Surgical management of ectatic corneal disorders
Ectatic disorders of the cornea such as keratoconus, pellucid marginal degeneration and post–refractive surgery corneal ectasia are characterized by progressive corneal thinning, irregular astigmatism and decreased visual acuity. Over the last decade, there has been a paradigm shift from penetrating keratoplasty to lamellar keratoplasty for the management of primary as well as acquired corneal ectasia. This article reviews some of the surgical approaches to the management of ectatic corneal diseases.
