Salzmann’s Nodular Degeneration (SND) is characterized by multiple superficial blue-white nodules in the midperiphery of the cornea. The pathogenesis is unknown and usually develops following ocular surface inflammation or surgery as an end-stage of the corneal scarring pathway. SND is usually asymptomatic but may affect vision if located centrally. Histologically, SND is composed of dense irregularly arranged collagen tissue between epithelium and Bowman’s layer or beyond; therefore, patients may develop recurrent corneal erosions or corneal scarring.
Surgical removal, phototherapeutic keratectomy (PTK) with or without the use of topical mitomycin C (MMC), lamellar, or penetrating keratoplasty have been used in the treatment of this disease. Although PTK may restore a smooth ocular surface, the required laser ablation depth is significantly large and may be complicated with haze and refractive error. In contrast, superficial keratectomy followed by placement of PROKERA® is effective in restoring corneal surface integrity without haze.
PROKERA® allows regenerative healing to restore corneal surface integrity and improve the quality of vision after superficial keratectomy to remove Salzmann’s nodular degeneration or other similar diseases.
