Burr-Assisted Peripheral Superficial Keratectomy for the Treatment of Persistent Symptomatic Peripheral Corneal Edema.

PURPOSE: To describe a simple technique of diamond burr-assisted superficial keratectomy for the treatment of peripheral corneal edema.

CASES PRESENTATION: Two patients with persistent symptomatic peripheral corneal edema underwent superficial keratectomy with the use of a diamond ophthalmic burr. The efficacy of the treatment was evaluated clinically as well as with anterior segment optical coherence tomography. During the postoperative follow-up period, no adverse events were observed and corneal edema reduced significantly. The patients were asymptomatic, no epithelial cysts could be identified clinically, and visual acuity remained unchanged.

CONCLUSION

Peripheral superficial keratectomy could be an effective alternative for the treatment of peripheral, symptomatic corneal edema.
