clear cornea was achieved in all cases. No complications were noted during the follow-up period.Conclusion: Diamond burr superficial keratectomy with application of mitomycin C is a potentially effective and simple procedure for treating patients with corneal scarring and high corneal astigmatism secondary to previous pterygium surgery.Keywords: diamond burr superficial keratectomy, astigmatism, pterygium surgery
